摘要
目的:对藏药髯花杜鹃花挥发油的化学成分进行研究。方法:采用水蒸气蒸馏法提取髯花杜鹃花的挥发油,用毛细管气相色谱-质谱联用技术对化学成分进行分析,以面积归一法测定各个成分的相对百分含量。结果:共分离出50个峰,鉴定了其中47个化学成分,占挥发油总量的97.44%。结论:髯花杜鹃花挥发油中的主要成分为N-乙酰-1,2,3,4-四氢异喹啉(29.23%)、2-乙氧丙烷(12.47%)、3-甲基-6-叔丁基苯酚(10.83%)、3-甲基-5-苯基异噻唑(6.38%)、二苯胺(4.20%)、N-乙基-1,2,3,4-四氢萘胺(3.62%)、二十五烷(3.12%)、二十三烷(3.06%)等。
Objective： To study the chemical constituents of the volatile oils from the flowers of Rhododendron anthopogon D.Don.Methods： The volatile oils from the flowers of Rhododendron anthopogon D.Don were extracted by water steam distillation and its chemical constituents were separated and identified by GC-MS.The content of each constituent was determined by area normalizetion method.Results： Fifty peaks were separated and forty seven components were identified,which constituted about 97.44% of the total essential oils.Conclusions： The main compounds are N-acetyl-1,2,3,4-tetrahydro-isoquinoline（29.23%）,2-Ethoxypropane（12.47%）,3-Methyl-6-tert-butylphenol（10.83%）,3-Methyl-5-phenyl-isothiazole（6.38%）,Diphenylamine（4.20%）,N-ethyl-1,2,3,4-tetrahydro-naphthalenamine（3.62%）,Pentacosane（3.12%）and Tricosane（3.06%）.
