Abstract
In the current study, we reported the concentration of heavy metals (ppm), physicochemical properties and fatty acid composition of Sesamum indicum seed oil from arid zone in Rajasthan. MP-AES is used for the analysis of heavy metals from the seed oil of Sesamum indicum. The heavy metals are found in seed oil in following order: Zn (7.92), Fe (1.14), Mn (0.74), Pb (0.07), Ni (0.05) and Cr (0.01) in ppm respectively. Sesamum indicum oil was tested for its physicochemical properties. The proximate analysis revealed 46.00% oil content. HPLC was used to determine the fatty acid composition of the oil sample. Saturated, monounsaturated and polyunsaturated fatty acids were recorded for 15.52%, 42.86% and 41.32% of the total amount of fatty acids respectively. Linoleic acid (42.38%) was the most abundant fatty acid followed by oleic acid (41.20%) and palmitic acid (9.90%). Stearic acid (5.62%), linolenic acid (0.48%) and palmitoleic acid (0.12%) were present in small amounts.
