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 of Ganesh 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 to inhibit the growth of bacteria and fungi.
