Abstract: Three xanthone glycosides, a flavonoid glucoside and a triterpen acid have been isolated from Swertia franchetiana H. Smith (Gentianaceae). One of them is a new xanthone glyco- side and its stucture is established as 1-O-[β-D-xylopyranosyl-(1-6)-β-D-glucopyranosyl] 3, 5-dimethoxyxanthone (Ⅺ), Others are identified as swertianolin, swertisin, mangiferin and oleanolic acid by chemical and spectral means, respectively.

Key words: Gentianaceae, Swertia, Xanthone glycoside, Flavonoid glucoside, Triterpen
