Background: Cucurbita maxima known as pumpkin belongs to the family Cucurbitaceae, widely used in traditional medicine. Methods: The present work evaluates antioxidant activity of different parts (leaves and fruit) maxima. Antioxidant was assessed through DPPH test β-carotene bleaching test. Result: results showed that ethanolic extract fruit leaves are rich polyphenols, flavonoids tannin with ...

The proanthocyanidins or condensed tannins, phenolic polymers which are synthesized by many plants, characteristically bind and precipitate proteins. The specificity of the interaction was investigated using a competitive binding assay to compare directly the affinities of various proteins and synthetic polymers for the tannin obtained from Sorghum bicolor (Lin.) Moench. At pH 4.9, the relative...

The antibacterial activities of hexane, ethyl acetate, acetone, ethanolic, methanolic and aqueous extracts of Mangifera indica kernel were studied in vitro against aquatic pathogens viz. Aeromonas hydrophila (six strains), Pseudomonas putida (three strains), P. aeruginosa (three strains), P. fluorescens (two strains), Flavobacterium columnare (three strains), Vibrio parahaemolyticus (two strain...
