The chemical constituents of Salacia hainanensis were studied for the first time. Five compounds were isolated from the roots of the plant by silica-gel column chromatography and reverse phase preparative chromatography. Four of them have been identified as friedelin, beta-sitosterol, ursolic acid and mangiferin.
