气相色谱-质谱法分析无籽罗汉果果实中挥发油成分

Analysis of volatile oil from seedless fruits of Siraitia grosvenorii by gas chromatography-mass spectrometry

采用水蒸气蒸馏法提取无籽罗汉果果实中的挥发油,经气相色谱-质谱联机分析,鉴定出挥发油中的24个化学成分。其主要成分为:乙二醇异丙醚(27.21%)、1,2-苯二甲酸丁基-2-乙基己酯(13.51%)、邻苯二甲酸二异丁酯(10.85%)、天竺葵醛(10.22%)、(E)3-癸烯酸(6.52%)、丁酸丁酯(4.99%)、乙酸-2-十三烷酯(4.86%)等。与普通罗汉果挥发油成分进行对比发现,其组成与普通罗汉果挥发油相似,但是含量有所变化。测试结果可为进一步开发无籽罗汉果挥发油提供一定基础。

The volatile oil from the seedless fruits of Siraitia grosvenorii was extracted by the hydrodistillation method,in which 24 compounds had been identified by GC-MS.The results showed that the main components were ethanol-2-isopropoxy（27.21%）,1,2-benzenedicarboxylic acid,butyl-2-ethylhexylester（13.51%）,1,2-benzenedicarboxylicacid,bis（2-methylpropyl） ester（10.85%）,nonanal（10.22%）,E-3-decenoic acid（6.52%）,butyl butyrate（4.99%）,2-acetoxytridecane（4.86%） etc.Compared with the data of the volatile oil from conventional Siraitia grosvenorii,the main ingredient contents of seedless Siraitia grosvenorii were different.The results provided scientific proof for further development of the volatile oil of the seedless Siraitia grosvenorii.
