摘要
目的:研究拉雅松和细叶云南松松针挥发油的化学成分。方法:采用水蒸汽蒸馏法从拉雅松和细叶云南松松针中提取挥发油,利用气相色谱-质谱联用技术分析挥发油的化学成分。结果:从拉雅松松针挥发油中鉴定出62个化合物,占挥发油总量的95.565%,主要成分为α-蒎烯(24.659%)、β-蒎烯(11.471%)、β-石竹烯(9.932%)和异松油烯(5.167%);从细叶云南松松针挥发油中鉴定出55个化合物,占挥发油总量的90.794%,主要成分为α-蒎烯(22.542%)、β-石竹烯(16.636%)和1,2,4a,5,8,8a-六氢化-4,7-二甲基-1-(1-甲基乙基)-萘(5.085%)。结论:首次研究了拉雅松和细叶云南松松针挥发油的化学成分,为合理开发利用广西的松针资源提供了科学依据。
Objective：To study the chemical constituents from pine needle of Pinus crassicorticea and P.yunnanensis Franch.var tenuifolia.Method：The essential oils from Pinus crassicorticea and P.yunnanensis Franch.var tenuifolia were extracted by steam distillation.The volatile components were analyzed by gas chromatography-mass spectrometry（GC-MS） methods.The relative contents of these constituents were calculated by peak area normalization.Result：Sixty two compounds in the essential oil from P.crassicorticea were identified,counting for 95.565% of the total area of the peaks.The principal constituents were α-pinene（24.659%）,β-pinene（11.471%）,β-caryophyllene（9.932%） and terpinolene（5.167%）.55 compounds in the essential oil from P.yunnanensis Franch.var tenuifolia were identified,counting for 90.794% of the total area of the peaks.The principal constituents were α-pinene（22.542%）、β-caryophyllene（16.636%） and 1,2,4a,5,8,8a-hexahydro-4,7-dimethyl-1-（1-methylethyl）-naphthalene（5.085%）.Conclusion：The essential oils from pine needle of P.crassicorticea and P.yunnanensis Franch.var tenuifolia were investigated for the first time.It had provided scientific foundation for exploitation and utilization of P.crassicorticea and P.yunnanensis Franch.var tenuifolia.
