1. INTRODUCTION
Herbal remedies have been used for thousands of
years. Early in human history, people practiced herbal
medicine as a magical or religious healing art (Baker,
1965). Today, a lot of people use herbal medicine or
rely on them. There are many various drug plants. One
of them is lemon balm (Melissa officinalis L.), in other
words bee herb or sweet balm.
Lemon balm, member of the family Lamiaceae
(formerly Labiatae) in scientific classification is a
perennial herb that is, one that lives at least three
years. It is bushy and upright, reaching a height of
about 1 m. The soft, hairy leaves are 2 to 8 cm long
and either heart-shaped. The leaf surface is coarse and
deeply veined, and the leaf edge is scalloped or
toothed. White or pale pink flowers which consist of
small clusters of 4 to 12 blossom in the summer. It is
commonly referred to as Lemon Balm because of its
lemon-like flavor and fragrance (İlisulu, 1992;
Anonymous, 2003).
Lemon balm, one of the important medicinal plant
species mainly grown in natural flora -especially in
Mediterranian region- of Turkey, is native to southern
Europe and northern Africa, and east as far as the
Caucasus and northern Iran. Its wild types are in all
Mediterranean countries and South part of the Alps.
There are exist on other three subspecies which are
naturally expended in our wild flora; subsp. officinalis,
subsp. altissima and subsp. inodora (Davis, 1982;
İlisulu, 1992; Anonymous, 2003). It is recorded that
the plant is mainly grown in Germany, France, Italy,
Romania, Bulgaria, and North America (Ceylan,
1987, Tansı ve Özgüven 1995). Özhatay et al. (1997)
reported that the subspecies of M. officinalis’ are
evaluated in domestic markets and they are also on the
list of the exported medicinal and aromatic plants.
It is used in traditional medicine from ancient
times. French monks and nuns, and Paracelsus (1493-
1541), Swiss physician and chemist, prepared tonics,
called as “life elixir”, contain lemon balm, and used.
English writer John Evelyn (1620-1706), described
this plant as “ruler of brain, strengthening to mental,
and removing from melancholia”. Its essential oil was
named “bal-smin” or “leader of the oils” in Hebrew.
Avicenna recommends that lemon balm strengthened
heart (Asımgil, 2001; Anonymous, 2003).
Today, lemon balm is used in various branches of
industry (such as medicine, perfume and cosmetic,
and food etc.) in a lot of countries of the world.
2. THE ESSENTIAL OIL OF LEMON BALM
AND ITS COMPONENTS
Lemon balm essential oil, obtained from fresh or
dried flower, leaf, and branches of this plant by water
R. Bahtiyarca Bağdat, B. Coşge
117
steam distillation or chemical extraction, is
characteristic with fresh lemon odor, and light yellow
colored. Its viscosity is lighter than that of water
(Anonymous, 2003). It was desired that this value
should not be lower than 0.05 % (Baytop, 1984).
The main components of the essential oil are 39%
citronellal, 33% citral (citronellol, linalool) and 2%
geranial. In addition, this oil contains such as
threeterpinene, phenol carbon-acid (rosmarinic acid),
and flavonglychoside acids in low ratio. There are also
caffeic acid (a kind of tannin), several flavonoids
(luteolin-7-O-glucoside, isoquercitrin, apigenin-7-O-
glucoside, and rhamnocitrin), rosmarinic acid, ferulic
acid, methyl carnosoate, hydroxycinnamic acid, and 2-
(3', 4'-dihydroxyphenyl)-1,3-benzodioxole-5-aldehyde
and some other aldehydes: beta-caryophyllene, neral,
and geranyl acetate. (Kucera and Herrmann, 1967;
Baytop, 1984; Zeybek, 1985; Mulkens and
Kapetanidis, 1987; Peake et al., 1991; Dimitrova et al.,
1993; Vaverkova et al., 1995; Chevallier, 1996;
Ceylan, 1997; Tagashira and Ohtake, 1998; Hohmann
et al., 1999).
Variability in both the content and quality of
essential oil has been observed in herb and leaf drugs
depending on the harvest cut height of plant
(Mrlianova et al., 2001 b), time and number of cut
(Ceylan, 1987).
Results from selected studies currently undertaken
on lemon balm essential oil and its compenent are as
follow.
