摘要：

Three new tetranortriterpenoids, 6-deacetylnimbinal (1), nimbinol (3), and 28-deoxonimbolide (6), related to nimbin and nimbolide, have been isolated from Azadirachta indica. (1) and (6) were found in the leaf extracts, (3) in the seeds. The assignment of the structures (1), (3), and (6) was achieved on the basis of 1H and 13C n.m.r. analyses and chemical transformations. The n.m.r. spectra of nimbanal (2), 6-deacetylnimbin (4), nimbin (5), and nimbolide (7) were partially reassigned in this connection. © 1990.
