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, beta-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.
目的
分析白花杜鹃花朵挥发油的化学成分。
方法
采用水蒸气蒸馏法提取挥发油，并通过气相色谱-质谱联用仪进行分析。
结果
鉴定出49种化合物，占总成分的79.55%。主要成分有芳樟醇、β-桉叶油烯、叶绿醇、苯甲酸苄酯、水杨酸苄酯和壬醛。
结论
挥发油的化学成分主要由萜类、酯类和烷烃类组成，含有许多生物活性成分。