That the essential oil content in the leaves at the
stage just prior to blooming, or at the onset of
blooming, ranged from 0.06 to 0.16 % (V/m), and the
maximal essential oil content (0.09 to 0.45%) was in
the plants from the second harvest in lemonbalm from
17 European regions; the essential oil content in
cultivar Citra from Bratislav was 0.13% and 0.23-
0.27%, in 1st harvest and 2nd harvest, respectively were
determined by Mrlianova et al. (2001 a).
Mrlianova et al. (2001 b) were recorded that three
different cuts were carried out on cv. Citra and the oil
content in the herb was highest in the top third (0.13%
V/m), satisfactory in the herb including both and
middle thirds (0.08% V/m) and lowest in the whole
herb (0.06% V/m). The essential oil content in the
leaves of respective herbs was in the range 0.39%-
0.14% V/m (top third part-whole aerial part). Citrals
(A and B) were 55.79, 48.46, and 59.74 and 56.87% in
the top third part of the herb, the whole herb, and the
leaves from those parts, respectively. Likewise, beta-
caryophyllene was 5.01, 3.87, and 6.97 and 5.13%;
beta-caryophyllene oxide was 17.19, 24.07, and 15.64
and 17.82%; citronellal was 2.73, 5.51, and 2.82 and
6.44%.
Sarı and Ceylan (2002) reported that the essential
oil ranged from 0.03 to 0.067% besides, the main
component in essential oil was geraniol (33.13 to
53.68 %), and the others were neral, citronellal, and β-
pinen in the study, carried out with 11 Melissa
populations in Menemen and Bozdağ.
Tınmaz et al (2001) was reported that the highest
essential oil’s ratio (0.14%) was obtained from the
plants, cut in the beginning of blooming, grown in
Çanakkale ecological conditions.
Essential oil obtained from a few different
populations of Melissa officinalis L. cultivated in
Poland had been investigated by Patora et al. (2003).
In their study, the content of essential oil in the leaves
and herb were recorded as 0.08-0.25 ml/100g and
0.06-0.167 ml/100g, respectively. In addition,
essential oil was in the plant material from
experimental patch then that from commercial
cultivations, and essential oil of the fresh material was
slightly higher than one of the dried one. Also, it was
observed that the contents of citral, citronellal,
linalool, nerol, geraniol beta-caryophyllene and beta-
caryophyllene oxide among the populations were
different greatly.
Patora and Klimek (2002) have isolated six
flavonoids from the leaves of lemon balm. These
flavonoids have been luteolin, luteolin 7-O-beta-D-
glucuronopyranoside, apigenin 7-O-beta-D-
glucopyranoside, luteolin 7-O-beta-D-
glucuronopyranoside, luteolin 3-O-beta-D-
glucuronopyranoside and luteolin 7-O-beta-D-
glucopyranoside-3-Obeta-D-glucuronopyranoside.
The last three glycosides have been found in lemon
balm for the first time and luteolin 7-O-beta-D-
glucopyranoside-3-Obeta-D-glucuronopyranoside is
a new compound in plants.
3. USING FIELD OF LEMON BALM ESSENTIAL OIL
a- In Medicine:
The World Health Organization reported that there
are approximately four millions people on the world
(which are constituing 80% of the total population)
trying to cure their health problems with herbal drogs.
In addition, in the developed countries, 25% of the
medicines -sold with rescription- were obtained from
herbal origined (vimblastin, reserpine, quinine, aspirin
etc.) plants (Farnsworth, 1990; Principe, 1991). There
are made numerous clinical and epidemiological
studies on herbs all over the world, with using several
enzymatic systems for exposing the bioactive material
in them and maintaining the research studies for
producing the high productive material. Almost huge
İnternational Medicine Companies have, well or
medium equipped, an “herbal products research unit”
in their constitution (Başer, 2004).
There are numerous herbs which have traditionally
been used in folk medicine. Including lemonbalm
(Melissa officinalis L.), marijuana (Cannabis sativa),
ginger (Zingiber officinale), ginkgo (Ginkgo biloba)
and Peppermint oil topically was found to be as
effective as oral paracetamol for headache control and
now being investigated as possible migraine
prophylactics (Baldwin, 1987; Gobel, 1996).
