Abstract

Total antioxidant capacities, 2,2-diphenyl-1-picrylhydrazyl (DPPH·), hydroxyl (HO·), scavenging activities, and total phenolic values were determined in extracts of Cucurbita pepo L. female and male flowers. Powdered C. pepo L. samples were extracted in aqueous ethyl acetate (EA: W1, 17:3), ethanol (E), and water (W) by agitating in magnetic stirrer for 80°C, 15 min and also by in aqueous ethyl acetate (EA: W2, 17:3) at 25°C, 15 min. DPPH·, HO· scavenging capacities and total phenolic values of C. pepo L. female and male were higher in EA:W2 than in other extracts. In addition, all determined antioxidant capacities of female were significantly higher than male.
