The composition of the essential oil of the fresh whole Acmella radicans (Jacq.) R.K. Jansen var. radicans (Asteraceae) plant and two root-extracts from southern India were investigated by gas chromatographic–spectroscopic (GC-FID and GC-MS) and olfactive methods to identify those volatiles responsible for the characteristic, pleasant aroma of these samples. The essential oil was found to be rich in 2-tridecanone (30.1%), 1-pentadecene (25.2%), trans-β-caryophyllene (12.8%), elemol (4.6%), guaiol (3.1%) and some further caryophyllene derivatives; the petroleum ether extract was rich in 1-pentadecene (54.1%), 2-tridecanone (10.3%), 2-pentadecanone (6.7%), 2-pentadecanol (4.1%), trans-β-caryophyllene (3.6%) and 1-tridecene (3.0%); and the petroleum ether–methanol–ethyl acetate extract was rich in 2-tridecanone (58.2%), 1-pentadecene (15.00%) and palmitic acid (16.6%). A correlation of the identified constituents of the three samples with their single odour impressions is also given.
