| Zusammenfassung: | Two new triterpenoids,named as 2 α,3 β,23-trihydroxylurs-12,20（30）-dien-28-oic acid β-D-glucopyranoside（1）,and 2 α,3 β,6 β,20 β,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. |
