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.
