Abstract
Various extraction characteristics of oil from Hevea brasiliensis seed has been studied with different solvents like hexane, petroleum ether and tetrahydrofuran. Parameters affecting the extraction process were evaluated for temperature, extraction time and particle size. These parameters significantly influence the oil extraction process to obtain maximum yield. From the results, it was observed that maximum yield of 49.94wt% oil was obtained with hexane for the optimized condition 0.35 mm particle size, 60°C extraction temperature and 180 min extraction time. Oil yield increases with increase in temperature and time, but decreases with increase in particle size. Physicochemical properties of rubber seed oil were investigated using standard techniques.
