摘要: 用Na2S2O3-I2滴定法测定了厚朴提取物对猪油的抗氧化作用。结果表明:乙酸乙酯提取物的抗氧化活性>60%乙醇提取物>95%乙醇提取物>正己烷提取物>水提取物。提取物用量与抗氧化性呈正相关。柠檬酸、酒石酸、抗坏血酸及VE对它有一定的协同增效作用,若两种以上增效剂合用,则协同增效作用更为显著。

Abstract: Antioxidative effects of extracts of Officinal Magnolia on lard were measured by Na2S2O3-12 titrimetric method.The results show that the antioxidative activities decreased in the order of ethyI acetates extracts > 60% ethanol solution extracts >95% ethanol solution extracts > n-hexane extracts > pure water extracts.The usage of extracts is in directly prportion to the antioxidative effect. Citric acid.tartaric acid,ascorbic acid and α -tocopherol show synergistic antioxidative activities with extracts of Officinal Magnolia.When two of these (Citric acid,tartaric acid.ascorbic acid and α -tocopherol )were used together with Officinal Magnolia extracts of Officinal Magnolia. strong synergistic action was showed.

Key words: Officinal Magnolia extract Synergistic antioxidative activity
