| Abstract
| - Six new sucrose esters, sibiricoses A1−A6 (1−6), two new xanthone C-glycosides, sibiricaxanthones A (7)and B (8), and a new acetophenone glycoside, sibiricaphenone (9), were isolated from the roots of Polygalasibirica together with six known glycosides. The structures of new compounds were elucidated on thebasis of chemical and spectroscopic evidence. The structure of the known xanthone glycoside, polygalaxanthone III (10), was revised.
