Tetranortriterpenoids From Azadirachta indica
Phytochemistry, 1989Abstract 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.

Cardiovascular Effects of Azadirachta indica Extract
Journal of Pharmaceutical Sciences, 1978A crude extract of the leaves of Azadirachta indica was studied for its effects on the cardiovascular system of anesthetized guinea pigs and rabbits. These effects include profound hypotension and a minimal negative chronotropic effect, which increased at higher doses.

A Gram-stain positive actinomycete, strain AZ1-19T, isolated from roots of Azadirachta indica A. Juss. var. siamensis Valeton, collected from Chachoengsao province, Thailand, was characterised taxonomically by using a polyphasic approach. Strain AZ1-19T was found to have characteristics consistent with those of members of the genus Micromonospora.
