酸木瓜浸膏的抗氧化性研究

Study on Anti-oxidation Property of Extractum from Acidic Fuctus Chaenomeles

以酸木瓜为原料、乙醇-乙酸乙酯为溶剂,采用索氏提取法提取酸木瓜浸膏,通过L9(34)正交试验得出提取条件,同时对酸木瓜浸膏进行抗氧化性能研究。结果表明,影响酸木瓜浸膏得率的主要因素是溶剂比和温度,溶剂中乙醇的比例越高,浴温越高,浸膏的得率也越高。经不同方法提取浸膏的抗氧化性能结果显示:酸木瓜浸膏对猪油具有较明显的抗氧化作用,同时对·OH和DPPH·的清除率也较高。

To study the anti-oxidation property of extractum from acidic fructus chaenomeles,the extractum is extracted by solven soxhlet extraction method with acidic fructus chaenomeles as raw material and ethylacetateethanol as solvent. And the extraction conditions were analyzed by orthogonal experiment. The main influencing factors of extraction yield include solvent ratio and temperature. More extractums is get with more ethanol in solvent and higher bath temperature. The anti-oxidation property of extractum extracted by different methods show that all extractums have obvious antioxidant effect on lard oil,and have substantial scavenging efficiency to DPPH·and·OH.
