GC-MS分析不同贮藏条件对吴茱萸挥发油成分的影响

目的分析不同贮藏时间及条件对吴茱萸挥发油化学成分的影响。方法采用水蒸气蒸馏法从吴茱萸中提取挥发油,用归一化法测定各组分的质量分数,并用气相色谱-质谱法对其化学成分进行鉴定。结果共鉴定了99种化合物,占挥发油总成分的85%以上。不同贮藏时间及条件对吴茱萸挥发油含量影响较大。结论本实验稳定可靠,重现性好,适用于吴茱萸挥发油的化学成分分析,为吴茱萸合理贮藏及临床应用“陈久者良”提供科学依据。

GC - MS Analysis of the Effect of Storage Time and Condition on the Volatile Components of Fructus Evodia

Objective To observe the influence of storage time and condition on the chemical components in the volatile oil of Fructus Evodia by GC-MS.Methods The volatile oil was extracted from Fructus Evodia by steam distillation and the amount of each components in the volatile oil was determined by area normalization method and the components were identified by GC-MS.Results One hundred and sixteen components were separated and identified,which accounted for more than 90% in the total constitutes of the volatile oil.The content of volatile oil in Fructus Evodia was influenced by the storage time and condition.Conclusions The method is reliable and has a good repeatability,and can be applied to analyze volatile components in Fructus Evodia.This will provide a certain scientific basis for the storage and clinical application of Fructus Evodia.
