【摘要】 目的为充分利用马鞭草植物资源,避免资源的浪费,探讨马鞭草总黄酮的提取及鉴别方法。方法采用超声波乙醇浸提法从马鞭草中提取黄酮类物质,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=0.2028 mg/ml,回收率为101.4%,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,是提取马鞭草黄酮类物质的有效途径。更多还原

【Abstract】 Objective To make use of the resources of herba verbenae,avoid wasting and approach the extraction of total flavanone of herba verbenae.Methods The flavonoids were extracted by ethanol as the solvent from Herba Verbenae with ultrasonic wave and ethanol extraction.Using spectrophotometry to extract and check the flavanone of Herba Verbenae.Results The density of the total flavanone of herba verbenae was C=0.2028 mg/ml and the rate of recovery was 101.4%.Tthe outcome and the purity of the flavanone were all very high.Conclusion This method is a purely physical process and has not any pollution.It is an ideal way to extract the flavanone of Herba Verbenae.更多还原
