野生食用蔬菜甜菜树的抗氧化活性研究

Antioxidant Activity of Wild Edible Vegetable Yunnanopilia longistaminata

采用DPPH法对民间野生食用蔬菜植物甜菜树提取物的体外自由基清除作用进行了研究。结果表明野生食用蔬菜甜菜树具有一定的抗氧化活性,不同提取物自由基清除作用差别较大,以乙酸乙酯提取物活性较好,但均较BHA和VC弱。

The antioxidant activities of the petroleum ether, EtOAc, BuOH and H2O extracts of Yunnanopilia longistaminata （W.Z.Li） C.Y.Wu ＆ D.Z.Li, which is used as a wild edible vegetable in folk, were studied by the DPPH radical scavenging activity method. All the extracts exhibit weak scavenging activities on DPPH radical. The EtOAc extract and the BuOH extract exhibit relative good scavenging actions than the others, but their actions are much lower than that of BHA and VC, respectiveiy.
