The Volatile oil of Abutilon hirtum (Lam.) Sweet leaves extracted by a Clevenger approach and the fatty acid content of this species as a result of petroleum ether extraction were investigated using gas chromatography-mass spectrometry (GC-MS) technique. GC-MS analysis of the volatile oil revealed the presence of 63 compounds, with (2E,6E)-farnesol (6.56%), E-caryophyllene (4.68%), caryophyllene oxide (4.37%) and βcopaen-4-α-ol (3.51%) as the major components. On the other hand, 8 fatty acids of which three were identified as linolenic acid methyl ester, which was the major identified fatty acid methyl ester (38.74%), followed by palmitic acid methyl ester (29.09%) and linoleic acid methyl ester (18.14%). The identification of the compounds depends on the retention time and mass spectrum.
