代代花挥发油化学成分的GC-MS研究

A Study on Chemical Constituents of the Essential Oil From Citrus Aurantium‘Daidai’ by GC-MS

采用水蒸气蒸馏法从代代花中提取挥发油 .试用不同类型的毛细管柱进行分析 ,找出最佳分析条件 ,用归一化法测定其百分含量 ,用气相色谱 质谱法对代代花挥发油进行化学成分的分析 .共鉴定了 39个成分 ,占挥发油总成分的 86 %以上 .本方法稳定可靠 ,重现性好 ,适用于中药挥发油的化学成分分析 .

The essential oil was extracted from Citrus aurantium‘Daidai’ by steam distillation.The components were analyzed with different kinds of capillary columns.The optimum separating and analytical conditions were researched.The amount of the components from the essential oil were determinated by the normalization method.The components separated were identified by GC MS.There were 39 components in about 86% of the total essential oil,which were separated and identified.The method is reliable,stable and has good repeatability,this method can be applied to the analysis of the essential oil components extracted from traditional Chinese medicines.
