摘要：
Three pentacyclic triterpenoids including one new guajavanoic acid (2) and two known obtusinin (1) and goreishic acid I (3) have been isolated from the leaves of Psidium guajava. The new constituent 2 has been characterized as 2alpha-hydroxy-3beta-p-E-coumaroyloxyurs-12, 18-dien-28-oic acid through H-1-NMR and, C-13-NMR (broad band and DEPT). This is the first report of isolation of compound 1 and 3 from the genus Psidium.
