摘　　要：[目的]对藏产鳞腺杜鹃地上部分挥发油的化学成分进行研究。[方法]采用水蒸气蒸馏法提取鳞腺杜鹃地上部分的挥发油,用毛细管气相色谱-质谱联用技术(GC-MS)对其化学成分进行分析。[结果]共分离出64个色谱峰,鉴定了其中60个化学成分,占挥发油总量的98.70%。其中,主要成分有α-蒎烯(18.30%)、柠檬烯(14.85%)、萘(11.78%)、β-蒎烯(8.81%)、γ-松油烯(5.54%)、反式丁香烯(4.57%)、橙花叔醇(3.19%)、间伞花烃(2.99%)、氧化石竹烯(2.37%)和β-月桂烯(2.03%)等。[结论]鳞腺杜鹃地上部分的挥发油化学成份为首次报道,为鳞腺杜鹃的充分开发利用提供了科学依据。[Objective]The research aimed to study the chemical constituents in the volatile oils from the aerial parts of tibetan Rhododendron lepidotum Wall.ex G.Don.[Method]The volatile oils in the aerial parts of Rhododendron lepidotum Wall.ex G.Don were extracted by water steam distillation and its constituents were identified by GC-MS method.[Result]A total of 64 chromatographic peaks were separated and 60 components were identified,occupying 98.70% of total amount.The main compounds included alpha-Pinene（18.30%）,Limonene（14.85%）,Naphthalene（11.78%）,beta-Pinene（8.81%）,gamma-Terpinene（5.54%）,trans-Caryophyllene（4.57%）,Nerolidol （3.19%）,m-Cymene（2.99%）,Caryophyllene oxide（2.37%）,beta-Myrcene（2.03%）,etc.[Conclusion]The volatile oils in the aerial parts of Rhododendron lepidotum Wall.ex G.Don was reported for the first time,which provided a scientific basis for fully developing and utilizing Rhododendron lepidotum Wall.ex G.Don.
