Seven xanthones and two flavonoids were isolated from the roots of Polygala caudata and identified using thin-layer chromatography, melting points and spectroscopic methods as euxanthone (1,7-dihydroxyxanthone), gentisein (1,3,7-trihydroxyxanthone), wubangziside A (euxanthone-7-O-β-D-apiofuranosyl-(1–6)-β-D-glucopyranoside), wubangziside B (euxanthone-7-O-β-D-glucopyranside), 1,3-dihydroxy-2-methoxyxanthone, lancerin (1,3,7-trihydroxyxanthone-4-C-β-D-glucopyranoside) and neolancerin (1,3,7-trihydroxyxanthone-2-C-β-D-glycopyranoside), and dihydroquercetin and quercetin.
