Abstract

Coronopus didymus is a medicinal plant belonging to family Brassicaceae. Volatile phytochemical constituents from various extracts of Coronopus didymus were investigated by gas chromatography–mass spectrometry to analyze the biologically active constituents of the herb. A total of 69 compounds were identified including 34 from the aerial parts and 35 from roots extract. Despite the parts used, this herb contained mainly volatile esters and sulfur containing compounds. In the n-hexane extract of the aerial parts, ethyl (9Z,12Z,15Z)-octadecatrienoate (22.33 %), ethyl 9Z,12Z-octadecadienoate (9.04 %) and ethyl hexadecanoate (8.80 %) were the major constituents, while in the roots extract benzyl isothiocyanate (20.51 %) and ethyl hexadecanoate (8.44 %) were found to be the major constituents. It was found that aerial parts are quite rich in various biologically active acetates while the roots are quite rich in benzyl isothiocyanate.
