摘　　要：研讨香格里拉县小叶杜鹃花的挥发油化学成分,为进一步合理开发利用其药用资源提供试验依据。利用水蒸汽同时蒸馏萃取法(SDE)提取小叶杜鹃花的挥发性化学成分,通过气相色谱-质谱联用技术(GC-MS)对各个色谱峰定性,并采用色谱峰面积归一法获得各个化合物的相对含量。从小叶杜鹃花挥发油中共分离鉴定了73个色谱峰,占挥发油总量的85.53%。小叶杜鹃花挥发油主要成分有α-蒎烯(14.00%)、正二十三烷(9.51%)、7-甲氧基-2,2-二甲基-3-色烯(6.26%)、正二十烷(6.11%)、苯乙醇(5.10%)、1-Heneicosyl formate(4.60%)等。The first study was to explore the chemical compounds of essential oil from Rhododendron parvifolium Adams in Shangri-La county,and provide the test basis for further rational exploitation and utilization of its medicinal resources.The chemical composition of essential oil of R.parvifolium was extracted by simultaneous distillation and solvent extraction and analyzed by gas chromatography-mass spectrometry（GC-MS）.The relative contents of each component in the volatile oil were obtained by normalization of peak areas.73 chromatographic peaks were separated and identified which took up 85.53%in the essential oil from R.parvifolium.The main components of essential oil from R.parvifolium were alpha-pinene（14.00%）,N-tricosane（9.51%）,7-methoxy-2,2-dimethyl-3-chromene（6.26%）,N-eicosane（6.11%）,phenethyl alcohol（5.10%）,1-heneicosyl formate（4.60%）etc.
