采用GC-MS联用技术,结合程序升温保留指数,对湖南和四川两个产地的厚朴(分别简称湘朴和川朴)挥发油成分进行分析.共定性出111种挥发油化学成分,湘朴为89种,川朴为88种,分别占二者挥发油总含量的87.74％和92.72％,共有组分66种.厚朴的挥发油主要成分为桉叶醇及其同分异构体.湘朴与川朴挥发油中,α-桉叶醇的含量分别为7.91％和13.34％,β-桉叶醇的含量分别为23.88％和15.75％,y-桉叶醇的含量分别为10.60％和9.68％.湘朴和川朴挥发油成分中含各自的特有组分,分别为23种和22种.二者挥发油成分在化合物含量和种类上存在较大差别.%The essential oil ( EO) of Cortex Magnolia officinalis from Hunan and Sichuan (concisely named Xiangpu and Chuanpu respectively) were comparatively analyzed by GS-MS in combination with temperature-programmed retention indices for the first time. All 111 compounds were identified. Among them 89 compounds of Xiangpu EO were identified and so did 88 of Chuanpu EO, respectively, accounting for 87. 74% and 92. 72% of the total content. The common constituents were 66. The major constituents of the samples studied were eudesmol and its isomers. The contents of α-eudesmol were 7. 91% and 13.34% respectively for Xiangpu and Chuanpu,β-eudesmol were 23. 88% and 15. 75% , γ-eudesmol were 10. 60% and 9. 68% . Their respective compounds are 23 and 22. The contents and compound sorts of the essential ingredients of the two tested samples were varied.
