Introduction
Nowadays, cosmetics is intensively
used by both men and women as to treat
skin, improve the appearance and increase
the self-confidence in the community.
Lipstick is one kind of cosmetics products
which is used to care for and beautify lips.
This product is used intensively to keep the
colour in lips. Unconsciously, this behaviour
increases the possibility of its ingredients
to be consumed and accumulated. The
accumulation of chemical compounds in the
body can inict the serious health problems,
such as allergy, irritation, poisoning, tissue
damaging, cancer and death. The synthetics
chemical compounds are generally used as
colorant, preservatives and flavouring in
the ingredients of lipstick. According to this
problem, the production of lipstick using
safe ingredients from natural products is
being developed to maintain our health and
prevent the health problem.
Natural ingredients for cosmetics are
generally obtained from the plants and
fruits that contain the coloured compounds.
One of the natural ingredients for the
natural colorants is super red dragon fruit
(Hylocereus costaricencis). This dragon fruit
variety is known to have many benets for
health, such as the high antioxidant content
and antibacterial properties. According to
Abijeet (2012), super red dragon fruit could
be used as the additive in food, medicine
and cosmetics. However, the use of this fruit
for lipstick is limited. Moreover, the effect
of this fruit as antibacterial and antioxidant
is not much known. Through this study,
the potency of super red dragon esh will
be explored and developed in specic for
antioxidant and antibacterial. Its extract will
also be developed as a material for a herbal
lipstick.
Material and Methods
Samples
The materials in this study consists of
1 kg of super red dragon fruit (Hylocereus
costaricencis) aged 5 weeks, red colour and
fresh. Its rind has been separated from its
esh which give 600 g of its esh. The fruit
esh is the main component in this study.
Extraction of Super Red Fruit Dragon Flesh
Extraction is done in this study by
squeezing the fruit esh, then added 100 mL
aquadest and ltered to obtain the extract.

The half extract was evaporated using rotary
evaporator to obtain the crude extract,
whilst the half was used to the production
of lipstick. The yield was calculated using
Equation 1 (Eq.1).
%Yield = (Eq. 1)
Phytochemical Screening
The phytochemical screening was done
to detect the avonoid, saponin, tannin and
alkaloid compounds in the sample.
Flavonoid Assay
Zero point three (0.3) g of fruit esh
extract was placed in the test tube, then
added 3 mL n-hexane and shaken roughly
until producing no colour in the liquid.
Next, 20 mL ethanol 80% was added to the
liquid and divided into 3 parts. B1 solution
is a blank. B2 solution was added 0.5 mL
concentrated HCl then was heated on a
water bath. B3 solution was added 0.5 mL
concentrated HCl and 4 pieces of magnesium.
The changes of colour were observed. The
formation of orange solution shows the
content of avonoid (Sangi, Runtuwene and
Simbala, 2008).
Saponin Assay
Zero point three (0.3) g of fruit esh
extract was placed in the test tube, then
added 5 mL aquadest and shaken roughly
for 30 s. Positive result is shown by the
formation of stable bubbles on the surface of
the solution for 30 s.
Tannin Assay
Zero point three (0.3) g of fruit flesh
extract was placed in the test tube, then added
10 mL hot aquadest and homogenized. The
solution was left at the room temperature,
then added 3-4 drops of NaCl 10% and
homogenized. The solution was divided into
3 parts. C1 solution is a blank. C2 solution was
added 1-2 drops of gelation solution 1% and
5 mL NaCl 10%. The changes of colour were
observed. Tannin compound is indicated by
the formation of white sediment. If no colour
changes were found in C2 solution, 3 drops of
FeCl3 was added then observed. The formation
of green to orange colour indicates polyphenol
content. C3 solution was added 3 drops of
FeCl3, the formation of blackish green shows
tannin content.
Alkaloid Assay
Zero point three (0.3) g fruit esh extract
was placed in test tube, then added 5 mL HCl
2N. The solution was heated up for 2-3 min
while stirring, then was cooled down and
added 0.3 g NaCl and 5 mL HCl 2 N. Solution
was divided into 3 parts. Solution A1 is a
blank, Solution A2 was reacted with 3 drops
of Mayer reactant, solution A3 was reacted
to Wagner reactant. The colour changes, the
formation of precipitant and hazing solution
indicates alkaloid compound.
GC-MS Analysis
GC-MS analysis was done in LIPI Bogor. 1
g crude extract of dragon fruit was added 1 mL
dimethyl sulfoxide (DMSO) the homogenized
and placed in the ependorf. This sample then
was analysed using GC-MS instrument.
Antioxidant Activity Assays of Super Red
Dragon Flesh Extract
This assay was done for liquid extract of
dragon fruit using DPPH method (1,1-phenyl-
2-picrylhydrazyl). 19.71 mg of DPPH solid
was weighted and placed into the volumetric
ash. Then 50 mL methanol was added and
kept into the dark bottle. Blank solution was
incubated in room temperature 27oC for
30 min and wrapped with aluminium foil.
For comparing, 100 ppm ascorbic acid was
used, maximum absorbance was measured
at wavelength 510-520 nm. Sample was
calculated at 10, 20, 30, 40 and 50 ppm at 517
nm. Then, the graphic was plotted between %
inhibition versus concentration (ppm) which
would produce regression equation. IC50 was
calculated in µg/mL with y value equal to 50.
Lipstick Preparation
Eight (8) g of solid lipstick per batch
was made using active compound of super
red dragon fruit in the variation of crude
extract concentration (0, 10, 20, 30 and 40%).
The formulation of material for lipstick was
shown in Table 1.

