采用气-质联用法对杜英叶挥发油的化学成分进行研究,经毛细管色谱分析,共确认出其中的38种成分,所鉴定出化学成分的质量占总量的98.712%。应用色谱峰面积归一法分析各成分的质量分数,含量较高的物质有:α-谷甾醇(15.406%)、沸波醇(14.322%)、α-香树素(13.461%)、3,15,16,21,22,28-六羟基-12-齐墩果烯(11.793%)、3,7,11,15-四甲基-2-十六-烯-1-醇(9.538%)、3-羟基-5,7-雄甾二烯-17-酮(4.519%)等。
The chemical constituents of the essential oil of Eucommia ulmoides leaves were studied by GC-MS, and 38 of them were confirmed by capillary chromatography. The quality of the identified chemical constituents accounted for 98.712% of the total. The mass fractions of each component were determined by the method of normalization of chromatographic peak area. The higher content of the compounds was: α-sitosterol (15.406%), boiling water alcohol (14.322% 15,16,21,22,28-hexahydroxy-12-oleanophenone (11.793%), 3,7,11,15-tetramethyl-2-hexadecen-1-ol , 3-hydroxy-5,7-androstadien-17-one (4.519%) and the like.
