AIM: To investigate the chemical constituents of the roots of Polygala sibirica L. (Polygalaceae) METHOD: The isolation was performed by solvent extraction and various chromatographic techniques, including silica gel, Sephadex LH-20, ODS, semi-preparative HPLC, and preparative TLC. The chemical structures were elucidated based on extensive spectroscopic analysis, including HR-ESI-MS and 1 D- and 2D-NMR spectroscopic data. RESULTS: A total of sixteen compounds, including five xanthones (5, 7-10), five saccharide esters (1, 3, 4, 12, 13), two flavon- oids (14, 16), two triterpenoids (11, 15), one phenylpropanoid (6), and one benzophenone glycoside (2) were isolated. Their struc- tures were determined as sibiricose A7 (1), sibiriphenone A (2), polygalatenoside A (3), polygalatenoside C (4), lancerin (5), 3, 4, 5-trimethoxycinnamic acid (6), 6-hydroxy-1, 2, 3, 7-tetramethoxyxanthone (7), 1, 3, 7-trihydroxy-2-methoxyxanthone (8), onjix- anthone II (9), 1, 2, 3, 6, 7-pentamethoxyxanthone (10), presenegenin (11), 3'-O-3, 4, 5-trimethoxycinnamoyl-6-O-4-methoxy ben- zoyl sucrose (12), tenuifoliside C (13), 5, 3'-dihydroxy-7, 4'-dimethoxyflavonol-3-O-β-D-glucopyranoside (14), tenuifolin (15), and rhamnetin 3-O-β-D-glucopyranoside (16). CONCLUSION: Compounds 1 and 2 are two new compounds from P. sibirica.
