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。
通過氣相色譜-質譜聯用(GC-MS)測定椰子果肉中的脂肪痠含量,用外標法進行定量分析。椰子果肉脂肪痠種類豐富,選取常見的4種脂肪痠,在椰子果肉中的含量:棕櫚痠>油痠>硬脂痠,亞油痠未檢齣。相對標準偏差RSD (n=5)在2.03%~10.25%之間,樣品迴收率測定在77.0%~110.0%之間。

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%.
