The Total Flavanone of Gendarussa Ventricosa Extraction and the Identification by Ultrasonic Wave

目的:为充分利用大驳骨植物资源,避免资源的浪费,探讨大驳骨总黄酮的提取及鉴别方法。方法:采用超声波乙醇浸提法从大驳骨中提取黄酮类物质,对所提取的黄酮类物质进行验证,并用分光光度法测定含量。结果:测得样品中总黄酮的含量C=0.1230 mg/ml,回收率为99.05%,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,是提取大驳骨黄酮类物质的有效途径。

Objective： In order to make use of the resources of gendarusse ventricosa, avoid wasting and approach the extraction of total flavanone of gendarusse ventricosa. Methods ： The flavonids were extracted by ethanol as the solvent from murraya kwangsiensis with ultrasonic wave and ethanol extraction . Using spectrophotometry to extract and check the flavanone of gendarussa ventricosa. Results： By this method getting the density of the total flavanone of gendarussa ventricosa is C= 1,0128 mg/ml and the rate of recovery is 99. 05 %. 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 gendarussa ventricosa.
