Supercritical CO2 Fluid Extraction of Trachycarpus fortunei Seed Oil and GC-MS Analysis

Abstract

Abstract: The seed oil of palm(Trachycarpus fortunei) harvested from two sampling places of West Hunan province was extracted by supercritical CO2 fluit extraction technology,and its components was analyzed by GC-MS.The results showed that the optimal process conditions are as follows:extraction pressure 30 MPa,temperature 45 ℃,and time 2 h.The oil yield is 14.6% under the above conditions.According to GC-MS results,there are eight and seven kinds of fatty acid in Trachycarpus fortunei seed oil from the two sampling places,respectively.The common components of the two seed oils are 10,13-octadecadienoic acid(36.58%),(z)-9-octadecenoic acid(29.93%),hexadecanoic acid(13.22%),dodecanoic acid(8.74%),methyl tetradecanoate(6.62%),octade-canoic acid(2.63%) and(z)-9-hexadecenoic acid(1.28%).Trachycarpus fortunei seed oil contains abundant unsaturated fatty acids,which can be used as edible oil and industrial oil after refinement.

Key words: Trachycarpus fortunei, seed oil, supercritical CO2 fluid extraction, gas chromatography-mass spectrometry(GC-MS)
