Abstract

Five new tetranortriterpenoids-walsurin (1), isowalsuranolide (2), walsuranolide (3), 11beta-acetoxywalsuranolide (4), and 20, 22-dihydro-22,23-epoxywalsuranolide (5)-and three new natural tetranortriterpenoids-11beta-hydroxydihydrocedrelone (6), 11beta-acetoxydihydrocedrelone (7), and 11beta-hydroxycedrelone (8)-together with a known tetranortriterpenoid, cedrelone (9), were isolated from the bark of Walsura yunnanensis. The structures of 1-8 were determined on the basis of spectral evidence.
