Abstract
The oil from stems, leaves and roots of Elephantopus scaber Linn. were extracted by solvent maceration technique. The percentage yield oil from stems, leaves and roots are 0.001%, 0.003% and 0.04%, respectively. The stem oil gives major constituents of pentacosane (12.3%), lupenyl acetate (11.7%) and fern-7-en-3β-ol (11.0%), while the leaf oil contains isooctyl phthalate (19.2%), hexadecanoic acid (15.0%) and α-linolenic acid (5.0%) as the major components. The major constituents identified in the root oil are hemellitol (11.6%), octyl phthalate (6.0%), 1-nonadecanol (5.6%) and 1-octadecanol (5.5%). There were only three compounds detected and identified in all three parts of the plant, namely decanedioic acid, bis-(2-ethylhexyl)ester, dotriacontane and pentacosane. The oils were analysed by gas chromatography-mass spectrometer and the compounds were identified by comparison with the mass spectral fragmentation pattern database.
