海南产粗根茎莎草挥发油化学成分的GC-MS分析

摘要

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,5,6,7,8-hexahydro-4a,5-dimethyl-3- (1-methylethylidene) -, (4ar-cis) - (19.48%), 2 (1H) Naphthalenone,3,5,6,7,8,8a-hexahydro-4,8a-dimethyl-6- (1-methylethenyl) - (16.59%).