Organoleptic Assays
The stability of each lipstick formula
was done for 3 weeks with the evaluation
every week. Lipstick was kept at 27°C and
37°C. Evaluation were done for the physical
appearance (formation of crystal and sweat),
smell and texture.
Peroxide Number Assays of Lipstick
Peroxide number is an indicator to
determine the level of oil damage or fat as
a result of oxidation reaction in the storage
condition. In this assay, peroxide number
was done for determine the antioxidant
concentration in the lipstick during storage.
Standardization of Na2S2O3 solution.
10 mL K2Cr2O7 was added to Erlenmeyer,
followed by 2.5 mL H2SO4 solution and 5
mL KI 20%. This solution was titrated with
Na2S2O3 using amylum as indicator. Titration
was performed until dark blue colour
disappearing. The concentration of Na2S2O3
was calculated.
Determination of Peroxide Number.
1 g lipstick was put into the Erlenmeyer
ask 50 mL, followed by the addition of 6
mL acetic acid glacial and 0.1 mL potassium
iodide saturated. Erlenmeyer was closed and
wrapped to prevent from the sun radiation,
and leaved it for 1 min while homogenized.
6 mL aquadest was added, the solution
was titrated with Na2S2O3 using amylum
as indicator until the dark blue colour
disappear. Peroxide number of lipstick was
determined using equation 2.

Antibacterial Assay
Antibacterial assay was done to know
the antibacterial activity of this compound to
Staphylococcus aureus bacteria. Bacteria was
cultured in to Nutrient agar medium (NA)
and nutrient broth (NB) and the number of
bacteria was calculated for 100 uL medium
each petri dish with pour plate method.
Plate was group in 4-5 zone to facilitate the
treatment. Then, the small holes were made
to put the sample. After the sample was put,
each petri dish was incubated in 37°C and
observed for 24 hours in aerobic condition
for S. aureus. The ability of antibacterial was
observed from the inhibition area which
was formed near the holes. The diameter of
inhibition area was measured. This assay was
done for the formulation of lipstick which
was stored for 1 and 3 weeks at either 27oC
or 37°C. This assay was also performed for
extract of super red dragon fruit and the
commercial lipstick.

