RESUMO
Five new ursane-type triterpenoids 1-5, and one new oleanane-type triterpenoids 7 were isolated from the MeOH extract of the aerial parts of Maytenus diversifolia. Their structures were elucidated by analyzing spectroscopic data and chemical transformation. Compounds 3 and 5 exhibited significant lethal activity in the brine shrimp lethality test (BST).