Lemon balm has traditionally been used due to its
memory enhancing properties, but using of which is
currently more widely used as sedative or calm,
The Essential Oil of Lemon Balm (Melissa officinalis L.), Its Components and Using Fields
118
spasmolytic and antibacterial agent and sleep aid has
been more popular recently (Coleta et al., 2001;
Kennedy et al., 2002; Kennedy et al., 2003; Sadraei et
al., 2003; Kennedy et al., 2004; de Sousa et al., 2004).
In addition these properties that are very important to
human healthy, today researches about essential oil of
lemon balm have been continued intensively.
Khayyal et al. (2001) have prepared the extracts
from the plants Iberis amara, Melissa officinalis,
Matricaria recutita, Carum carvi, Mentha piperita,
Glycyrrhiza glabra, Angelica archangelica, Silybum
marianum and Chelidonium majus, singly and
combined in the form of a commercial preparation,
STW 5 (Iberogast) and a modified formulation, STW
5-II, lacking the last 3 constituents. These extracts
were tested for their potential anti-ulcerogenic activity
against indometacin induced gastric ulcers of the rat as
well as for their antisecretory and cytoprotective
activities. All extracts produced a dose dependent anti-
ulcerogenic activity associated with a reduced acid
output and an increased mucin secretion. According to
this study results, the anti-ulcerogenic activity of the
extracts was also confirmed histologically. On the
other hand, the cytoprotective effect of the extracts
could be partly due to their flavonoid content and to
their free radical scavenging properties. Free radicals
occur in body chemistry, in processes such as the
destruction of invading organism by white blood cells.
Free radicals might play a role in various maladies,
such as arthritis, heart disease, and Alzheimer's
disease. When natural enzyme controls fail, free
radicals in the body attack lipids, proteins, and nucleic
acids. Especially, the beta glucan in essential oil,
protects the body from free radicals destroying effects
taking the role of antioxidant.
Akhondzadeh et al. (2003) carried out the
investigation to asses the efficacy and safety of lemon
balm extract using a fixed dose (60 drops/day) in
patients with mild to moderate Alzheimer’s disease.
Patients with mild to moderate Alzheimer’s disease
aged between 65 and 80 years were treated for four
months, and divided two groups randomly to placebo
or fixed dose of lemon balm extracts. At four months,
Melissa extract produced a significantly better
outcome on cognitive function than placebo. Besides,
there were no significant differences in the two groups
in terms of observed side effects except agitation,
which was more common in the placebo group. With
respect to conclusions, Melissa officinalis extract is
value in the management of mild to moderate
Alzheimer’s disease and has a positive effect on
agitation in such patients.
Drozd and Anuszewska (2003) reported that the
effect of water extracts from leaves of Melissa
influenced on the immune system, in both humoral
and cellular response.
Kennedy et al. (2004) have suggested that the
potential for lemon balm to mitigate the effects of
stress.
De Sousa et al. (2004) performed the study on
antitumoral and antioxidant activities of lemon balm
essential oil. The chemical composition and the
biological activities of lemon balm essential oil
obtained under controlled harvesting and drying
conditions. Obtained findings showed that this oil was
very effective against a series of human cancer cell
lines (A549, MCF-7, Caco-2, HL-60, and K562) and
mouse cell line (B16F10). Also, this oil possessed
antioxidant activity, as evidence by reduction of 1, 1-
diphenyl-2-picryl-hydrazyl (DPPH). These results
pointed out to the potential use of lemon balm
essential oil as an antitumoral agent.
Savino et al., (2005) invastigated that the colic in
breastfed infant. The result of their studies shows that
the colic in breastfed infant improves within 1 week
of treatment with an extract based on Matricariae
recutita, Foeniculum vulgare and Melissa officinalis.
Bolkent et al., (2005) reported that the
administration of Melissa officinalis L. extract
reduced total cholesterol, total lipid, ALT, AST and
ALP levels in serum, and LPO levels in liver tissue,
moreover increased glutathione levels in the tissue. As
a result, it was suggested that Melissa officinalis L.
extract exerted an hypolipidemic effect and showed a
protective effect on the liver of hyperlipidemic rats.
b- In Food:
The lemon-scented leaves add flavor to jellies,
liqueurs, fruit salads, and cold drinks (İlisulu, 1992;
Anonymous, 2003). In addition, results of a lot of
researches have showed that essential oil of lemon
balm and extracts (Melissa officinalis subsp.
officinalis and of Melissa officinalis subsp. inodora)
can be used as antioxidant (Marangui et al., 2004).
