Abstract

The genus Ocotea of the Lauraceae family has species whose wood is employed in construction and for other purposes including as biofuel, for disinfection, cosmetics, and in the treatment of various diseases. Studies regarding Ocotea caudata’s phytochemical and pharmacognostic uses are scarce, thus, this work is the first to study its fruits. O. caudata (Nees) Mez fruits from Colombia were investigated for their oil content. Heptane extraction from O. caudata fruit oil yielded 54.9 % of total lipids, where the fatty acid composition was determined. The oil analysis by gas chromatography with flame ionization detection (GC-FID) demonstrated that lauric acid was the most abundant fatty acid (51.7 %, C12:0). In addition to lauric acid, oleic acid (23.6 %, C18:1) and palmitic acid (16.6 %, C16:0) were found. The fatty acid composition was confirmed by gas chromatography-mass spectrometry (GC-MS). O. caudata can be considered as a species that accumulates medium-chain saturated fatty acids (C12) and long-chain unsaturated fatty acids (C18). In conclusion, many of its health benefits may be due to its high content of lauric acid. Therefore, this oil is highly regarded for its nutritional and health properties.

哥伦比亚樟科果实中脂肪酸组成

樟科的ococtea属有一些树种，其木材用于建筑和其他用途，包括生物燃料、消毒、化妆品和治疗各种疾病。关于尾茶的植物化学和生药学用途的研究很少，因此，本工作是第一次对尾茶果实进行研究。研究了产自哥伦比亚的O. caudata (Nees) Mez果实的含油量。从尾果油中提取的庚烷含量占总脂质含量的54.9%，并测定了其脂肪酸组成。气相色谱-火焰离子化检测(GC-FID)分析表明，月桂酸含量最高(51.7%，C12:0)。除月桂酸外，还发现了油酸(23.6%，C18:1)和棕榈酸(16.6%，C16:0)。脂肪酸组成经气相色谱-质谱联用(GC-MS)确证。尾鱼可以认为是一种积累中链饱和脂肪酸(C12)和长链不饱和脂肪酸(C18)的物种。总之，它的许多健康益处可能是由于其高含量的月桂酸。因此，这种油因其营养和健康特性而受到高度重视。
