目的制定青蒿叶药材的质量标准,为该药用植物资源的开发利用提供科学依据。方法采用了显微鉴别法、薄层色谱法、HPLC、水分测定法、灰分测定法及浸出物测定法。结果根据10个不同产地青蒿叶测定结果,确定青蒿素含量不低于0.1%,东莨菪内酯含量不低于0.1%,含水分不高于11%,总灰分不高于11%,酸不溶性灰分不高于2%,95%乙醇冷浸出物不低于7%。结论建立了青蒿叶的质量标准。
Objective To establish the quality standard of Artemisia annua L. leaves and provide a scientific basis for the exploitation and utilization of the medicinal plant resources. Methods Microscopic identification, TLC, HPLC, moisture determination, ash determination and extract determination were used. Results According to the determination results of Artemisia annua leaves in 10 different producing areas, the content of artemisinin was not less than 0.1%, the content of scopoletin not less than 0.1%, the content of water not more than 11% and the total ash not more than 11% Acid insoluble ash is not higher than 2%, 95% ethanol cold extract not less than 7%. Conclusion The quality standard of Artemisia annua leaves was established.
