海南产粗根茎莎草挥发油化学成分的GC-MS分析

GC-MS Analysis of the Volatile Oils from Cyperus stoloniferus Retzius in Hainan

采用常压水蒸气蒸馏法提取粗根茎莎草(Cyperus stoloniferus)的挥发油,经GC-MS分析,从挥发油中鉴定出17种化合物,占总油量的99.66%。其中含量较高的为苯二甲酸(2-乙基-己基)酯(29.39%)、4,4α,5,6,7,8-六氢化-4α,5-二甲基1-3(1-甲基乙基)2(3H)-萘酮(19.48%)、3,5,6,7,8,8a-六氢化-4,8a-二甲基乙烯基-2(1H)萘酮(16.59%)。

The volatile oils were extracted from Cyperus stoloniferus by means of steam distillation. Seventeen compounds were identified from the oils by GC-MS analysis , accounting for 99.66% of the total volatile oils. The major constituents were Bis （2-ethylhexyl） phthalate （29.39%）, 2 （3H） -Naphthalenone,4,4a,5,6,7,g-hexahydro--4a,5- dimethyl-3- （1-methylethylidene） -, （4ar-cis） - （19.48%）, 2 （1H） Naphthalenone,3,5,6,7,8,Sa-hexahydro-4,8a- dimethyl-6- （1-methylethenyl） - （16.59%）.
