Abstract
Quince is the rich source of metabolites with interesting biological properties. In vitro antioxidant capability of methanolic extract of the different fractions of quince (peel, pulp seeds and mucilage) was evaluated by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, Total phenolics, Reducing power, FRAP value and H2O2 scavenging activities. The results obtained for DPPH (43.20%-69.40%), TPC (41.23 mg GAE/100 g-97.51 mg GAE/100 g) RP (31.90%-74.40%) FRAP (0.63 µM-1.16 µM) and H2O2 activity (14.2%-34.2%) revealed a significant difference in antioxidant properties among fractions. The results indicate that peel and seeds which otherwise are wasted, are effective in scavenging free radicals and can serve as potential antioxidants.
