AbstractObjective: To separate and prepare gentiopicroside and sweroside from the extracts of Swertia franchetiana H.Smith by high speed counter-current chromatography (HSCCC). Method: Chloroform: menthanol: water = 4:4:2 (v/v/v) as solvent system, the upper one was stationary phase while the lower one was mobile phase; ultrasonic degassed for 20min; the rotating velocity of 850 r/min; mobile phase flow rate of 2ml/min; the detective wavelength of 254 nm; the purity of product was identified by polarimeter. Result: 14 mg gentiopricroside and 27 mg swersoside were obtained from 100 mg crude extracts of Swertia franchetiana H.mith, the specific rotation [a]tD of which were -196.3°and -126.6°respectively, which suggested the products were of high purity. Conclusion: The study would lay a feasible way for the large scale preparation of gentiopicroside and sweroside by HSCCC.
