摘要
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 degrees C, 15 min and also by in aqueous ethyl acetate (EA: W2, 17:3) at 25 degrees 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.
