千里香杜鹃挥发性成分的分析研究

Studies on the Essential Constituent of Rhododendron thymifolium Maxim.

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 98.6 3 %,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。

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; 2-Fluorophenyl 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.
