摘要:

用Na2S2O3-I2 滴定法测定了天山堇菜提取物对猪油的抗氧化作用。结果表明,不同溶剂天山堇菜提取物对油脂均有一定的抗氧化性,强弱顺序是:85% 的乙醇提取物的抗氧化活性>丙酮提取物>氯仿提取物>乙酸乙酯提取物>无水甲醇提取物>正己烷提取物,且提取物用量与抗氧化性呈正相关系。同时与VE 和VC 进行比较,0.5%(W/V)的85%乙醇提取物的抗氧化性强于0.02%(W/V)VC,而0.02% (W/V)VE 的抗氧化活性很小。

Abstract:

Antioxidative Activity of Extracts from Viola tianshanica Maxim. was measured by Na2S2O3-I2 titrimetric method. The results showed that the antioxidative activities decreased in the order of 85% ethanol solution extracts > acetone extracts > chloroform extracts > ethyl acetates extracts> methanol anhydrous extracts >n-hexane extracts.The amount of extracts used is directly inproportion to the anti-oxidative effect.When the control experiment was performed by using VC and VE, it is showed that 85% ethanol solution extracts of Viola tianshanica Maxim.(0.5%W/V) have stronger antioxidant activity than 0.02%VC(W/ V), but 0.02%VE(W/V) have no antioxidant activity.

Key words: Viola tianshanica Maxim, extracts, antioxidantive activity
