Abstract:
Objective: To study the chemical constituents from the whole plant of Swertia davidi. Methods: The chemical constituents were isolated and purified with silica gel column chromatography, silica gel chromatography, etc. The structures of the compounds were identified by physicochemical properties and various spectroscopic methods. Results: Sixteen compounds were isolated as uvaol (1), oleanolic acid (2), 5-carboxyl-3, 4-dihydrogen-1H - 2-benzopyran-1-one (3), 3β, 12β-pregnane-16-12-ene-20 (4), swertisin (5), 6-C-β-glucopyranosyl-7-O-methylluteolinidin (6), isoscoparin (7), 6-demethoxy-7-methylcapillarisin (8), 3-acetoxy-28-hydro-xyl-12-eneurs (9), gentiopicroside (10), N-pentacosy-2-carboxy-benzoylamide (11), 4-O-glycosyloxy-2-hydroxy-6-methoxy-acetophenone (12), quercetin-3-O-β-D-xylopyranosyl-(1→2) - β-D-galactopyranoside (13), 8-epikingiside (14), 3, 5-dicaffeoylquinicacid (15), and 2-methylphenyl-1-O-β-D-glucopyranoside (16). Conclusion: All the compounds are isolated from S. davidi for the first time.
