摘　　要：以马齿苋、苦瓜和仙人掌3种蔬菜为材料,微波提取黄酮化合物,通过芦丁标准曲线法测定提取液中的黄酮化合物含量,利用DPPH法测定提取液的抗氧活性,结果表明:3种蔬菜都含有黄酮化合物分别为:马齿苋19.48%,苦瓜13%,仙人掌5.82%。其抗氧活性分别为:马齿苋73.27%,苦瓜51.47%,仙人掌25.48%。其黄酮化合物含量多少与抗氧活性强弱顺序一致:马齿苋>苦瓜>仙人掌。由此可见3种蔬菜的抗氧活性与黄酮类化合物含量有直接的关系。From purslane,bitter melon and cacti,flavonoid was extracted by microwave,its contents were made using rutin standard curve and the antioxidant activities were determined by DPPH method.The results indicated that flavonoids in purslane,bitter melon and cacti are 19.48 %,13 % and 5.82 %,respectively.And the antioxidant activities in the three vegetables are 73.27 %,51.47 % and 25.48 %,respectively.There was a positive correction between content of flavonoids and antioxidant activity.Three plants showed the following trends： purslane 〉 bitter melon 〉 cacti.
