[Studies on the chemical constituents of Vaccinium iteophyllum].

7 compounds were isolated from the ethyl-acetate extract of Vaccinium iteophyllum Hance by using repeated silical gel column chromatography. These 7 compounds were identified by means of physico-chemical propertic and spectroscopic analysis as beta-sitosterol (I), ursolic acid (II), taraxerol (III), taraxerone (IV), friedelin (V), friedelinol (VI), 19,24-dihydroxyurs-12-en-3-one-28-oic acid (VII). The chemical constituents from this plant were reported here for the first time.
