Physicochemical characterization of seed oil of jatropha curcas L.collected from Dehradun (Uttarakhand) India.

To study oil contents and fatty acid composition among the samples of Jatropha curcas L. seeds were collected from Dehradun, Uttarakhand. Soxhlet extraction method and gas chromatography (GC) were employed to determine the oil contents of Jatropha seeds and the fatty acid composition of Jatropha oil. The seed oil contents (dry basis) was 46.27% .Physicochemical properties shows acid value (36.46), iodine value (106.00 mg/g) and saponification value (194.70 mg/g.The evaluation of fatty acid composition using gas chromatography (GC) revealed that, oleic (44.93%), linoleic acid (33.40 %), Palmitic acid (15.39%) and Stearic acid (6.26%).
