摘　　要：目的:为充分利用榕树叶植物资源,避免资源的浪费,探讨榕树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榕叶中提取黄酮类物质,并对所提取的黄酮类物质进行验证,用分光光度法测定其含量。结果:测得样品中总黄酮的含量C=1.9392mg/ml,回收率为102.7%,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,是提取榕树叶黄酮类物质的有效途径。Objective： In order to make use of the resources of banyan leaves , avoid wasting and approach the extraction of total flavanone of banyan leaves. Methods： The flavonids were extracted by ethanol as the solvent from banyan leaves with ultrasonic wave and ethanol extraction. Using spectrophotometry to extract and check the flavanone of banyan leaves. Results. By this method getting the density of the total flavanone of banyan leaves is C= 1. 9392mg/ml and the rate of recovery isl02.7%. 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 banyan leaves.
