摘要
通过气相色谱-质谱联用(GC-MS)测定椰子果肉中的脂肪酸含量,用外标法进行定量分析。椰子果肉脂肪酸种类丰富,选取常见的4种脂肪酸,在椰子果肉中的含量:棕榈酸〉油酸〉硬脂酸,亚油酸未检出。相对标准偏差RSD(n=5)在2.03%~10.25%之间,样品回收率测定在77.0%~110.0%之间。
The fatty acid in coconut flesh were analyzed by GC-MS,using the external standard method to analyze quantitatively. There are different kinds of fatty acid in coconut flesh. The content of the four fatty acids in coconut flesh: Palmitic acid 〉 oleic acid 〉 stearic acid, Linoleic acid was not checked out. The RSD of results was between 2.03 % and 10.25 % .The recovery rate of sample was from 77.0 % to 110.0 %.
