Abstract
Objective To investigate the chemical composition of the flowers of Eriobotrya japonica. Methods Four constituents were isolated from the ethanolic extracts of flowers of Eriobotrya japonica (Thunb) Lindl and were identified by chemical methods and spectroscopic (IR, MS,1HNMR,13CNMR). Results The structures were identified as: Oleanolic acid (Ⅰ),Ursolic acid (Ⅱ) , 2α,3α,19α-Trihydroxyurs-5,12-dien-28- acid (Ⅲ) and 2β, 3β, 23α-Trihydroxyolean-12-en-28-acid (Ⅳ).
