摘要：

A novel bisxanthone C-glycoside, 3-O-demethylswertipunicoside, structurally related to swertipunicoside, was isolated from whole plants of Swertia punicea. Determination of its structure was based on the interpretation of the spectroscopic data, particularly selective INEPT NMR spectra, and characterized as 1,3,5,8-tetrahydroxy-7-(1',3',6',7'-tetrahydroxy-9'-oxo-4'-xanthyl) xanthone 2'-C-beta-D-glucopyranoside.
