Abstract

Malaysian rubber seed oil was extracted using hexane as solvent in the soxhlet extraction method. The physicochemical properties of the oil, i.e. acid value, free fatty acid percentage, iodine value, saponification value, unsaponifiable matter and color were evaluated. The fatty acid composition of the lipid was investigated using gas chromatography. Oleic acid (22.95±0.15) and linoleic acid (37.28±0.10) were detected as the dominant fatty acids while palmitic acid and stearic acid were the saturated fatty acids found in the oil. It appears to have linolenic acid (19.22±0.21) as one of the five major fatty acids in the lipid fraction. Monounsaturated triacylglycerol, PPL and polyunsaturated triacylglycerols of LnLnL and LnOO were the major triacylglycerols found. FTIR showed the characteristic strong absorption bands at 1746 cm-1 of a C=O functional group and at 1641 cm-1 for a double bond respectively. The 1H NMR and 13C NMR spectra indicated that the triacylglycerols were saturated and unsaturated fatty acids, such as terminal methyl, methylene, carbonyl, glyceryl, esters, and olefinic carbon. Thermal properties of the oil determined by their differential scanning calorimetry melting and crystallization curves were represented by simple thermograms. The solid fat content of the oil contained low percentages of solids (0.24%, 0.13%, 0.12%, 0% and 0%) at 0°, 5°, 10°, 15° and 20 °C respectively.
