Abstract: | Physicochemical characteristics and fatty acid composition of Lasiococca comberi Haines (Euphorbiaceae), an endangered forest tree species, were determined for the first time. The oil, protein, crude fibre and carbohydrate contents in seeds were 41.5, 13.8, 22.2 and 11.6%, respectively. The refractive index, pH, specific gravity, saponification value, iodine value, peroxide value and p-anisidine value of seed oil were 1.4781, 6.4, 0.9, 178.4 mg KOH/g, 196 g I2/100 g of oil, 5.1 mEq O2/kg and 188.4, respectively. The predominant fatty acids were linolenic acid (65.3%), oleic acid (13.8%), linoleic acid (7.1%) and palmitic acid (5.3%). HPLC analysis revealed the presence of α-tocopherol (13.2 mg/100 g) and γ-tocopherol (6.3 mg/100 g) as the major tocopherols. The results indicated that L. comberi seed oil can be classified as drying oil having possible applications in different industries and as an important dietary source of omega-3 fatty acids. |
