目的提取石榴皮、籽、花中的总黄酮并进行体外抗氧化能力的比较测定。方法以70%乙醇提取石榴皮、籽、花中总黄酮,采用直接显色法测定三者中总黄酮含量并测定石榴总黄酮对1,1-二苯基-2-三硝基苯肼(DPPH)自由基的清除能力、还原能力以及对羟自由基的抑制能力。结果1g石榴花中总黄酮含量为112.13mg,1g石榴皮中总黄酮含量为121.16mg,由于石榴籽与芦丁没有吻合的峰,故无法测量石榴籽中的黄酮含量。体外抗氧化实验中DPPH清除50%时所需要的石榴皮总黄酮的浓度为0.010 8mg/mL,石榴花总黄酮的浓度为0.015 1mg/mL。还原能力测定实验中,石榴皮总黄酮最大吸光度1.748,而同浓度维生素C仅为1.169;石榴花总黄酮最大吸光度1.732,维生素C为0.830;石榴皮总黄酮抑制能力对羟自由基抑制能力为355.7U/mL,同浓度维生素C溶液为273.2 U/mL,石榴花总黄酮为445.2 U/mL,同浓度维生素C溶液为239.1 U/mL。结论石榴皮中总黄酮含量>石榴花总黄酮含量。3个抗氧化试验结果显示石榴皮、石榴花总黄酮体外抗氧化能力为维生素C的2~3倍。
