Abstract

Aim: To study the chemical constituents of Polygala aureocauda Dunn..

Methods: Chemical compounds were isolated by column chromatography and their structures were determined mainly by spectroscopic means (UV, IR, MS, 1HNMR, 13CNMR, HMQC, HMBC).

Results: Three compounds were isolated and identified as 3-hydroxy-1,4-dimethoxyxanthone (I), 1, 7-dihydroxy-2, 3-methylendioxyxanthone (II), 7-hydroxy-1-methoxy-2, 3-methylendioxyxanthone (III).

Conclusion: Compounds I-III were isolated from Polygala aureocauda Dunn. for the first time, whereas compound I is a new xanthone.
