Tetranortriterpenoids From Azadirachta indica

Phytochemistry, 1989
Abstract Two new tetranortriterpenoids, an aldehyde named nimbanal and the 3-acetyl derivative of salannol, were isolated from the seed extract of neem, Azadirachta indica . The structure of nimbanal was established by spectral data while that of salannol-3-acetate was proved by its correlation with salannin.