As known, antioxidant, type a molecule that
neutralizes harmful compounds is called as free
radicals (Anonymous, 2003).
The essential oils from aerial parts of Melissa
officinalis, Lavandula angustifolia, Salvia officinalis,
and Mentha piperita were analyzed using gas
chromatography and gas chromatography-mass
spectrometry by Araujo et al. (2003). Their
antimicrobial activities were evaluated against five
food spoilage yeasts, Torulaspora delbrueckii,
Zygosaccharomyces bailii, Pichia membrainifaciens,
Dekkera anomala, and Yarrowia lipolytica.
Saccharomyces cerevisiae was also used as a
reference. According to results of this research, the
essential oil of M. officinalis at 500 microg/ml
completely inhibited the growth of all yeast species.
The main component of the oil of lemon balm was
citral (neral plus geranial) (58.3%), which showed a
marked fungi toxic effect, contributing to its high
activity.
Mimica et al. (2003) have described antimicrobial
and free radical scavenging capacity (RSC) together
with the effects on lipid preoxidation (LP) of lemon
balm essential oil in their study. The antimicrobial
activity was tested against 13 bacterial strains and six
R. Bahtiyarca Bağdat, B. Coşge
119
fungi. The examined essential oil exhibited very
strong RSC; the most powerful scavenging
compounds were monoterpene aldehydes and ketons
(neral/geranial, citronellal, isomenthone, and
menthone) and mono- and sesquiterpene hydrocarbons
(E-caryophyllene). The most effective antibacterial
activity was expressed on a multiresistant strain of
Shigella sonei. A significant rate of antifungal activity
was exhibited on Trichophyton species.
Uzun et al., (2004) studied the traditional medicine
in North-West of Turkey (Sakarya province) by
interviewing local informants from several villages.
Plant species used to treat infections were tested for
antimicrobial activity. Information was collected for
46 plant species from 30 families and for 5 animal
species. Twenty four of the plant species were
cultivated. Most used families were Asteraceae,
Cucurbitaceae, Lamiaceae and Rosaceae and the most
used plants were Artemisia absinthium, Equisetum
telmateia, Lavandula stoechas, Melissa officinalis,
Tussilago farfara and Urtica dioica. A total of 139
medicinal uses were obtained. Plants are used mainly
for infectious diseases (18%), for neurological and
psychological disorders (13.7%), cardiovascular
disorders (13%), skin disorders (12.2%) and
respiratory disorders (10.1%). Extracts were tested in
vitro for antimicrobial activity against Staphylococcus
aureus ATCC 65538, Staphylococcus epidermidis
ATCC 12228, Escherichia coli ATCC 8739,
Klebsiella pneumonia ATCC 4352, Pseudomonas
aeruginosa ATCC 1539, Salmonella typhi, Shigella
flexneri, Proteus mirabilis and Candida albicans
ATCC 10231, using microbroth dilution technique
according to National Committee for Clinical
Laboratory Standards (NCCLS). This research showed
that Arum maculatum, Datura stramonium, Geranium
asphodeloides and Equisetum telmateia petroleum
either extracts had MIC values of 39.1 microg/ml, 78.1
microg/ml, 78.1 microg/ml and 39.1 microg/ml,
respectively against Staphylococcus epidermidis.
Datura stramonium petroleum either extract had a
MIC value of 39.1 microg/ml against Escherichia coli
and Trachystemon orientalis ethanol extract had a
MIC value of 39.1 microg/ml against Escherichia coli.
The antimicrobial activity of Arum maculatum,
Equisetum telmateia, Geranium asphodeloides,
Plantago intermedia, Senecio vulgaris and
Trachystemon orientalis has been reported here for the
first time.
