title: Physico-chemical properties of Tecoma stans Linn. seed oil: a new crop for vegetable oil.
abstract: Tecoma stans Linn. is known to have various medicinal and therapeutic properties. However, to our knowledge, no information is available regarding their seed oils. In this study, the fatty acid (FA) compositions, physico-chemical properties and antioxidant capacities of T. stans seed oils (TSOs) were investigated. The oil content of the seeds was 15%. The FAs of the TSOs were analysed by GC-MS. α-Linolenic (45.47%), oleic (23.56%), linoleic (11.48%), palmitic (6.09%) and stearic (4.12%) acids were the major detected FAs. γ-Linolenic acid and stearidonic acid, unusually FAs, were also present (1.04% and 6.65%, respectively). The total tocol content in the TSOs was found to be 266.06 mg/100 g. The main component was γ-tocopherol (78.93%). The total phenolic content (168.69 mg GAE/100 g oil) and total flavonoid content (5.54 mg CE/g oil) were also determined in the TSOs.
