摘要:  不同方法提取银杏叶中的抗氧化物质,以食用菜油和猪油作底物,用烘箱贮藏法测定抗氧化活性。结果表明:石油醚-乙醇提取法得到的提取物抗氧化作用最强,其次是80%乙醇提取物,水提取物的效果最差。同时对不同方法的提取率进行了比较。

Abstract: Extracts of the leaves of Ginkgo biloba were got by different extracting methods.The activities of oxidation resistance ofthe extracts were measured by rape oil and lard as substrates.It was found that the extract obtained by petroleum ether-ethanolextracting method showed the highest activity;ethanol extract was next:water extract showed poor results.Furthermore.the yieldsof the extracts obtained by different methods were compared.
