摘　　要：采用水蒸气蒸馏法从广西柳州产新鲜马尾松和湿地松松针中提取挥发油,利用气相色谱-质谱(GC/MS)联用技术分别对两树种松针挥发油的化学成分进行分析。从马尾松松针挥发油中分离出96种化学成分,鉴定了其中的35种成分,占挥发油总离子流的93.13%;从湿地松松针挥发油中分离出133种化学成分,鉴定了其中的38种成分,占挥发油总离子流的88.83%。两树种松针挥发油的主要化学成分大致相似,主要是单萜和倍半萜,以及少量萜烯的醇、酯类化合物,但在含量上有较大的差别。马尾松松针挥发油中α-蒎烯的含量约为湿地松的3倍,而后者的β-蒎烯含量是前者的1.29倍。Volatile oils were extracted by steam distillation from fresh leaves of Pinus massoniana and Pinus elliottii Engelm grown in Guangxi Liuzhou, and the chemical components of volatile oils were analyzed by gas chromatography-mass spectrometry （GC/MS）. 96 components in the volatile oils from leaf of Pinus massoniana were separated, and 35 of them were identified, which accounted for 93.13%. 133 components in the volatile oils from leaf of Pinus elliottii Engelm were separated, and 38 of them were identified, which accounted for 88.83%. Generally, the components of volatile oils from leaves of the two varieties are similarity. The main compounds are monoterpinenes, sesquiterpenes and some alcohol, esters, but the contents of some compounds are difference greatly. The content of α-pinene in the volatile oils from Pinus massoniana leaves is 3 times as that from Pinus elliottii Engelm leaves, and the content of β-pinene from the latter is 1.29 times as that from the former.
