Abstract
Four novel lupane-type lupane-type triterpenoids (including three norlupane-type triterpenoids), 17β-hydroxy-28-norlup-20(29)-en-3-one (1), 3β,17β-dihydroxy-28,30-bisnorlupan-20-one (2), 3β-hydroxy-20-oxo-30-norlupan-28-al (3) and lup-20(29)-ene-3,23,30-triol (4), were isolated together with ten known lupane triterpenoids (5~14) from the bark of Euonymus alatus forma ciliato-dentatus. Their structures were determined from 1D- and 2D-NMR analysis and comparison of their spectroscopic data with literature values. The known compounds (5~14) were reported for the first time from this plant.
