摘　　要：运用气相色谱-质谱联用法对香榧子(Torreya grandis)超临界萃取物的挥发性成分进行了分析。采用超临界CO2提取香榧子中脂肪油,总含油量为16.21%。再用气相色谱-质谱联用技术分析萃取物中的挥发性成分,确定香榧子油的脂肪酸组成以亚油酸与油酸为主,质量分数分别为38.228 5%与35.521 9%,其次为棕榈酸和5,11,14-二十一碳烯酸,质量分数分别为7.451 7%与7.405 2%。Torreya grandis was extracted by supercritical fluid extraction and the extracted volatile components were analyzed by gas chromatography coupled with mass spectrometry(GC-MS).Fatty oil was extracted from T.grandis by supercritical CO2,total oil content was 16.21%.10 compounds were found in the extract and the major compounds were 9,12-octadecadienoic acid and 38.228 5%,9-octadecenoic acid 35.521 9%,hexadecanoic acid 7.451 7%,and 5,11,14-eicosadienoic acid 7.405 2%.
