摘要
目的为充分利用车前草植物资源,避免资源的浪费,探讨车前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车前草中提取黄酮类物质,对所提取的黄酮类物质进行验证,并用紫外分光光度法测定含量。结果测得样品中总黄酮的含量为1.24%,平均回收率为103%,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,是提取车前草黄酮类物质的有效途径。
Objective In order to make use of the resources of plantago seed and avoid wasting, approach the extraction of total flavanone of herba plantaginis. Methods The flavonoids were extracted by ethanol as the solvent from herba plantaginis with ultrasonic wave and ethanol extraction. Using spectrophotometry to extract and check the flavanone of herba plarttaginis. Results By this method getting the contents of the total flavanone of herba plantaginis is 1.24% and the average rate of recovery is 103%. Conclusion This text provides the extraction and purifying methods to get the outcome and the purity of the flavanone is very high. This method is a purely physical process, and has not any pollution. It is an ideal way to extract the flavanone of herba plantaginis.
