Abstract

Three acidic triterpense were isolated from the ethyl acetate soluble fraction of the fruits of Chenomeles sinensis (Rosaceae) together with previously reported oleanolic acid and ursolic acid by repeated silica gel colunm chromatography. Their structures have been elucidated as $2{\alpha},{\;}3{\betha}-dihydroxyolean-l2-en-28-oic$ acid(l. maslinic acid), $2{\alpha},{\;}3{\alpha},{\;}19{\alpha}-trihydroxy-urs-12-en-28-oic$ acid (2, euscaphic acid), and $2{\alpha},{\;}3{\betha}-dihydroxyolean-l2-en-28-oic$ acid (3,tormentic acid), respectively, on the basis of chemical and spectral evidence.
