%X The active components of dl-tetarohydropalmatine can be separated from the crude extract of corydalis yanhusuo W.T.Wang in the process of one-step elution by the technology of high-speed countercurrent chromatography.The binary system of its solvents consists of petroleum ether-ethyl acetate-methanol-the quarternary system of water with the stationary phase as its upper layer and the mobile phase as its lower layer,850r/min as the operational speed of the instrument used and 1.2ml/min as the flow speed of the solvents.The chemical structure of the separated dl-tetrahy-dropalmatine is confirmned through the identification of EI-MS and IH-NMR and its purity reaches 96.4% by HPLC analysis.
