摘要
目的:为充分利用红薯叶植物资源,避免资源的浪费,探讨红薯叶总黄酮的提取及鉴别方法。方法:采用超声波乙醇浸提法从红薯叶中提取黄酮类物质,对所提取的黄酮类物质进行验证,并用紫外分光光度法测定含量。结果:测得样品中总黄酮的含量C=19.50%,回收率为102.0%,其纯度和产率均较高。结论:该方法采用全物理过程,无任何污染,是提取红薯叶黄酮类物质的有效途径。
Objective： In order to make use of the resources of Ipomoea batatas Lam leaves, avoid wasting and approach the extraction of total flavanone of Ipomoea batatas Lain leaves. Methods ： The flavonids were extracted by ethanol as the solvent from Ipomoea batatas Lain leaves with ultrasonic wave and ethanol extraction, Using spectrophotometry to extract and check the flavanone of Ipomoea batatas Lain leaves Results： By this method getting the contents of the total flavanone of Ipomoea batatas L.am leaves is C = 19.50 96 and the rate of recovery is102.0 96. Conclusion ：This text provides the extraction and purifying methods to get the outcome and the purity of the flavanone are all very high , This method is a purely physical process, and has not any pollution. It is an ideal way to extract the flavanone of Ipomoea batatas Lam leaves.
