To study the chemical constituents from the roots of Polygala tenuifolia.Column chromatographic techniques were employed for isolation and purification of chemical constituents of the plant and the structures were elucidated by spectroscopic analysis.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.Compounds 1,3,4 and 5 were isolated from this plant for the first time. Compound 1 is a new natural product.
