摘　　要：为了获得杏仁油挥发性成分的最佳萃取条件,以峰总面积和峰个数为评价指标,分别从样品量、萃取温度、萃取时间、解析时间等4个方面,研究了DVB/CAR/PDMS纤维头的固相微萃取条件对甜杏仁油挥发性成分萃取效果的影响。结果表明:样品量为1 g,萃取吸附温度和时间分别为50℃和50 min,进样口解析温度和时间分别为260℃和1 min时,提取的挥发物数量较多,能较好表现出杏仁油的挥发性成分组分。In order to gain the optimal extraction conditions of volatile components from apricot kernel oils, using total peak area and peak number as parameters, the effects of SPME conditions of DVB/CAR/PDMS fiber on volatile components extraction from sweet apricot kernel oils were researched from the aspects of samiple dosage, extraction temperature, extraction time and desorption time. The results show that the number of volatile components extracted is the most and volatile components are more completely revealed under the conditions of 1 g oil sample, extraction for 50 min at 50 ℃, and desorption for 1 min at 260 ℃.
