| Abstract: | Five new xanthenone O‐glycosides, sibiricaxanthone C ( 1 ), sibiricaxanthone D ( 2 ), sibiricaxanthone E ( 3 ), sibiricaxanthone F ( 4 ), and sibiricaxanthone G ( 5 ) were isolated from the roots of Polygala sibirica L., together with the six known xanthenone glycosides 6 – 11 . The structures of new compounds were elucidated on the basis of spectral data and acid hydrolysis. |
