Volatile oils were extracted from the leaves of Jatropha multifida using solvent free microwave and hydrodistillation methods and the oils obtained were analyzed by gas chromatography-mass spectrometry (GC-MS). The major compound as observed is eucalyptol with 70.38 and 35.62 % for solvent-free microwave extraction (SME) and hydrodistillation extraction (HDE), respectively. The oil compositions were dominated by oxygenated compounds. Oxygenated monoterpenes were prevalent in contrast to monoterpenes hydrocarbons. The oils were also characterized by oxygenated sesquiterpenes (SME, 6.05 %; HDE, 7.34 %). This study may provide information on a suitable method of extraction of the essential oil for industrial application and may assist in the realization of the essential oil as a natural source of plant and animal food additives. These various bioactive compounds in the essential oil may partially justify their use in folklore medicine.
