| 摘 要： | 为探索研究油松的新方法，该文应用超临界CO2萃取技术，以油松针叶为材料萃取萜烯类化合物，以α 蒎烯、β石竹烯为研究的重点，采用单因子变化的实验方法，通过GC和GC/MS监测，改变萃取时间、萃取压力、萃取温度，找到最佳实验条件. 实验结果表明，萃取压力15 MPa、萃取温度40℃和萃取时间20 min，是从油松针叶中萃取以α蒎烯和β 石竹烯为代表的萜烯类化合物得率较高的萃取条件.与水蒸气蒸馏相比，该实验方法省时且样品收率高.

| Abstract: | Supercritical carbon dioxide extraction is an advanced technique in extracting volatile substances，which works at low temperatures，without any oxidation and deterioration.This method was first used to extract volatile terpenoids, suchas α pinene and β caryophyllene, from the needles of Pinus tabulaeformis by means of alternating the factors of extraction pressure，temperature and time, and by GC and GC/MS monitoring. Results show that the optimum extraction conditions including the pressure of 15 MPa， temperature of 40℃ and the time of 20 min.Compared with the former method of vapour distillation，the duration of this method is shorter and extraction efficiency is higher. |
