茅苍术挥发油化学成分的GC/MS分析

采用水蒸气蒸馏法从茅苍术中提取挥发油。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-质谱法对茅苍术挥发油化学成分进行鉴定。共鉴定了57个成分,占挥发油总成分的82％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。

Determination of Chemical Constituents of the Essential Oil from Atractylodes lancea (Thunb. ) DC. by GC-MS

The essential oil was extracted from Atractylodes lancea ( Thunb. ) DC. by steam distillation. The components were analyzed with the different kinds of capillary columns, the optimum separation and analytical conditions were studied, the amount of the components from the essential oil were determinated by normalization method. The components separated were identified by GC-MS. There were 57 components composed in about 82% 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.
