Chemical Constituents of the Polar Part of Swertia Punicea Hemsl

Objective: To investigate the chemical constituents of Swertia punicea Hemsl. Methods: The compounds were isolated and purified by silica gel, ODS, MCI and Sephadex LH-20 column chromatography, and their structures were elucidated by TLC, UV,1H-NMR, and 13C-NMR analysis. Results: Six compounds were isolated and identified from butanol fraction of Swertia punicea extract, and they are 1,5,8-trihydroxy-3-methoxyxanthone （I）, 1,3,8-trihydroxy-5-methoxyxanthone （II）, 1,8-dihydroxy-3,5-dimethoxyxanthone（III）, 1,3,5,8 tetrahydroxyxanthone（IV）, oleanolicacid（V）and sweroside（VI）. Conclusion: Compound（II） was obtained from this plant for the first time.