have many activities such as antioxidant,
preservatives, additive, antimicrobial,
antibacterial, insecticide, fungicide and
nematicide.
Antioxidant Assay of Super Red Dragon
Fruit Extract
Antioxidant assay of extract was done
using DPPH method. From the assay, IC50
value of this extract was 81.55 µg/mL. The
correlation of % inhibition vs concentration
of extract was shown in Fig.3 for dragon
fruit extract and Fig. 4 for ascorbic acid as
standard.
Ascorbic acid has been known to have
antioxidant activity. In this study, we used
ascorbic acid as standard which has IC50 value
52.23 µg/mL. In the comparison of dragon
fruit extract with ascorbic acid, IC50 value of
the dragon fruit extract is 1.56 times higher
than ascorbic acid.
Organoleptic Assay of Dragon Fruit Lipstick
Organoleptic assay was performed to
obtain the information about the product’s
stability in texture, physical characteristic,
smell and colour. The dragon fruit lipstick
was made from several natural sources
such as beeswax, olive oil and peanut butter
which was mixed with dragon fruit extract
in different concentration. The physical
appearance of these lipstick was shown in
Fig. 5.
For the physical characteristics, we
observed the formation of crystal (C) or
no crystal (NC) and sweating (Sw) OR
no sweating (NSw). Then, for texture, the
product was soft (Sf) or rough (R). In the case
of smell, we smell that the product is fragrant
(F) or no fragrant (NF). For the colour, we
observed if the product is white (W), yellow
(Y), pink (P), light purple (LP) or dark purple
(DP). The result of organoleptic assay was
shown in Table 4.
Most formulation of lipsticks were
stable when were kept at 27°C for 3 weeks,
except F1 and F2 containing 10 and 20% of
crude extract respectively. After 1 weeks,
formation of crystal occurred for F1 and
F2 that changed their texture becoming
rough. The changes of colour happened in
all formulation during storage in different
time. The colour of F0 and F3 changes at 3rd
week, whereas F1 is stable. For F2 and F4,

could generate bad smell for the product
during the storage.
Peroxide number is a number of fatty
acid which could undergo oxidation process
or hydrolysis producing oxygen and peroxide
compound. Through this assay, we were also
able to know the antioxidant activity of super
red dragon fruit which reduces the bad smell
and taste. The result of peroxide number
assay was shown at Fig. 5 for storage at 27°C
and Fig. 6 for 37°C.
The peroxide number increased in all
formulations of lipstick during the storage
from 0 until 3 weeks. F0 showed signicant
increase of peroxide number. The highest
peroxide number was observed in F0 with
1.5 meq/kg for 27°C and 1.7 meq/kg for
37°C after observed for 3 weeks. The different
result was observed for F1-F5 at 27°C which
its peroxide number increased slightly.
In the assay of all formulations of
lipstick which were kept at 27oC or 37°C for
3 weeks, the peroxide number reduce along
with the increase of extract concentration
added into the formulation of lipstick. FI-
F5 contained the extract of dragon fruit
in different concentration, F5 contain the
highest concentration of extract. This result
showed that the higher concentration of
dragon fruit extract added in the formulation
of lipstick, the lower peroxide number of
the product which was related with the
antioxidant activity of the extract.
The temperature of storage also gives
an effect to the peroxide number of lipstick.
The result showed that the peroxide number
of all formulations at 37°C is slightly higher
than 27°C. It presents that the increase of
peroxide number is a result of the increase
of temperature.
Antibacterial Assay
Dragon fruit has been known as a
source of antibacterial. Based on Melliawati
(2009), antibacterial in super red dragon fruit
was able to overcome the infection of Staphy-
lococcus aureus. S. aureus is a gram-positive
bacterium which grows optimally at 37°C
and a normal ora which could be found
in skin, respiration system, gastrointestinal
and lips.
Ciprooxacin is an antibiotic used as
positive control. Based on the assay, positive
control in 1st or 3rd weeks of storage period
for 27o C or 37°C shows the high response
in the inhibition of the growth of S.aureus.
The extract of dragon fruit also represents
the inhibition of S.aureus growth in both 1st
and 3rd week of storage period. Then, for the
formulation of lipstick, F4 shows the positive
result for the inhibition of S.aureus, whereas
another formulation gives same result as
negative control even though it contains
extract of dragon fruit. In this study, we
observed that the inhibition activity of F4 is
higher than the extract itself.
Discussion
Secondary Metabolites in Super Red Dragon
Fruit
Extract of super red dragon fruit esh
contains many secondary metabolites that
have a lot of benets. Secondary metabolite
is an organic compounds that does not
have direct function for the growth and
development of plant but is needed for
the protection against biotic or abiotic
stresses and survivals (Pagare et al., 2015).
Through phytochemical screening, several
secondary metabolites such as avonoid,

