Nortriterpenoids from Chukrasia tabularis var. velutina.
Five new limonoids, tabularisins E-I ( 1- 5), and a new dinorcycloartane, (24 R)-28,29-dinor-cycloartane-3beta,24,25-triol ( 6), together with three known compounds, were isolated from the twigs and leaves of Chukrasia tabularis var. velutina. Their structures were elucidated primarily on the basis of spectroscopic methods.
