The study was aimed to evaluate phytochemical composition, antioxidant and antibacterial properties from powder of various underutilized fruits. Antibacterial activities from extracts of the underutilized parts of various fruit samples against Gram+ve (Staphylococcus aureus) and Gram-ve (Escherichia coli) bacteria were determined by using ELISA reader and expressed as relative inhibition (%), antioxidant profiles by ß-carotene and linoleic acid and ferric thiocyanate reducing ability. The phytochemical screening was done by standard methods and their composition revealed total phenols ranging from 119.5 (stone apple) to 139.0 (acacia, mg GAE/g). Mango waste (156 mg QE/g) contained the maximum amount of flavonoids while stone apple waste (13 mg QE/g) showed the least. Maximum and minimum amount of proanthocyanidins were shown by grape waste (468 mg CE/g) and mosambi waste respectively. Grape and acacia waste powder showed the highest reducing power while least amount of reducing power was observed in apple waste sample. The waste powders from stone apple and orange exhibited potent antibacterial activity against microorganisms tested. Study revealed strong antioxidant profiles in acacia fruits and antibacterial activity in stone apple and orange. [ABSTRACT FROM AUTHOR]
