Separation and Purification of Calycosin-7-glucoside and Ononin from Astragalus Membranceus by High-speed Counter-current Chromatography
摘要
Abstract
Objective:To establish the method of separating and purifying the calycosin-7-glucoside and ononin from astragalus membranceus by high-speed counter-current chromatography. Methods:The crude extract of astragalus membranceus was separated and purified by HSCCC with a two-phase solvent system com-posed of n-hexane-ethyl acetate-methanol-water ( 1:10:2:10 ) and ethyl acetate-ethanol-n-butyl alcohol-water (30:10:6:50) respectively. The lower phases were used as mobile phases with two flow rates of 2.5 mL·min-1 and 2.0 mL·min-1,while the apparatus rotated at 900 r·min-1 and the wavelength were detected at 254 nm. The structures of the target compounds were identified by HPLC. Results:From 300 mg crude extract of as tragalus membranceus,two compounds with calycosin-7-glucoside (20 mg) and ononin (25 mg) were obtained. The purities of these two compounds determined by HPLC were both over 95%. Conclusion:High-speed counter-current chromatography is an efficient method for separating and purifying the calycosin-7-glucoside and ononin from astragalus membranceus.关键词