lipstick for storage at 27°C. Figure 6. The peroxide number assay of dragon fruit
lipstick for storage at 37°C.

tannin and alkaloid have been detected in
this extract.
Flavonoids are the largest group of
naturally phenolics compounds isolated from
a wide range of vascular plant which act in
plant as visual attractors, photoreceptors, stress
protectants and for light screening (Pietta, 2000).
It also has some benets for human health such
as antioxidants, antimicrobials, antivirals,
antiallergenic and anti-inammatory (Pietta,
2000). Super dragon red fruit has red colour in
its esh and rind. According Harivaindaran
(2008), the colour pigment of super red
dragon fruit consists of anthocyanin, betalain,
betacyanin and betaxanthin. Anthocyanin is a
avonoid group with colour pigment from red
to blue. It has some biological activities such as
primary antioxidants, chelator and scavenger
for superoxide anion.
Moreover, tannin is also detected
in the dragon fruit extract. Tannin is a
phenolics compounds which have complex
structure, difcult to be separated and easy
to form crystal. Some studies observed the
biological activity of tannin as antioxidant,
antimicrobial, antitumor and anti-HIV
(Yoshizawa et al., 1987, Ho et al., 1999, Ho et
al., 2001, Lü et al., 2004, and Gu et al., 2008).
Other secondary metabolites in dragon
fruit is alkaloids. Alkaloids is a compound
that contain nitrogen atom in its structure.
Alkaloids functionates as antimicrobials,
antimalarial, cytotoxic and anti-HIV agents
(Ang et al., 2000, Iwasa et al., 2001, and
Samoylenko et al., 2009).
Through GC-MS analysis, some
secondary metabolites in dragon fruit
flesh extract have been detected. Some
compounds have antioxidant, antibacterial
and antimicrobial as shown in Table 3.
Antioxidant Activity of Super Red Dragon
Fruit
Antioxidant level of a compound is
represented by IC50 value. IC50 represents the
concentration of compounds that can prevent
and reduce the oxidation reaction in amount
of 50%. In this study, DPPH (1,1-diphenyl-2-
pycrilhydrazyl) method was used to measure
antioxidant activity. DPPH shows absorption
at wavelength 517 nm.
Some studies has observed the
antioxidant activity of dragon fruit. Fidrianny
et al. (2017), studied the antioxidant activity
of super red dragon fruit which obtained
IC50 value of ethyl acetate esh extract of
super red dragon fruit in 2.69 µg/mL. The
lowest IC50 indicates the highest antioxidant
activity. It could be categorized as a very
strong antioxidant.
In this study, the extract of super red
dragon fruit esh has IC50 value 81.55 µg/
mL. This value is higher than vitamin C
with IC50 value 52.23 µg/mL. Based on this
result, the antioxidant activity of extract of
super red dragon is still lower than vitamin
C. However, it can still be classied as strong
antioxidant activity.
Super red dragon fruit has antioxidant
activity because this fruit contains avonoids
compound which can bind to reactive
molecule or free radical species to prevent
oxidative reaction.
Evaluation of Super Red Dragon Fruit
Lipstick
Colour pigment from plant or natural
sources has been used in many kinds of
cosmetics, included the lipstick. According
to Aher et al. (2012), herbal lipstick from Bixa
orellana seeds had minimal or no side effect
which mostly arise in synthetic lipstick. In this
study, we developed a lipstick formulation
using the colour pigment from super red
dragon fruit with different concentration.
Then, the stability of lipstick was evaluated
in 2 different temperatures, 27oC and 37°C.
Our result showed that the storage at
27°C for this lipstick is better than 37°C. The
high temperature causes the evaporation
faster than low temperature in lipstick
formulation which promote the changes in
texture, physical appearance and colour. In
the case of formulation, lipstick with high
concentration of dragon fruit extract, F3
(30%) and F4 (40%), are more stable than
others when was kept at 27°C. No changes
of physical appearance, texture and smell for
F3 and F4 during evaluation 3 weeks, except
the colour. F3 was the most stable because
the changes of colour occurred lately at 3rd
week. In accordance with Purbaningtias
Sciscitatio, Vol. 1, No. 1, Januari 2020

