微波提取条件与春砂仁挥发成分的结构分布关系的研究

Study on the relation between the conditions of microwave extraction and the structure distributing of volatile components from Amomum villosum Lour

在温和的微波照射条件下,采用不同溶剂萃取春砂仁中有效成分,低温浓缩为样品。利用固相微萃取(SPME)顶空取样方法,通过GC-MS分析样品中挥发成分,进而研究不同极性、不同沸点的溶剂与春砂仁油树脂中挥发成分的结构分布关系,为提取砂仁油树脂时充分保留其中挥发成分选择最佳条件。结果表明:低极性、低沸点的溶剂萃取砂仁挥发油获得较好的效果,整体提取砂仁油树脂选择乙醚为佳。

Using different solvents for the extraction of volatile components in Amomum villosum Lour by microwave -assisted. Applying the solid phase microextraction （SPME） headspace sampling,the extract was analyzed by CG/MS. The relation of the conditions of microwave extraction and the structure distributing of volatile components from Amomum villosum Lour was studied. The result showed that the low polar and boil solvent were more fit for the extraction of the volatile components in Amomum villosum Lour, It is best when using aether for the extraction of oleoresin in Amomum villosum Lour.
