何首乌浸出物测定方法初探及不同产地不同种植年限何首乌浸出物含量比较

Determination of Polygonum multiflorum extraction,and extraction content comparison from different places in different cultivation age Polygonum multiflorum

目的:为修订何首乌质量标准积累数据。方法:选择水及不同浓度乙醇作浸出溶剂,结合热浸、冷浸等实验进行方法考察,并对不同产地、不同种植年限何首乌浸出物进行检测。结果:采用50%乙醇冷浸法浸出物含量最高;不同产地及不同种植年限何首乌浸出物含量存在一定的差异。结论:该方法简单、准确、重复性好,为何首乌质量标准的修订提供了科学实验数据。

Objective：To establish a extract method of determining the quality of a comprehensive evaluation of polygonum multiflorum. Methods：Water and different concentrations of ethanol as extraction solvent,combined with hot dip,cold soak method of examining such experiments,and different places in different cultivation age polygonum multiflorum extract for testing. Results：The cold soak method with 50% ethanol extract of the highest content of different areas and different cultivation age polygonum multiflorum extract there were some differences in content. Conclusion：The method is simple,accurate,reproducible,and can provide a scientific experiment data for fleece-flower root quality standards amendments.
