甘青青兰挥发油成分超临界二氧化碳萃取与气相色谱-质谱分析

采用超临界CO2萃取法从甘青青兰中提取挥发油,用气相色谱-质谱法鉴定其化学成分和相对含量.38种化合物被鉴定,主要成分为桉油醇、(1α,2α,5α)-2,6,6-三甲基二环3.1.1]-3-庚酮、α,α,4,8-四甲基-3,7-环癸二烯-1-甲醇、1,6-二甲基-9-(1-甲基亚乙烯基)-5,12-二氧杂三环9.1.0.0(4,6)-8-十二烷酮、(E,E)-3,7-二基-10-(1-甲基亚乙烯基)-3,7-环癸二烯-1-酮等;乙醇作携带剂超临界CO2萃取挥发油44种化合物被鉴定,主要成分为桉油醇、(1α,2α,5α)-2,6,6-三甲基二环3.1.1]-3-庚酮、1R-(1α,3α,4β)]-α,α,4-三甲基-4-乙烯基-3-(1-甲基乙烯基)-环已烷甲醇、(E,E)-3,7-二甲基-10-(1-甲基亚乙烯基)-3,7-环癸二烯-1-酮、乙酸等.

Study on Chemical Constituents of Essential Oil From Dracocephalum Tangicum Maxim by Supereritical Carbon Dioxide Extraction /Gas Chromatography-Mass Spectrometry

Essential oils were extracted from Dracocephalum tangicum.Maxim by Supercritical carbon dioxide extraction(SFE-CO2).Their components were analyzed by gas chromatography-mass spectrometry(GC-MS).Thirty-eight compounds were identified for the essential oil obtained by SFE-CO2,and its main components have been found to be eucalyptol,bicycloheptan-3-one,2,6,6-trimethyl-,(1alpha,2alpha,5alpha),3,7-cyclodecadiene-1-methanol,alpha,alpha,4,8-tetramethyl-,1,6-Dimethyl-9-(1-methylethylidene)-5,12-dioxa tricycle 9.1.0.0(4,6)] dodecan-8-one,(E,E)-3,7-cyclodecadien-1-one,3,7-dimethyl-10-(1-methylethylidene);44 compounds were identified for the essential oil obtained by SFE-CO2 while adding alcohol,and there are mainly eucalyptol,bicycloheptan-3-one,2,6,6-trimethyl-,(1alpha,2alpha,5alpha),cyclohexanemethanol,4-ethenyl-alpha,alpha,4-trimethyl-3-(1-methylethenyl)-1R-(1alpha,3alpha,4beta)],(E,E)-3,7-dimethyl-10-(1-methyl-vinylidene)-3,7-cyclodecadiene-1-ketone,acetic acid,and so on.
