藏药松生等的质量控制研究

Study on the Quality Standard of Tibetan Medicine Lignum rhamnellae

目的：建立藏药材松生等的质量标准。方法：采用显微鉴别、薄层鉴别，并参照2010年版《中国药典》附录对松生等药材的水分、灰分、酸不溶性灰分及醇溶性浸出物进行测定。结果：不同产地的藏药材松生等显微特征一致，薄层色谱重现性好、专属性强，水份为5.05％～7.55％，总灰分为1.05％～7.77％，酸不溶性灰分为0.08％～0.61％，醇溶性浸出物的结果为5.41％～17.21％。结论：该方法可作为控制传统藏药材松生等的质量标准。

Objective In order to establish the quality standards of Tibetan medicine Lignum rhamnellae.Methods Microscope was used to observe the plant organization structure and microscopic characteristics of powder;TLC was applied to identify the effective components qualitatively;The tests of water content,ash and ethanol -soluble extractives of Lignum rhamnellae were carried out ac-cording to the methods recordedin appendix of Chinese Pharmacopeia （2010 edition,volume 1）.Results The microscopic and TLC i-dentification methods were specific and well repeatable.The moistures in Lignum rhamnellae was 5.05% -7.55%,with the total ash within 1.05% -7.77%,the ethanol extract was 5.41% -17.21% by hot soak.Conclusion The methods could be used for the quali-ty control of Tibetan medicine Lignum rhamnellae.