Yadav et al. (2005) assessed various leaf structural
and chemical features as possible predictors of the size
of the phyllosphere bacterial population in the
Mediterranean environment. They examined eight
perennial species, naturally occurring and coexisting
in the same area, in Halkidiki (northern Greece). They
are Arbutus unedo, Quercus coccifera, Pistacia
lentiscus, and Myrtus communis (evergreen
sclerophyllous species), Lavandula stoechas and
Cistus incanus (drought semideciduous species), and
Calamintha nepeta and Melissa officinalis (nonwoody
perennial species). M. communis, L. stoechas, C.
nepeta and M. officinalis produce essential oil in
substantial quantities. It is fond that, the aromatic
plants are on average more highly colonized than the
other species, whereas the nonwoody perennials are
more highly colonized than the woody species. Leaves
with water content >73% are the bacteria most highly
colonized.
c- In Perfume and Cosmetic Industry:
Due to hydrosol its essential oil and the strongly
scented leaves are also used in perfumes and natural
cosmetics. Hydrosol is the watery solution of the
distillation that contains both the water-soluble plant
components and micro-drops of essential oil. Because
of they acidify the water or the product which is
beneficial to the skin or in the body. Thus the
hydrosol acts as a healing anti-inflammatory and mild
but therapeutic antiseptic. Bacteria do not live well an
in acidic environment which is why acids such as
vinegar make good preservatives for such food items
as pickles Chilé peppers and Olives. Acidic
environments are astringent and so the hydrosols are
useful in skin care products as astringents that
constrict and contract the tissues.
The hydrosols can be used externally in skin care
products as a douche or internally diluted and taken as
a tonic drink (Rose, 2000).
4. CONCLUSION
Lemon balm is a potential medicinal and aromatic
plant grown commonly most of our wild areas. Its
essential oil is currently used in medicine and
pharmacology (anti-tumor, anti-bacterial, anti-
microbial, antihistaminic, antispasmodic and
antioxidant, by means of its antiviral effect curing of
the herpes (Allahverdiyev et al., 2004), anti-
ulcerogenic, moderate Alzheimer’s disease,
modulation of mood and cognitive performance,
stimulating the immune system (against anti HIV-1)
(Yamasaki et al., 1998) and the heart, insect bites,
painful menstruation, colds, headaches, mumps,
insomnia, mild sedative and anti-depressant), (Foster
and Duke , 1990), in food industry (using it’s essential
oil for food spoilage yeasts to extending the storage
periods, in soft drinks industry because its fresh lemon
tastes and herbal tea industry) and in cosmetic
industry (containing hydrosol for curing dermatogical
problems).
Valuable essential oil which the plant contains a
very less amount has already been imported although
it’s large extension in our flora unfortunately, this
condition causes a loss of foreign currency
approximately one million $ every year, according to
data of Under Secretariat of The Prime Ministry for
Foreign Trade. There are some studies about lemon
balm just recently in our country. In order to meet
industry’s demand and export, new lines and cultivars
containing acceptable volatile oil should be improved.

The most promising anticonvulsant phytocompounds were explored in this work using docking, molecular dynamic (MD) simulation, and Molecular Mechanics-Poisson–Boltzmann Surface Area (MM-PBSA) approaches. A total of 70 phytochemicals were screened against α-amino-3-hydroxyl-5-methyl-4-isoxazole propionic acid (AMPA), N-methyl-d-aspartate (NMDA), voltage-gated sodium ion channels (VGSC), and carbonic anhydrase enzyme II (CA II) receptors, and the docking results were compared to the reference drug phenytoin. Amentoflavone displayed the highest affinity for AMPA and VGSC receptors, with docking scores of − 10.4 and − 10.1 kcal/mol, respectively. Oliganthin H-NMDA and epigallocatechin-3-gallate-CA II complexes showed docking scores of − 10.9 and − 6.9 kcal/mol, respectively. All four complexes depicted a high dock score compared to the phenytoin complex at the binding site of the corresponding proteins. The MD simulation investigated the stabilities and favorable conformation of apoproteins and ligand/reference-bound complexes. The results revealed that proteins AMPA, VGSC, and CA II were more efficiently stabilized by lead phytochemicals than phenytoin binding. Additionally, principal component analysis and MM-PBSA results suggested that these lead phytocompounds have good compactness and strong binding free energy. Further, physicochemical and pharmacokinetic studies revealed that these final lead phytochemicals would be suitable for oral intake, have sufficient intestinal permeability, and have the ability to cross the blood–brain barrier (BBB). Comprehensively, this study predicted amentoflavone as the best lead phytochemical out of the 70 anticonvulsant phytocompounds that can be used to treat epilepsy.

