RESULTSFive compounds were isolated and identified as: beta-sitosterol (I), sucrose (II), n-octacosanol (III), 2-methyl-5-(2'-hydroxypropyl)-7-hydroxy-chromone-2'-O-beta-D-glucopyranoside (IV) and piceatannol (V).

CONCLUSIONCompound IV is a new compound. Compounds II, III and V were obtained from this plant for the first time.
