This investigation reports the detection and determination of the chemical components from polar extract of the seeds and leaves of Indian Mustard i.e. Brassica juncea L genotypes using gas chromatography-mass spectrometry (GC-MS). Many of the components in Brassica juncea L seeds and leaves are essential for proper human nutrition as primary and secondary metabolites. The main phytochemicals identified in seeds were 2-butyl isothiocyanate (32.46%), phenylethyl isothiocyanate (28.01%), alpha-D-galactopyranoside (25.19%), linolenic acid (16.05%), tetradecanoic acid (11.32%) and oleic acid (1530%). The GC-MS results clearly show that the major compounds identified in the leaves were alpha-methyl-D-mannopyranoside (27.18%), 2-butyl isothiocyanate (24.24%), beta-D-glucopyranoside (24.54%), furaldehyde (15.96%), 1-phenyl ethanol (23.33%), ethyl benzoate (14.50%), linolenic acid (13.99%) and oleic acid (12.75%). The study confirmed that the glucosinolates with allyl and phenylethyl groups as side chain are predominant compounds in Brassica juncea L Due to variable patterns of bioactive compounds Brassica extract could be used as natural antioxidant and source for various medicinal purposes.
