Study of Heavy Metals from Seed Oil of Nicotiana Tabacum Plants of Solanaceae Family from Arid Zone
Abstract: An important source of oils with pharmacological, industrial, and nutritional benefits is plant seeds. An oil is appropriate for a certain use depends on its properties and fatty acid composition. Nicotine is an alkaloid found in tobacco leaves (Nicotiana tabacum). The chemical that causes smoking to become such an addictive habit is nicotine, which is both well-known and notorious. Nicotiana tabacum belongs to the family Solanaceae. The oil content, Protein content and moisture (by solvent extraction method in petroleum ether) of Nicotiana tabacum were found 37.5%, 35.5%, and 5.6%, respectively. The Soxhlet equipment was used to extract the oil, and AAS (Atomic Absorption Spectroscopy) revealed the presence of heavy metals such as Fe, Zn, Cu, Cd, Cr, Ni, Co, and Pb in Nicotiana tabacum seed oil. In Nicotiana tabacum seed, the Fatty acids were found, specially, Myristic acid (C14:0), Palmitic acid (C16:0), Stearic acid (C18:0), Oleic acid, Linoleic acid (C18:2) and Linolenic acid (C18:3) as 9.60%, 8.5%, 2.5%,13.5%, 72.03%, and 27.97%, respectively. Iodine value (136.8 g I2/100g), Saponification value (186.6 mg/g KOH), un-saponification value (1.42% w/w), and Peroxide value (meq. /kg) (1.92) are the physicochemical characteristics of Nicotiana tabacum. The Physico-chemical characteristics of the seed oil of Nicotiana tabacum were determined using AOCS methods.