Anjarsari et al.
et al. (2017), anthocyanins pigments (red,
purple and blue) are sensitive to the changes
of temperature, light exposure and pH. The
degradation of anthocyanins was inuenced
by the condition and storage period of the
sample.
Peroxide Number and Antibacterial Activity
of Herbal Lipstick
Lipstick contains oil and fatty acid
which can undergo hydrolysis or oxidation
causing rancid smell. The oxidation process is
affected by oxygen availability, light exposure,
high temperature, the kind of fatty acid, and
storage condition (Ketaren, 1986). In this study,
peroxide number assay was performed to
measure the number of fatty acid which can
undergo oxidation reaction. This assay used
iodometric titration for 3 weeks storage.
The result of this assay showed high
peroxide number in the lipstick formulation
without the dragon fruit extract (base
formulation) which was kept either at 27oC or
37°C. It was contrast to the base formulation,
lipstick formulation containing dragon
fruit extract had low peroxide number. It
represented that this esh extract possesses
antioxidant compounds encountering the
oxidative reaction. It was correlated with
the concentration of extract in the lipstick.
The higher concentration of extracts which
is added to the formulation, the lower
peroxide number that was detected. In GC-
MS analysis, several compounds having
antioxidant activity have been detected
(Table 3). According to Winarsi (2007),
antioxidant compounds are able to stop
oxidant reaction and the formation of free
radical molecules.
Apart from being antioxidant, super red
dragon fruit has also antibacterial activity.
According to Khalili et al. (2012), red pitaya or
dragon fruit esh and peel has have potential
against pathogenic food microorganisms,
gram positive or negative bacteria. For S.
aureus, the extract of red pitaya showed
high activity of inhibition with the inhibition
zones 19.00 ± 0.43 mm.
The extract of super red dragon fruit
flesh resulted the inhibition zones 14 mm
against S. aureus, whilst the ciprofloxacin
around 28 mm and F4 formulation which
was stored for 3 weeks at 27°C around 20
mm. It showed that F4 formulation stored
at 27°C has an antibacterial activity against
S. aureus. F1, F2 and F3 did not show any
inhibition caused by lower concentration
of extract. In the contrast with dragon
fruit lipstick F4, the commercial lipstick
did not show any antibacterial activity.
Inhibition zone which is higher or around
20 mm indicates the inhibition response of
S. aureus growth (Brooks, 2007). This result
corresponded to (Khalili et al., 2012), that red
dragon fruit esh has antibacterial activity,
in particular S. aureus. Then, based on the
study, storage temperature affected the
activity of compounds in the inhibition of S.
aureus growth. No antibacterial activity of
F4 lipstick formulation after stored at 37°C
for 3 weeks, whilst at lower temperature,
27°C, the antibacterial activity was still
high in F4 formulation. Although F1, F2,
and F3 have also contained the extract of
dragon fruit, no antibacterial activity has
been observed for these formulations at both
storage temperature. It represents that the
concentration of extract less than 40% in the
sample of lipstick could not inhibit the growth
of S. aureus effectively. The effect of storage
temperature needs to be studied in detail.
Conclusion
The extract of super red dragon fruit
flesh can be used as colorant in herbal
lipstick with storage period for 3 weeks at
27°C and 2 weeks at 37°C. The antioxidant
activity of this extract was 81.55 µg/mL. This
activity was also indicated by low peroxide
number of super red dragon fruit lipstick at
different concentration of extract. The best
formulation for this herbal lipstick was F4
formulation. This formulation showed the
high stability when was stored at 27oC for
3 weeks. Moreover, F4 formulation had an
antibacterial activity against S. aureus when
was kept at 27°C.

