摘　　要：目的:分析毛白杜鹃花挥发油化学成分。方法:采用水蒸气蒸馏法提取毛白杜鹃花挥发油,利用气相色谱-质谱联用分析挥发油化学成分。结果:共鉴定出49种化学成分,占挥发油总量的79.55%,含量较高的成分有芳樟醇、β-桉叶烯、植物醇、苯甲酸苄酯、水杨酸苄酯、壬醛等。结论:毛白杜鹃花挥发油以萜类、酯类、烷烃为主,含有多种生物活性成分。Objective： To analyze the chemical constituents of volatile oil from flowers of Rhododendron mucronatum. Methods： The volatile oil was extracted by water-steam distillation and analyzed by GC-MS. Results： Forty-nine compounds, which occupied 79. 55% of total constituents, were identified. The major constituents were linalool, β-eudesmene, phytol, benzyl benzoate, benzyl salicylate and nonyl aldehyde. Conclusion： The chemical constituents of volatile oil, which contain many bioactive constituents, are mainly composed of terpenes, esters, and alkanes.
