摘要

摘要: 目的：研究香柏挥发油的化学成分，为香柏的开发利用提供理论依据。方法：采用水蒸气蒸馏法提取香柏挥发油，用GC毛细管柱进行分析，归一化法测其相对含量，并用气相色谱-质谱法对化学成分进行鉴定。结果：共初步鉴定出79个化合物，鉴定出的化合物含量占总挥发油的93.78%。结论：香柏挥发油主要成分为α-杜松醇(相对含量为16.70%)；α-小茴香烯(14.98%)；3，7，11-甲基-2，6，10-十二碳三烯-1-醇(6.49%)；1-甲基-4-［1-甲基乙基］-1，4-环己二烯(4.74%)；贝壳杉-5，16-二烯-18［或19］-醇(3.62%)；α，α，4a，8-四甲基-1，2，3，4，4a，5，6，7-八氢- 2-甲醇萘(3.04%)；［+］-4-蒈烯(2.81%)；D-柠檬烯(2.71%)；β-月桂烯(2.59%)；雪松醇(2.40%)；α-蒎烯(2.36%)；1，1，4a-三甲基-7-异丙基-1，2，3，4，4a，9，10，10a-八氢菲(2.32%)。

Abstract: Aim ：To provide the foundation for reasonable utilization by analyzing the essential oils of Sabina pingii var.wilsonii.. Methods ：The essential oils were extracted using steam distillation and separated with GC capillary column.The components were quantitatively determined with normalization method，and were preliminarily identified by GC-MS. Results ：79 Components were identified，which took up 93.78% of the essential oils. Conclusion ：The main components of essential oils were α-terpineol(16.70%)；α-fenchene(14.98%)；2，6，10-dodecatrien-1-ol，3，7，11-trimethyl-(6.49%)；1，4-cyclohexadiene，1-methyl-4-［1-methylethyl］-(4.74%)；kaura-5，16-dien-18［or19］-ol(3.62%)；naphthalenemethanol，1，2，3，4，4a，5，6，7-octahydro-α，α，4a，8-tetramethyl-，［2R-cis］-(3.04%)；［+］-4-carene(2.81%)；D-limonene(2.71%)；β-myrcene(2.59%)；cedrol(2.40%)；α-pinene(2.36%)；7-isopropyl-1，1，4a-trimethyl-1，2，3，4，4a，9，10，10a-octahydrophenanthrene(2.32%).
