摘要
采用Schaal烘箱法,以过氧化值(POV)为评价指标,比较了甘草、淫羊藿、黄芪、黄芩、连翘5种中草药乙醇提取物对猪油的抗氧化作用效果。结果表明,5种中草药乙醇提取物抗氧化活性存在一定差异,表现为甘草>黄芪>黄芩>淫羊藿>连翘。总体上5种中草药乙醇提取物均可有效延缓猪油的氧化反应,且5种提取物在0.1%～0.3%添加量范围内其抗氧化能力随添加量的增加而增强,呈现一定的量效关系。
POV was used as an index,and the antioxidative activities of five ethanol extracts from Chinese herbal medicine including Licorice, Epimedium, Astragalus, Huangcen and Forsythia to the lard were compared by Sehaal oven - storage test. The results showed that the antioxidative activities of five extracts were different, and their sequences were： Licorice 〉 Astragalus 〉 Huangcen 〉 Epimedium 〉 Forsythia. However, five ethanol extracts could prevent the oxidative reaction of lard, and the positive correlation existed between antioxidant capacity and extracts contents within the concentration of 0.1% - 0.3%.