The Lamiaceae family is an essential medicinal plant family. Melissa officinalis L. is a well-known medicinal plant of Lamiaceae. It was aimed to investigate the effects of Melissa officinalis infusion given to rats with hyperlipidemia and hypercholesterolemia in this study. It is seen that the high-fat diet (HFD) group causes weight gain from the third week. VLDL, LDL, HDL and cholesterol levels were found statistically significant differences (p˂0.05), fed a cholesterol-enriched high-fat diet group (HFD) compared to the control. It is seen that the cholesterol level of the high-fat diet+Melissa officinalis infusion (HFD+MOI) group was statistically significantly (p˂0.05). lower than the HFD group. In addition, the group in which Melissa officinalis was applied had positive effects on the antioxidant system and reduced the total oxidant system. The fact that the IFN-γ level of the HFD group was higher than the control indicates that the diet may have an inflammatory effect. As a result, HFD application with cholesterol caused hyperlipidemia and hypercholesterolemia in rats. The cholesterol-lowering effect of Melissa officinalis is observed. Remarkably, Melissa officinalis did not alter serum calcium levels while lowering cholesterol. In addition, it can said that HFD has a strengthening effect on the antioxidant system on oxidative stress.

Abstract Thaumetopoea wilkinsoni Tams. is the most important pine defoliator in the Mediterranean Basin and can cause serious growth losses on trees. At this point, the purpose of this study was to investigate the larvicidal effects of eight plant essential oils as biological control agents for the pine processionary moth. For this purpose, Artemisia vulgaris L., Juniperus drupacea Labill., Melissa officinalis L., Ocimum basilicum L., Origanum majorana L., Rosmarinus officinalis L., Sideritis leptoclada O. Schwarz & P.H. Davis and Vitex agnus-castus L. essential oils were tested on the fourth/fifth larval periods of T. wilkinsoni. The essential oils from the eight plants were obtained by hydrodistillation and analysed by GC/MS. The most abundant compounds from each studied species were as follows: 1,8-cineole (20.68%) for R. officinalis, β-pinene (26.73%) for S. leptoclada, linalool (38.67%) for O. majorana, p-mentha-1,5-dien-8-ol (36.44%) for M. officinalis, eugenol acetate (38.78%) for O. basilicum, 1,8-cineole (22.10%) for V. agnus-castus, d-limonene (45.21%) for J. drupacea and trans-β-caryophyllene (21.22%) for A. vulgaris. The results show that all eight essential oils exhibited promising efficacy in a dose-dependent manner on T. wilkinsoni larvae after 24 hours. The highest larvicidal effect was obtained from J. drupacea, followed by O. basilicum, with LC50 values of 73.55 and 95.04 ppm, respectively. The data obtained from this study clearly indicate that J. drupacea and O. basilicum essential oils have the potential to have larvicidal effects and these findings point to the possibility of using the essential oil of the current species to control T. wilkinsoni.

Even though Melissa officinalis L. (lemon balm, fam. Lamiaceae) is a well-known medicinal, aromatic, and spicy plant, and its physicochemical profile and biological activity have been investigated, there is no detailed research regarding the influence of solvent nature (polarity) on the extraction of active compounds (total polyphenols and total flavonoids) and antioxidant activities of the obtained extracts. Therefore, this study aimed to evaluate the polyphenol and flavonoid contents, as well as the antioxidant potential of lemon balm extracts obtained by varying the polarity of the extraction solvents (methyl alcohol, acetone, ethyl acetate, and deionized water) and using three extraction techniques (maceration-MAC, ultrasound-UAE, and microwave-assisted extraction-MAE). Two in vitro tests (ABTS and FRAP assays) were used to determine the antioxidant activity of the extracts. Total tannin and total protein contents, extraction yield, and physical properties of the selected extracts were measured as well. The highest content of polyphenols was found for the methanolic and water extracts obtained by all three extraction techniques, while the highest flavonoid yield was detected only in the mentioned methanolic extracts. The microwave reactor provided methanolic, ethyl acetate, and water extracts with the highest ABTS radical scavenging activity, while in the case of UAE, it was methanolic and water extracts, and in the case of MAC only water extracts. On the other hand, among lemon balm extracts from MAC, water extract possessed the highest ferric reducing power, whereas in UAE and MAE, it was ethyl acetate extract. Total tannin content determined in selected water extracts was 2.55, 4.53, and 1.83 mg tannic acid equivalent (TAE)/mL, while total proteins amounted to 1.34, 1.50, and 1.31 mg/mL using MAC, UAE, and MAE, respectively. The content of total extractive substances in the form of the extraction yield was also determined for selected water extracts and amounted to 12.6 % for MAC, 17.2 % for UAE, and 36.8 % for MAE. Further, this research has included the investigation of some physical properties of lemon balm water extracts, such as conductivity (3.68-4.14 mS/cm), pH (5.99-6.43), density (0.854-0.901 g/mL), surface tension (26.0-31.7 mN/m), and viscosity (1.18-1.21 mPa·s). This research represents the base for the future encapsulation of lemon balm extracts, enriched in polyphenol content, in a novel type of biofunctional carrier that potentially can be applied in the pharmacy, chemical industry, and biotechnics.