Background: Infectious diarrhoea is an emergent problem in both developing and developed countries for high rates of mortality in infants. In recent years, drug resistance to microbial pathogens has been commonly reported from all over the world. Medicinal plants represent a rich source of antimicrobial agents. Plants are used medicinally in different countries especially in India and are a source of many potent and powerful drugs. This study was aimed to explore the bioactive antimicrobial compounds present in Cinnamon zeylanicum, which is used as a spice in Indian foods. Objective: The aim of this study was to carry out Gas chromatography and Mass spectroscopy studies and to determine the antimicrobial activity of Cinnamon zeylanicum extract against some common microbial pathogens isolated from diarrhoeal patients. Methods: The extract was prepared by the method of maceration using methanol as extraction solvent. The antimicrobial activity was performed by disc diffusion method at the concentration 200, 100, 50, 25 and 10 mg/ml against E.coli, Salmonella typhi, Salmonella typhimurium, Shigella dysenterae, Shigella flexneri, Pseudomonas aeruginosa and Klebsiella pneumonia and the fungi Candida albicans, Candida tropicalis, Candida krusei which are isolated from the paediatric diarrhoeal samples. Gas chromatography and Mass spectroscopy studies were performed to identify the bioactive compounds. Results: The methanol extract was found very sensitive against all the isolated organisms. The preliminary phytochemical screening shows the presence of carbohydrate, glycosides, phenolic compounds, tannins, terpenes and proteins. The GC/MS study on the active principles shows the presence of 38 components. Conclusion: This study shows that the Cinnamon zeylanicum extract exhibit high antifungal activity as compared with antibacterial activity. The most identified compound by GC/MS to have antimicrobial property were monoterpenes, sesquiterpenes, aromatic aldehydes and ketones. Cinnamaldehyde was the major compound responsible for the antimicrobial activity.

Secondary metabolites (SM) are compounds that are not necessary for a cell (organism) to live, but play a role in the interaction of the cell (organism) with its environment. These compounds are often involved in plants protection against biotic or abiotic stresses. Secondary metabolites are from different metabolites families that can be highly inducible in response to stresses. Primary metabolites perform essential metabolic roles by participating in nutrition and reproduction. A few SMs are used as especially chemical such as drugs, flavours, fragrances, insecticides, and dyes and thus have a great economic value. These new technologies will serve to extend and enhance the continued usefulness of the higher plants as renewal sources of chemicals, especially medicinal compounds. A continuation and intensification efforts in this field is expected to lead to successful biotechnological production of specific, valuable and as yet unknown plant chemicals. © 2015 Current Trends in Biotechnology and Pharmacy.

Conjugated linoleic acid (CLA) is a group of geometrical and positional isomers of linoleic acid (C18:2, cis-9, cis-12). In contrast to linoleic acid, double bonds in CLA are usually located at positions 9 and 11 or 10 and 12 and each double bond can be either in the cis or trans configuration. Meat and dairy products from ruminant animals (such as milk, butter, yogurt and cheese) are the principal natural sources of CLA in the human diet. Egg and meat products from poultry contain less CLA than meat from ruminant animals (0.6 and 0.9 mg/g fat vs. 2.9 to 5.6 mg/g fat, respectively). Meat from turkeys contains much higher CLA relative to meat from chickens. Dietary CLA has been shown to have potent anticarcinogenic and antiatherogenic effects in animal models. CLA was also found to have a potent immune modulating activity characterized by increased blastogenesis and macrophage killing ability. In addition to these biological properties, CLA was reported to reduce body fat content and increase lean body mass in pigs and rodents. Because of these biological properties of CLA, recently there has been a lot of interest in enriching egg, meat and dairy products for human consumption.

