摘要: Preparative high-speed counter-current chromatography (HSCCC) was successfully applied for separation and purification of sesquiterpenoids from an extract of Tussilago farfara L. with a two-phase solvent system composed of n-hexane-ethyl acetate-methanol-water (1:0.5:1.1:0.3, v/v/v/v). The separation produced a total of 32 mg of tussilagone. 18 mg of 14-acetoxy-7β-(3'- ethyl cia-crotonoyloxy)-lα-(2-methyl butyryloxy)-notonipetranone and 21 mg of 7β-(3'-ethyl cis-crotonoyloxy)-lα-(2- methyl butyryloxy)-3,14-dehydro-Z-notonipetranone from 500 mg of the crude extract in one step separation with the purity of 99.5, 99.4 and 99. 1%, respectively, as determined by HPLC. The structures of these compounds were identified by ESI-MS, ~1H-NMR and ~(13)C-NMR.
