Abstract:
AIMTo study the chemical constituents of Polygala aureocauda Dunn..
METHODSChemical compounds were isolated by column chromatography and their structures were determined mainly by spectroscopic means (UV, IR, MS, 1HNMR, 13CNMR, HMQC, HMBC).
RESULTSThree 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).
CONCLUSIONCompounds I-III were isolated from Polygala aureocauda Dunn. for the first time, whereas compound I is a new xanthone.
