[Studies on chemical constituents in roots of Polygala tenuifolia].
OBJECTIVE
To study the chemical constituents from the roots of Polygala tenuifolia.


METHODS
Column chromatographic techniques were employed for isolation and purification of chemical constituents of the plant and the structures were elucidated by spectroscopic analysis.


RESULTS
Five chemical constituents were isolated and elucidated as 4-C-beta-glucopyranosyl-1,3,6-trihydroxy-7-methoxyxanthone (1), 4-C-[beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranosyl]-1,3,6- trihydroxy-7-methoxyxanthone (2), presenegenin (3), presenegenin-3-O-beta-D-glycopyranoside (4) and daucosterol (5), respectively.


CONCLUSIONS
Compounds 1,3,4 and 5 were isolated from this plant for the first time. Compound 1 is a new natural product.
