Abstract

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 2α-hydroxy-3β-p-E-coumaroyloxyurs-12, 18-dien-28-oic acid through ¹H-NMR and ¹³C-NMR (broad band and DEPT). This is the first report of isolation of compound 1 and 3 from the genus Psidium.
