Abstract: The alkaloids of Chinese medicine Qu's traditional medicine were separated after being developed with Chloroform:1,2-Dichloroethane:Methanol:Ammo-nia aqua (9:1:0.9:0.07) on silica gel G thin-layer plates The plates were colored by being sprayed with lmproved Dragendorff Reagent.And the aconitine spot was directly scanned and measured.The determination method was simple,rapid,sensitive and stable. This method makes possible for the quality control of Chinese composed medicine and the determination of aconitine content in some medicinal plants.

Key words: Thin-layer chromatography, Qu's traditional medicine, Aconitine

摘要： 在硅胶G薄层板上用氯仿:1,2-二氯乙烷:甲醇:氨水(9:1:0.9:0.07,v/v)为展开剂分离中草药复方曲氏传药中的生物碱,并用改良碘化铀钾试剂显色后对其中的乌头碱进行直接扫描测定。此法简便、快速、准确、灵敏且稳定。
