In this study, the physicochemical properties and fatty acid composition of Lagerstroemia lanceolata wall (Nana) was investigated. Oil from the seeds of Lagerstroemia lanceolata wall was extracted with light petroleum ether as solvent. The ether extract was evaluated for physico-chemical properties, specific gravity, oil colour, refractive index, saponification value, unsaponifiable matter, acid value and iodine value. The fatty acid profile analysis of the oil was also carried out by Gas Liquid Chromatography (GLC), using two fatty acid methylating reagents, (trimethyl sulfonium hydroxide TMSH and sodium methylate). The stability of the oil was determined by induction period (IP) using (Rancimat test). The oil has five main fatty acids:Palmitic acid, Steric acid, Palmitolic acid, Oleic acid and Linoleic acid. Oleic acid (42.20%) is the primary component followed by Linoleic acid (24.80%), Palmitic acid (15.20%) and Stearic acid (6.10%). Oleic and linoleic acid are the principal component acids with (about 65% of the total fatty acids). Palmitolic acid was as the minor constituent which amounted only 3.80%.

Oil from the seeds of Lagerstroemia lanceolata wall was extracted with light petroleum ether as solvent. The ether extract was evaluated for physico-chemical properties, specific gravity, oil colour, refractive index, saponification value, unsaponifiable matter, acid value and iodine value. The fatty acid profile analysis of the oil was also carried out by Gas Liquid Chromatography (GLC), using two fatty acid methylating reagents, (trimethyl sulfonium hydroxide TMSH and sodium methylate). The stability of the oil was determined by induction period (IP) using (Rancimat test). The oil has five main fatty acids:Palmitic acid, Steric acid, Palmitolic acid, Oleic acid and Linoleic acid. Oleic acid (42.20%) is the primary component followed by Linoleic acid (24.80%), Palmitic acid (15.20%) and Stearic acid (6.10%).
