ISOLATION AND STRUCTURE ELUCIDATION OF A NOVEL GLYCOSIDE NIAZIDIN FROM THE PODS OF MORINGA-OLEIFERA

Studies on the EtOH extract of fresh pods of Moringa oleifera have res ulted in the isolation of a novel glycoside niazidin (1) possessing an O-nitrile thiocarbamate group, along with thiocarbamate, carbamate, a nd isothiocyanate glycosides. Their structures have been determined th rough spectral studies, including appropriate 2D NMR experiments and c hemical reaction. Fatty acid esters, long-chain hydrocarbons, carbamic acid, isocyanates, isothiocyanates, phenolic esters, nitriles, nitril e ester (3), polysulfide sulfinate (4), and a benzyl thiocarbamate (5) , along with elemental sulfur (S-8), have also been identified through GC-MS.
