Abstract
Five new tetranortriterpenoids-walsurin (1), isowalsuranolide (2), walsuran
olide (3), 11 beta-acetoxywalsuranolide (4), and 20,22-dihydro-22,23-epoxyw
alsuranolide (5)-and three new natural tetranortriterpenoids-11 beta-hydrox
ydihydrocedrelone (6), 11 beta-acetoxydihydrocedrelone (7), and 11 beta-hyd
roxycedrelone (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.
