Abstract

The hydro-distilled volatile components were obtained from the herb (leaf and stem) of Cajanus lineatus (Wight & Arn.) Maesen (Syn: Atylosia lineata Wight & Arn.) of the family Fabaceae, commonly known as Janglitur in India, and the essential oil was analysed for the first time using GC-FID and GC-MS. Sixty-two compounds were identified from the herb oil of C. lineatus. The major compounds were identified as β-caryophyllene (10.6%) and α-humulene (10.3%). The oil was found to be rich in sesquiterpene hydrocarbons (51.5%) type compounds.

Keywords: Cajanus lineatus (Wight & Arn.) Maesen; GC-MS; volatile oil constituents; α-humulene; β-caryophyllene.
