摘要
目的:测定云连药材的水分、灰分和浸出物,为建立云连药材质量标准提供依据。方法:按《中国药典》2010年版一部附录IX H中水分测定法中的第一法、附录IX K灰分测定法和附录X A浸出物测定法测定。结果:云连药材含水量不超过14.00%,总灰分不高于5.00%,酸不溶性灰分不高于(1.78±0.04)%,热浸法水溶性浸出物量不低于(24.42±0.25)%,热浸法醇溶性浸出物量不低于15.00%,挥发性醚浸出物含量不低于(3.39±0.08)%。结论:该方法简单、准确、重复性好,为建立云连药材质量标准提供了依据。
Objective： To determine the moisture,ashes,and extracts from the Coptidis rhizome for establishing the quality standards.Methods： According to the procedures recorded in the Appendix IX H,IX K and X A of 2010 Chinese Pharmacopoeia,moisture,ashes,and extracts of samples were measured respectively.Results： The moisture of Coptidis was less than 14.00%;the total ashes was less than 5.00 %,with the acid insoluble ash content was less than（1.78±0.04）%;with hot soak method,the content of water extract was higher than（24.42±0.25）%,the content of ethanol extract was not less than 15.00%,the content of ether extract was higher than（3.39±0.08）%.Conclusion： The methods discribed above are simple,accurate and replicatable.They are suitable for moisture,ashes and extracts measurement.
