Abstract:
A new xanthone glycoside, swertiapuniside (V), has been isolated from the whole plant of Swertia punicea Hemsl. The structure was elucidated as 1,5,8-trihydroxy-3-methoxyxanthone-8-O-beta-D-glucopyranosyl (1-6)-O-beta-D-glucopyranoside by means of chemical and spectroscopic data. Four other known xanthones mangiferin (I), bellidifodin (II), 1,3,5,8-tetrahydroxyxanthone (III) and swertinolin (IV) were also identified.
