CGC／IR／MS方法对玫瑰精油化学成分的分析

Analysis of Components of Essential Oil of Rose by CGC/IR/MS Methods

用气相色谱──红外──质谱三联仪（ＣＧＣ／ＩＲ／ＭＳ）研究永登玫瑰精油的化学成分．共分离鉴定了９３个化合物，其中２８个组分为首次鉴定报道．采用标准谱图计算机检索．３６个化合物ＭＳ谱得到ＩＲ谱验证，１５个化合物用标准样对照．比较了永登玫瑰油与保加利亚玫瑰油在组成上的主要差异．

The chemical constituents of the essential oil of roses yielded in YongDeng county of Gansu province, were identified, accounting for 98. 12% of total peak area. 28 compounds in it were first reported. IR spectroscopy of 36 compounds accorded with MS as the data were retrieved from MS/IR spectroscopy library, and 15 compounds were identified by comparing them with standard samples. Some major constituent differences between YongDeng roes and Bualgarian roses were found.
