摘要: 采用水蒸汽蒸馏法和毛细管气相色谱—质谱联用法对野生杜鹃挥发性化学成分进行了分析,
分离出83 个峰, 确认了其中的77 种化合物, 其含量共占全油的98. 63 % , 其主要化学成分为5 - 羟基- 2- 甲基苯甲醛; 2 - 氟苯基异氰酸盐; 5 - 乙基- 5 - 甲基- 环己酮; 1 - 乙基- 1 - 甲基- 环己烷; 4α- 甲基- 十氢萘; β- 榄香酮; 1 , 2 , 3 , 5 , 6 , 7 , 8 , 8α- 八氢萘等。

Abstract: The essential oil from Rhododendron thymifolium Maxim. was abstracted by steam-stilling and analyzed by capillary GC-MS method. By capillary chromatography , more than 83 peaks were isolated , and 77 compounds of them were identified , the identification rate was 98. 63 %. The relative percentages of the constituents were determined by GC method , and the main chemical component parts of the oil were 5-Hydroxy-2-methyl benzaldehyde ; 22Fluorophenyl isocyanate ; Cyclohexanone , 5-ethenyl-5-methyl-; Cyclohexane , 1-ethenyl-1-methyl-; Naphthalene , decahydro-4α-methyl-; β-Elemenone ; Naphthalene , 1 , 2 , 3 , 5 , 6 , 7 , 8 , 8α-octahydro- and
etc. The study provided solid and scientific proof for the further development of Rhododendron thymifolium Maxim.

Key words: Rhododendron thymifolium Maxim., Essential oil, GC-MS
