[Studies on the chemical constituents in root bark of Polygala tenuifolia (II)].
OBJECTIVE
To study the chemical constituents of Polygala tenuifolia.


METHODS
Isolations were performed on various chromatography columns and structure elucidations were aided by spectral data and chemical property analyses.


RESULTS
Four compounds were isolated from the roots of P. tenuifolia. Their structures were identified as sibiricose A5 (1), sibiricose A6 (2), tenuifoliside A (3) and 3',6-disinapoyl sucrose (4).


CONCLUSIONS
Compounds 1 and 2 were isolated from this plant for the first time.
