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.
测定了西葫芦雌花和雄花提取物的总抗氧化能力、2,2-二苯基-1-苦基肼（DPPH·）、羟基（HO·）清除活性以及总酚含量。将西葫芦粉末样品在80℃下于磁力搅拌器中用乙酸乙酯水溶液（EA:W1，17:3）、乙醇（E）和水（W）搅拌提取15分钟，同时也在25℃下用乙酸乙酯水溶液（EA:W2，17:3）搅拌提取15分钟。西葫芦雌花和雄花的DPPH·、HO·清除能力以及总酚含量在EA:W2中高于其他提取物。此外，所测定的雌花的所有抗氧化能力均显著高于雄花。
