【摘要】 目的为充分利用野菊花植物资源,避免资源的浪费,探讨野菊花总黄酮的提取及鉴别方法。方法采用超声波乙醇浸提法从野菊花中提取黄酮类物质,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=0.6599 mg/m l,回收率为101.1%,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,是提取野菊花黄酮类物质的有效途径。更多还原

【Abstract】 Objective To make use of the resources of Chrysanthermum indicum L.,avoid wasting and approach the extraction of total flavanone of Chrysanthermum indicum L..Methods The flavonoids were extracted by ethanol as the solvent from Chrysanthermum indicum L.with ultrasonic wave and ethanol extraction.Using spectrophotometry to extract and check the flavanone of Chrysanthermum indicum L.Results The density of the total flavanone of Chrysanthermum indicum L.was C=0.6599 mg/ml and the rate of recovery was 101.1%.The 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 Chrysanthermum indicum L..更多还原
