云南松松针挥发性成分的气相色谱-质谱分析

目的：研究云南松松针挥发油的化学成分，为进一步开发和利用该资源提供科学依据。方法：采用水蒸气蒸馏法提取云南松松针挥发油，经气相色谱-质谱联用技术分析其成分，采用峰面积归一化法测得各组分的相对百分含量。结果：从中鉴定出45个组分，占峰面积的84．14％。结论：云南松松针挥发性成分主要为α-蒎烯（14．74％），脱氢-4-表松香酸（11．67％），2，7-二羟基-3，4，6-三甲氧基-9，10-二氢菲（8．41％），石竹烯（6．91％），乙酸冰片酯（5．63％），D-柠檬烯（4．55％），1，6-杜松二烯（4．16％）等。

Analysis of Volatile Oil Constituents in Pine Needle of pinus yunnanensis by Gas Chromatography - Mass Spectrometry

Objective： To study the chemical components of volatile oil in pine needle of pinus yunnanensis, and provide the scientific basis for exploitation. Method： The volatile oil constituents were extracted by steam distillation from pine needle of pinus yunnanensis, and analyzed by GC - MS. The relative contents of each constituent was calculated using square peaks to normalization. Result： 45 compounds.were identified, accounting for 84. 14% of the total area of the peaks. Conclusion ： The main volatile oil constituents in pine needle of pinus yunnanensis were α - pinene （ 14.74% ） , dehydro -4 - epiabietic acid （ 11.67% ） , 2, 7 - di- hydroxy - 3, 4, 6 - trimethoxy - 9, 10 - dihydrophenanthrene （ 8.41% ）, caryophylene （6. 91% ）, bornyl acetate （5. 63% ）, D - limonene （4. 55% ）, 1, 6 - cadinadiene （4. 16% ）, etc.
