摘　　要：目的:对景天三七的质量标准进行研究,着重建立景天三七药材的TLC定性鉴别方法以及对不同批次景天三七的水分、灰分、浸出物进行测定。方法:依据2015版《中国药典》中相关检测方法,对9批次不同产地的景天三七的水分、灰分、浸出物进行检测;采用硅胶GF254薄层板以氯仿—乙酸乙酯—甲酸(5∶5∶1)为展开剂,薄层扫描仪紫外365 nm下摄像,建立景天三七药材的TLC定性鉴别方法。结论:建立了景天三七药材的TLC鉴别方法,并对景天三七的水分、灰分、浸出物进行了测定,可用于完善现行药材质量标准,有效控制景天三七药材的质量。Objective: To establish its TLC method for the qualitative identification of Sedum aizoon and determine the water content, ash content and extract of different batches. Methods: According to the relevant detection methods in Chinese pharmacopoeia(2015), the water content, ash content and extracts of ten batches Sedum aizoon from different areas were detected. TLC identification was established by using silica gel GF254 and chloroform/ethyl acetate/formic acid(5∶5∶1) as the developing agent. Conclusion: TLC identification method of Sedum aizoon was established. Besides, the water content, ash content and extract of Sedum aizoon were measured, which can be used to improve its quality standard.