The experiment was conducted to assess the adaptability of Lemon balm in different ecologies of Ethiopia during 2017/2018 and also during the 2022/2023 cropping seasons. The RCBD design in four replications was used and two harvesting cycles were considered for evaluation of the performance of the lemon balm for agronomic and economic traits. Data on plant height, fresh leaf weight per plant, fresh stem weight per plant, fresh leaf-to-stem ratio, fresh leaf yield per hectare, and dry leaf yield per hectare were recorded and the recorded experimental data were statistically analyzed by analysis of variance (ANOVA) using SAS PROC GLM (2002) at P < 0.05. Differences between means were assessed using the least significance difference (LSD) test at P < 0.05. During the 2017/18 cropping season, ANOVA showed lemon balm performance varied significantly due to the harvest cycle and location. The first harvest cycle was superior in all traits considered for evaluation compared to the second harvest cycle. At the Debrezeit testing location there were very highly significant (p<0.001) results for fresh leaf weight per plant, fresh stem weight per plant, fresh leaf yield per hectare, and dry leaf yield per hectare except fresh to stem ratio. Similarly, the harvest cycle and location exerted significant variation during the 2022/2023 cropping season. The first harvest cycle was significantly higher in all traits again, while the Manche experimental site was significantly higher in dry leaf yield per hectare (2.83 tons per hectare). Therefore, the results of the current experiment showed that lemon balm can be produced in Ethiopia at various locations similar to the current testing site and we recommend the production of the existing lemon balm for similar agro-ecologies.

Lemon balm (Mellissa offisinalis L.) belongs to the Lamiaceae family with medicinal properties such as anti-bacterial anti-depressants anti-inflammatory, anti-cancer and anti-viral effects The most pharmacological effects of this plant are related to its active ingredient, rosmarinic acid In this research the effects of different concentration of elicitors yeast extract (0, 0.5 and 2 mg/mL D and copper (O. 4 8 and 16 HM) at different time intervals (4 8 and 16 h were investigated on rosmarinic acid and total flavonoid contents in 30-day-old seedlings of lemon balm greenhouse conditions Results showed a significant effect of yeast extract on rosmarinic acid production, especially after 4 and 8 hours of treatment with this elicitor. The highest amount of this compound was observed in seedlings treated with mg/mL of this elicitor. On the other hand. copper elicitor at all used concentrations and the duration time of treatment (except for 4 AM for 16 hours significantly increased rosmarinic acid production, SO that this elicitor at concentration of 8 HM for 8 hours treatment could induce rosmarinic acid level about 7-fold It seems that the elevated level of this active ingredient under treatment with these elicitors is due to the induction of reactive oxygen radicals and jasmonic acid biosynthesis and subsequently expression ofsome genes involving in rosmaric acid biosvnthesis

Eleven lemon balm (Melissa officinalis L.) populations originating from different sources in Turkey and European countries were investigated in two ecologically different locations, Menemen and Bozdaǧ, in the Aegean region of Turkey over three years to determine the populations having high quality and yield. There were significant variations between locations, years and populations in terms of yield and quality characters. The ecology was highly suitable in Menemen for growing lemon balm successfully and almost all yield and quality characters in Menemen were significantly higher than those in Bozdaǧ. The plant height, green herb yield, drug leaves yield and essential oil rate over populations and years were 47.58 cm. 2869 kg.ha-1, 496.9 kg.ha-1 and 0.067% respectively in Menemen while they were 20.73 cm. 416 kg.ha-1, 90.0 kg.ha-1 and 0.036% respectively in Bozdaǧ. The growth of populations in this study increased after the first year of the trials in both locations; therefore all yields were significantly higher in the second and third years of the trials compared to the first year. The populations numbered 9 and 7, originating from Germany and Romania, had high yield and quality and they were the two most promising populations for lemon balm cultivation in the locations studied. The green herb yield, drug leaves yield and essential oil rate of population 9 over three years at Menemen were 3389 kg.ha-1, 593.1 kg.ha-1 and 0.085% respectively while they were 2888 kg.ha-1, 565.1 kg.ha-1 and 0.097% respectively for population 7. The main component of the essential oil of the lemon balm was geranial in both locations and the average geranial rate was 38.13% in Menemen and 53.68% in Bozdaǧ. Hence, Menemen ecologic conditions were suitable for growing lemon balm with high yield and quality. Populations originating from Romania and Ege University Agricultural Faculty (Germany) are recommended to growers.

