An investigation of root and stem of Indigofera suffruticosa has led to the isolation of a new nitropropanoylglucopyranoside [2,3,4,6-tetra(3-nitropropanoyl)] α-D-glucopyranose. Its structure was determined by spectroscopic methods as well as GC analysis of the corresponding alditol acetate. Detailed chemical, degradative and spectroscopic studies have led to the isolation and characterization of 2-hydroxyethyl glucosinolate from the seed of Capparis masaikai. This is the first report of this glucosinolate, which is the simplest member of the group of glucosinolates which spontaneously cyclize upon treatment with thioglucoside glucohydrolase (EC 3.2.3.1) [myrosinase], thereby yielding oxazolidine-2-thione.
