A new xanthone-O-glycoside, polycaudoside A, together with 2'-benzoylmangiferin, 1-methoxy-7-hydroxyxanthone, 1,2,8-trihydroxyxanthone, euxanthone, gentisein, wubangziside A, wubangziside B, 1,3-dihydroxy-2-methoxyxanthone, lancerin and neolancerin, stigmasterol, stigmastrol-3-O-D-glucoside, p-hydroxybenzoic acid, dihydroquercetin and quercetin were isolated from the roots of Polygala caudata. Their structures were established on the basis of chemical studies and spectral evidence, including 2D NMR analyses.