Nearly all cultures, from ancient times to today, have used plants as a source of medicine. In many developing countries, traditional medicine is still the mainstay of health care and most of the drugs and cures used come from plants. In developed countries many people are turning to herbal remedies. With this widespread use has come the assumption that plants identified as having medicinal qualities will be available on a continuing basis. However no concerted effort has been made to ensure this and in the face of the threats of increasing demand, a vastly increasing human population and extensive forest destruction, there can be no guarantee that we will continue to benefit indefinitely from this valuable resource. In light of this situation the World Health Organisation held a meeting in 1988. This book is the outcome of that meeting, detailing in a series of papers by leading experts the problems of which need to be addressed, the existing experiences from a range of countries and the future direction which must be taken to ensure the conservation of the world's medicinal plants.

The anti-HIV-1 activity of aromatic herbs in Labiatae was evaluated in vitro. Forty five extract from among 51 samples obtained from 46 herb species showed significant inhibitory effects against HIV-1 induced cytopathogenicity in MT-4 cells. In particular, the aqueous extracts of Melissa officinalis, a family of Mentha x piperita "grapefruit mint," Mentha x piperita var. crispa, Ocinum basilicum cv "cinnamon," Perilla frutescens var. crispa. f. viridis, Prunella vulgaris subsp. asiatica and Satureja montana showed potent anti-HIV-1 activity (with an ED of 16 mu g/ml). The active components in the extract samples were found to be water-soluble polar substances, not nonpolar compounds such as essential oils. In addition, these aqueous extracts inhibited giant cell formation in co-culture of Molt-4 cells with and without HIV-1 infection and showed inhibitory activity against HIV-1 reverse transcriptase.

Antioxidative compounds contained in the leaves of Melissa officinalis L. (lemon balm) were investigated. Six major compounds, protocatechuic acid (or 3,4-dihydroxybenzoic acid, 1), 2-(3',4'-dihydroxyphenyl)-1,3-benzodioxole-5-aldehyde (2), caffeic acid (3), rosmarinic acid (4), caffeic acid methyl ester (5), and rosmarinic acid methyl ester (6) were isolated from the extract of the plant and the 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity was measured. Among them, compound a showed the most potent activity, about ten-fold that of ascorbic acid and of a-tocopherol. The compound had a characteristic 1,3-benzodioxole structure and was easily degraded into two molecules of protocatechualdehyde.

Rosmarinic acid (RA), a naturally occurring extract from Melissa officinalis, inhibits several complement-dependent inflammatory processes and may have potential as a therapeutic agent for the control of complement activation in disease. Rosmarinic acid has been reported to have effects on both the classical pathway C3-convertase and on the cobra venom factor-induced, alternative pathway convertase. In order to define the mechanism of inhibition, the effect of RA on classical and alternative pathway lysis, C1q binding, the classical pathway convertase, the alternative pathway convertase, membrane attack pathway lysis and the generation of fragments of C3 and C5 during activation, was tested in vitro. The results showed that RA inhibited lysis by the classical pathway more than by the alternative pathway. This effect was dose-dependent with maximum inhibition of classical pathway lysis observed at 2.6 mmoles of RA. There was little effect on C1q binding or on the classical and alternative pathway convertases. However, there was highly significant inhibition of lysis of pre-formed EA43b cells by dilutions of human or rabbit serum in the presence of RA (1 mM); this was accompanied by inhibition of C5a generation. We conclude that the inhibitory effect of RA involves the C5 convertase. Such inhibition could be advantageous to the host in disorders where the terminal attack sequence plays a role in pathogenesis.
