Fatty Acids Analysis in Decaisnea insignis and Akebia trifoliate Seed Oil by GC-MS

The fatty acids from the seeds oil of Decaisnea insignis and Akebia trifoliata were extracted with petroleum ether by Soxlet extraction.The extracted fatty acids were esterified and then analyzed by gas chromatographymass spectrometry.Nine fatty acids amounting to 94.67%(the saturated fatty acid and unsaturated fatty acid were 12.63% and 82.04%,respectively)of the total contents detected were identified in D.insignis seed oil.The main components were 9-hexadecenoic acid(47.22%),9-octadecenoic acid(27.13%),hexadecanoic acid(10.75%),9,12-octadecadienoic acid(7.47%),and octadecanoic acid(1.61%).Ten fatty acids amounting to 99.75%(the saturated fatty acid and unsaturated fatty acid were 23.39% and 76.36%,respectively)of the total contents detected were identified in A.trifoliata seed oil.The main components were 11-octadecenoic acid(47.63%),9,12-Octadecadienoic acid(27.05%),hexadecanoic acid(20.14%),16-methyl-Heptadecanoic acid(3.03%),and 8-Octadecenoic acid(1.07 %).The results showed the content of fatty acids was more abundant in seed oil of D.insignis and A.trifoliata in plants of Lardizabalaceae,and their seeds had a great range of potential utilities and a prospect of development in foods,medical and health cares.