Coloring skin particularly skin of face and lips is an ancient practice going back to prehistoric period. In present days the use of such product has increased and choice of shades of color, texture and luster have been changed and become wider. This can be observed from the fact that lipsticks are marked in hundreds of shades of colors to satisfy the demand of women. The present investigation was done to formulate herbal lipstick from Bixa Orellana seeds, since lipsticks are one of the key cosmetics to be used by the women. Due to various adverse effects of available synthetic preparation the present work was conceived by us to formulate a herbal lipstick having minimal or no side effects which will extensively used by the women of our communities with great surety and satisfaction. Attempt was also made to evaluate the formulated herbal lipstick and the F-IV was found better and accepted by female volunteers.

Cassia alata Linn is an important medicinal plant as well as ornamental flowering plant. The leaf decoction of Cassia alata has been used to treat infectious diseases in north eastern Nigeria. This study was embarked upon so as to evaluate the safety and efficacy of Cassia alata in the management of fungal infectious diseases. The leaves of the plant were collected, dried and extracted using water and 95% ethanol. The extracts were used for evaluating antifungal activity against five clinical isolates of pathogenic fungi. The result of this study showed a dose dependent antifungal activity of both aqueous and ethanolic leaf extracts on the five selected clinical isolates of pathogenic fungi. The extracts inhibited the growth of Candida albicans, Microsporum canis and Trichophyton mentagrophyte better than the ketoconazole 200 mg used as a positive control (p<0.05). The minimum inhibitory concentration of the water leaf extract of Cassia alata for Candida albicans, Aspergillus niger, Penicillium notatum, Microsporium canis and Trichophyton mentagrophytes were 26.90 mg, 32.40 mg, 29.50 mg, 30.30 mg and 27.80 mg respectively, while that of ethanol leaf extract of Cassia alata for Candida albicans, Aspergillus niger, Penicillium notatum, Microsporium canis and Trichophyton mentagrophytes were 5.60 mg, 3.50 mg, 4.90 mg, 12.60 mg and 9.80 mg respectively. Cassia alata has been found to exhibit a greater antifungal activity against some human pathogenic fungi in this study and this has justified the traditional use of this plant in managing fungal diseases.

The concept of using phytochemicals has ushered in a new revolution in pharmaceuticals. Naturally occurring polyphenols (like curcumin, morin, resveratrol, etc.) have gained importance because of their minimal side effects, low cost and abundance. Curcumin (diferuloylmethane) is a component of turmeric isolated from the rhizome of Curcuma longa. Research for more than two decades has revealed the pleiotropic nature of the biological effects of this molecule. More than 7000 published articles have shed light on the various aspects of curcumin including its antioxidant, hypoglycemic, anti-inflammatory and anti-cancer activities. Apart from these well-known activities, this natural polyphenolic compound also exerts its beneficial effects by modulating different signalling molecules including transcription factors, chemokines, cytokines, tumour suppressor genes, adhesion molecules, microRNAs, etc. Oxidative stress and inflammation play a pivotal role in various diseases like diabetes, cancer, arthritis, Alzheimer's disease and cardiovascular diseases. Curcumin, therefore, could be a therapeutic option for the treatment of these diseases, provided limitations in its oral bioavailability can be overcome. The current review provides an updated overview of the metabolism and mechanism of action of curcumin in various organ pathophysiologies. The review also discusses the potential for multifunctional therapeutic application of curcumin and its recent progress in clinical biology. Copyright © 2015. Published by Elsevier Ltd.
