Evaluation of Antioxidant Activity of Solvent Extracted Pomegranate Peel and its Effect against Plant Pathogenic Bacteria and Fungi

摘要

Pomegranate peel the byproduct of pomegranate industry when extracted with different solvents revealed that methanol: water (80:20) and acetone: water (80:20) to be equally effective solvents for extraction of various antioxidants. The peel extract ofGanesh variety of pomegranate had more amount of antioxidant viz., phenol, proathocyanidin and flavonoid with more antioxidant activity in terms DPPH and FRAP value when compared with the synthetic butylated hydroxyl toluene (BHT). The methanolic extract when tested against different plant pathogens viz., Xanthomonas spp.( Xanthomonas axonopodis pv. punicae, Xanthomonas axonopodis pv. malvacearum and Xanthomonas axonopodis pv. citri), Aspergillus flavous and Fusarium oxysporum f.sp. ciceri was found toinhibit the growth of bacteria and fungi.
