设计了一种简易同时蒸馏萃取(SSDE)装置并用于八角茴香挥发油提取及其气相色谱-质谱法(GC-MS)分析。该装置由圆底烧瓶、恒压滴液漏斗和回流冷凝管构成。通过对八角茴香挥发油组分的GC-MS分析, 比较SSDE法和水蒸汽蒸馏提取法(HD)提取植物源挥发油的效果。结果表明, SSDE法所得挥发油相对含量在0. 1%以上的19种化合物占挥发油总量的98. 84%(相对标准偏差(RSD)(n=3)均不大于5. 59%, 其中RSD ﹤ 5%的17种化合物占鉴定组分89. 5%。SSDE法和HD法挥发油平均收率分别为7. 30%(RSD=2. 37%(n=5))和6. 67%(RSD = 5. 26%(n=5))。SSDE法简便、快速, 适用于八角茴香挥发油的提取。

A simple simultaneous distillation and solvent extraction （SSDE） method was developed and had been applied for sample preparation of the gas chromatography-mass spectrometry（GC-MS） analysis of volatile components from Illieium Verum. The simple apparatus was composed of a round flask, a constant pressure dropping funnel and a condenser. The constituents of the volatile oil obtained by SSDE were compared with those obtained by hydrodistillation method（HD） followed by GC-MS analysis. In terms of GC-MS analysis of volatile oil, the relative ...
