Fatty acid composition and elemental analysis of seed oil of Tectona grandis collected from Dehradun, Uttarakhand, India.
To study oil contents and fatty acid composition of Tactona grandis seeds gas chromatography (GC) and gas chromatography mass spectrum (GCMS) were employed. The seed oil contents (dry basis) was 39.27%. Elemental analysis of seed oil shows that Calcium (1.98%), Magnesium (1.20%), Potassium (0.010%), Nitrogen (0.026%), Chloride (2.83%), Zinc (0.0051%), Nickel (0.0025%), Manganese (0.0042%) and Iron (0.015%). The evaluation of fatty acid composition using gas chromatography (GC) and gas chromatography mass spectrum (GCMS) revealed that, oleic (28.4578%), linoleic acid (56.2071%), Palmitic acid (10.1302%) and Octadecenoic acid methyl ester (5.2049%).
