Their structures were fully elucidated on the basis of MS, 1D and 2D-NMR data. The structures of xanthones were identified as 1, 7-dihydroxy-3-methoxyxanthone-7-O-β-D-glucopyranoside (1), swertiapuniside (2), 1, 3, 8- trihydroxy -4, 5-dimethoxyxanthone-1-O-β-D-glucopyranosyl(6→1)-O-β-D-glucopyranoside (3), 1, 2, 8-trihydroxy-5, 6-dimethoxyxanthone-2-O-β-D-glucopyranoside (4), 1, 3, 7, 8-tetrahydroxyxanthone-1-O-β-D-glucopyranoside (5), 1, 3, 5, 8-tetrahydroxy-5, 6, 7, 8-tetrahydroxanthone (6), 1, 3, 5-thihydroxyxanthone (7),1, 3, 5, 8-tetrahydroxyxanthone (8), 1, 2, 8-trihydroxy-5, 6-dimethoxyxanthone (9), bellidifolin (10), mangiferin (11), swertianolin (12).
