目的:建立羊耳菊的质量标准。方法:参考2015年版《中国药典》方法,对羊耳菊药材的质量控制方法进行研究,包括薄层色谱定性鉴别、水分检查、总灰分、酸不溶灰分检查和浸出物检查。结果:15批羊耳菊药材的TLC图斑点清晰,分离度良好;药材水分含量为9.79%~15.76%,平均值为11.00%;总灰分含量为4.05%~6.66%,平均值为5.43%;酸不溶性灰分含量为0.40%~2.76%,平均值为1.69%;浸出物含量为8.96%~14.71%,平均值为10.80%。结论:以东莨菪内酯为对照品的定性方法操作简单,稳定性和重复性良好,可用于羊耳菊药材的质量控制。
Objective: To establish the quality standard of Myrica rubra Methods: With reference to the 2015 edition of “Chinese Pharmacopoeia” method, the quality control methods of Pleurotus ostreatus were studied, including qualitative identification by thin layer chromatography, water test, total ash, acid-insoluble ash test and extract check. Results: The TLC pictures of 15 medicinal materials were clear and the resolution was good. The moisture content of herbs was 9.79% ~ 15.76% with the average value of 11.00%. The total ash content was 4.05% ~ 6.66% with the average value of 5.43%. Acid insoluble ash content of 0.40% ~ 2.76%, an average of 1.69%; extract content of 8.96% ~ 14.71%, with an average value of 10.80%. Conclusion: Scopolactone as reference substance of the qualitative method is simple, stable and reproducible, and can be used for quality control of medicinal Herbs.
