Two new triterpenoids,named as 2α,3β,23-trlhydroxylurs-12,20(30)-dien-28-oic acid β-D-glucopyranoside (1),and 2α,3β,6β,20β3,23,30-hexahydroxyurs-12-en-28-oic acid (2),together with four known triterpenoids were isolated from the leaves of Psidium guajava L.Their structures were elucidated on the basis of mass and spectral evidence.
