Studies on the EtOH extract of fresh pods of
Moringa
oleifera have resulted in the isolation
of
a novel glycoside niazidin (1) possessing an
O-nitrile thiocarbamate group, along with
thiocarbamate, carbamate, and isothiocyanate glycosides. Their
structures have been determined
through spectral studies, including appropriate 2D NMR experiments and
chemical reaction.
Fatty acid esters, long-chain hydrocarbons, carbamic acid,
isocyanates, isothiocyanates, phenolic
esters, nitriles, nitrile ester (3), polysulfide sulfinate
(4), and a benzyl thiocarbamate (5),
along
with elemental sulfur (S8), have also been identified
through GC−MS.
