TIC chromatogram of the fix oil from seeds of Nelumbo nucifera.
Source publication
In the present study, chemical composition of fixed oil (NnFO) obtained from Nelumbo nucifera seeds was determined by GC-MS analysis which revealed the presence of 39 compounds mainly comprised of 20.8 % keto fatty acids with high content of methyl ester of palmitic acid (13.59 %) and methyl ester of 9-oxo-nonanoic acid (11.89 %). The other major c...

Berane Basin in Montenegro has been known for rich paleoflora of diverse
geological ages. The remains of paleovegetation of various ages were
preserved by the lake occurring in this area from Late Oligocene to Early

be easily followed by studying the paleofloras collected a...
Dietary fibre is an essential component of the diet. Several components and ingredients can be used as a source of fibre and this study is aimed at using carrot pomace and lotus stem as a major substitute. Carrot pomace is the by-product obtained during carrot juice extraction process. It is rich in fibre and contains good amounts of carotenoids an...

Flavanone 3-hydroxylase (F3H) converts flavanones from dihydroflavonols, which leads to production of flavonoid compounds via the anthocyanin biosynthesis pathway in plants. In this study, the F3H gene was isolated from lotus (Nelumbo nucifera Gaertn.) cv. Buntharik (white petal lotus), cv. Satabankacha (pink petal lotus), and waterlily (Nymphaea s...
Sacred lotus (Nelumbo nucifera Garten.) is one of the most popular cut flower in Thailand for long time, since its flower related to Buddhism ceremony. However, the plant had limited for year round production when it came to dormancy in winter. Lead to less floral product in the market. This study was aim to clarify the effect of gibberellins acid...

... Many studies have demonstrated that plant-derived natural compounds or essential oils (EOs) exhibit antifungal and antiaflatoxigenic activities against A. flavus. Many previous studies were conducted in vitro using direct-contact antimicrobial assays [10][11][12][13][14][15]. Some plantderived natural compounds have been similarly tested on food materials, such as corn, wheat, soybean, chickpea, pistachio, peanut, and rice ( Table 1). ...
Aspergillus flavus is a facultative parasite that contaminates several important food crops at both the pre- and post-harvest stages. Moreover, it is an opportunistic animal and human pathogen that causes aspergillosis diseases. A. flavus also produces the polyketide-derived carcinogenic and mutagenic secondary metabolite aflatoxin, which negatively impacts global food security and threatens human and livestock health. Recently, plant-derived natural compounds and essential oils (EOs) have shown great potential in combatting A. flavus spoilage and aflatoxin contamination. In this review, the in situ antifungal and antiaflatoxigenic properties of EOs are discussed. The mechanisms through which EOs affect A. flavus growth and aflatoxin biosynthesis are then reviewed. Indeed, several involve physical, chemical, or biochemical changes to the cell wall, cell membrane, mitochondria, and related metabolic enzymes and genes. Finally, the future perspectives towards the application of plant-derived natural compounds and EOs in food protection and novel antifungal agent development are discussed. The present review highlights the great potential of plant-derived natural compounds and EOs to protect agricultural commodities and food items from A. flavus spoilage and aflatoxin contamination, along with reducing the threat of aspergillosis diseases.
