An investigation was conducted to extract polyphenols from moringa leaf, tamarind seed, mint and lemongrass for the development of functional date bars. Solvent methanol, ethanol acetone at 50% 75% concentration employed extraction through ultrasound assisted technique.Higher flavonoids were extracted leaf with comparatively more antioxidant activity than other herbs studied. Date bars fortifie...

Cocoa is a rich source of high-quality antioxidant polyphenols. They comprise mainly catechins (29%-38% of total polyphenols), anthocyanins (4% of total polyphenols) and proanthocyanidins (58%-65% of total polyphenols). A growing body of experimental and epidemiological evidence highlights that the intake of cocoa polyphenols may reduce the risk of cardiovascular events. Beyond antioxidant prop...

An experimental setup based on a 2(3) full-factorial, central-composite design was implemented with the aim of optimising the recovery of polyphenols from olive leaves by employing reusable and nontoxic solutions composed of water/ethanol/citric acid as extracting media. The factors considered were (i) the pH of the medium, (ii) the extraction time and (iii) the ethanol concentration. The model...

Freeze drying was compared with spray regarding feasibility to process wild thyme drugs in order obtain dry formulations at laboratory scale starting from liquid extracts produced by different extraction methods: maceration and heat-, ultrasound-, microwave-assisted extractions. Higher total powder yield (based on the weight prior extraction) achieved freeze than lower loss of polyphenol conten...

An investigation was carried out to extract polyphenols from mango and kinnow mandarin peels for the development of functional fruit bars their storage stability. Solvent ethanol at 50%, 80% 100% concentration employed extraction through ultrasound assisted technique. Higher were extracted with comparatively more antioxidant activity than peels. Fruit fortified different levels peel polyphenoli...

flavonoids, are a large class of polyphenols, with more than 4000 combinations. they have an antioxidant role in plant photosynthesis and in the human body they optimally act as an antioxidant, anti-inflammatory, anticancer and protector of the heart. quercetin is in the flavonol group that is used to fight protection specifically against viruses and cancer cells. in this study, comparison of e...

BACKGROUND 6-Gingerol is one of the most pharmacologically active and abundant components in ginger, which has a wide array of biochemical and pharmacologic activities. In recent years, the application of microwave-assisted extraction (MAE) for obtaining bioactive compounds from plant materials has shown tremendous research interest and potential. In this study, an efficient microwave-assisted ...
