Abstract

Two new triterpenoids, guajavolide (2α,3β,6β,23-tetrahydroxyurs-12-en-28,20β-olide; 1) and guavenoic acid (2α,3β,6β,23-tetrahydroxyurs-12,20(30)-dien-28-oic acid; 2) along with one known triterpene oleanolic acid (3) were isolated from the fresh leaves of Psidium guajava. Their structure elucidation and stereochemistry were determined by spectroscopic experiments, including 2D-NMR techniques.
