Study on Chemical Constituents of Mongolian Medicinal Material Gentiana Veitchiorum
OBJECTIVE To research the chemical components of Mongolian medicinal material Gentiana veitchiorum.METHODS Separation and purification were conducted using silica gel column chromatography,Sephadex LH-20 gel column chromatography,and preparative HPLC,and the compound structure was identified through spectral data and physicochemical constants.RESULTS Ten compounds were obtained from the separation of Gentiana veitchiorum.The compounds were respectively authenticated as 2,3-dihydroxybenzyl alcohol β-glucopyranoside(1),gentiopicroside(2),2'-(O,m-Dihydroxybenzoyl)sweroside(3),isoorientin(4),isoorientin-3'-methyl ether(5),isovitexin(6),isoorientin-4'-O-glucopyranoside(7),isosoapin(8),ursolic acid(9),β-Sitosterol(10).CONCLUSION The compound 1 is authenticated as the new benzyl alcohol glycoside.The compound 10 is firstly separated from this medicinal plant.
