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). Conclusion　The compounds Ⅰ, Ⅱ, Ⅲ and Ⅳ were obtained from the flowers of Eriobotrya japonica for the first time.
