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.
黄钟花已知具有多种药用和治疗特性。然而，据我们所知，关于其种子油尚无相关信息。在本研究中，对黄钟花种子油（TSOs）的脂肪酸（FA）组成、理化性质和抗氧化能力进行了研究。种子的含油量为15%。通过气相色谱 - 质谱联用仪（GC-MS）分析了TSOs的脂肪酸。检测到的主要脂肪酸为α-亚麻酸（45.47%）、油酸（23.56%）、亚油酸（11.48%）、棕榈酸（6.09%）和硬脂酸（4.12%）。还存在γ-亚麻酸和硬脂酸，这两种脂肪酸不常见（分别为1.04%和6.65%）。发现TSOs中的生育酚总含量为266.06毫克/100克。主要成分是γ-生育酚（78.93%）。还测定了TSOs中的总酚含量（168.69毫克没食子酸当量/100克油）和总黄酮含量（5.54毫克儿茶素当量/克油）。
