摘要: 利用超临界CO2流体萃取技术提取了湘西地区两个采样点的棕榈树种仁油,并对其化学成分进行了气相色谱质谱联用(GC-MS)分析。结果表明,棕榈树种仁油超临界CO2萃取的最佳工艺条件为:萃取压力30MPa、萃取温度45℃、萃取时间2h,在此条件下的萃取率为14.6%。GC-MS检测出两个采样点的种仁油脂肪酸成分分别为8种和7种。其共同的成分为10,13-十八碳二烯酸(36.58%)、油酸(29.93%)、棕榈酸(13.22%)、月桂酸(8.74%)、肉豆寇酸(6.62%)、硬脂酸(2.63%)和顺式-9-十六碳烯酸(1.28%)。棕榈树的种仁油含不饱和脂肪酸高,精炼后可以作为食用油和工业用油开发。

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.
