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.
