四川杜鹃花中挥发性成分的研究

Study of volatile components of the essential oil from the flower of Rhododendron Sutchuenense

水蒸气蒸馏法从四川杜鹃的花中提取挥发油,用气相色谱-质谱联用技术对其挥发油化学成分进行分离和结构鉴定,从四川杜鹃的花挥发油中总共分离出53个组分,鉴定出51个组分。用气相色谱面积归一化法确定了各个组分的相对百分含量,其挥发油主要组分是石竹烯(12.48%)、愈创醇(8.83%)、α-蒎烯(8.32%)、β-蒎烯(7.78%)、β-紫罗兰酮(6.83%)等。

The essential oil fi＇orn the flower of Rhododendron Sutchuenense was extracted by steam distillation, and the components of the essential oil were separated and structurally identified by gas chromatography/mass spectrometry. The relative contents of the components by the peak - area normalization method was adopted in gas chromatography, 53 components were separated, 51 components were identified. The major components of the essential oil were Caryophyllen（ 12.48% ） , Guaiol（ 8.83% ） , α - Pinene（ 8.32% ）, β - Pinene（7.78% ）,β - Lonone（6, 83% ） ,etc.
