The essential oil from the stems of Chasmanthera dependens was obtained by hydro-distillation and collected into hexane. Analysis of the oil was carried out on a combined gas chromatograph.mass spectrometer equipped with an HP-5 MS (5% phenylmethsiloxane) capillary column at a temperature programme of 1200C (5 min) increased at 50C /min to 320oC and held for 5 min. Two components n-hexadecanoic acid and oleic acid eluted at retention times 21.413 and 24.308 min respectively amounted to a total concentration of 56.92%. Some other minor components, namely, tetradecanoic acid, 1, 2 benzenedicarboxylic acid butyl-8-methylnonylester, heptadecanoic acid and estra-1, 3, 5(10)-trien-17á-ol, a steroid, were identified.
