Abstract

Jatropha curcas oil was extracted using n-hexane as solvent in the Soxhlet extraction method. The physicochemical properties of Malaysian Jatropha curcas oil were evaluated. The result showed that the Jatropha seeds consist of 60% (dry w/w) crude oil. The physicochemical properties showed that the seed oil contained low moisture level of 0.02 ± 0.01 %, acid value (1.50 ± 0.07%), iodine value (91.70 ± 1.44 mg/g), peroxide value (0.66 ± 0.04 miliequivalence/kg) and saponification value of 208.5 ± 0.47 mg/g respectively. Gas chromatography analysis showed that oleic acid (46.00 ± 0.19%) appears as dominant fatty acid in seed oil followed by linoleic acid (31.96 ± 0.19%) and palmitic acid (13.89 ± 0.06%). High performance liquid chromatography (HPLC) results showed that the dominant triacylglycerols present were PLL (20.40%), OOL (17.98%), POO (15.02%), OOO (14.89%) and OLL (14.00%).
