目的提高苍耳草药材的质量控制标准。方法采用生药学常规方法进行性状鉴别、显微鉴别,建立薄层色谱鉴别方法;按《中国药典》一部附录方法,检查水分、总灰分、酸不溶性灰分、测定浸出物的含量。结果找到了苍耳草药材性状和显微鉴别特征;薄层色谱鉴别专属性强,重复性好;暂定苍耳草水分不得过14%,总灰分不得过17%,酸不溶性灰分不得超过2%,浸出物不得少于20%。结论所建标准能有效地评价苍耳草的质量。
Objective To improve the quality control standard of Kaleha herbs. Methods The traditional method of pharmacy was used to characterize and microscopic identification, and the identification method of TLC was established. According to an appendix of “Chinese Pharmacopoeia”, moisture content, total ash content and acid-insoluble ash content were determined and the content of extract was determined. The results showed that the characters of Kom. Herbaceous plants and the characteristics of microscopic identification were identified. The specificity of TLC identification was good and the repeatability was good. The tentative Xanthium should not exceed 14% moisture, total ash content 17%, acid insoluble ash content 2 %, Not less than 20% of extract.
