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 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 (S-8), have also been identified through GC-MS.
