Abstract: Objective: To investigate the chemical constituent from the roots of Gentiana straminea.; Methods: The constituents were separated by microporous resin,silica gel,Sephadex LH-20 and preparative column chromatography and their structures were elucidated by NMR and MS spectral methods.; Results: Twelve chemical constituents were isolated from the roots of Gentiana straminea and their structures were identified as daucosterol( 1),β-sitosterol( 2),ursolic acid( 3),sweroside( 4),swertiamarin( 5),gentiopicroside( 6),6’-O-acetyl-gentiopicroside( 7),6’-O-β-D-glucopyranosyl-sweroside( 8),protocatech uic aldehyde( 9),protocatechuic acid( 10),methyl gallate( 11) and dibutyl phthalate( 12).; Conclusion: The compounds 8,9,10,11 and 12 are obtained from this plant for the first time.;
