【摘要】 [目的]探讨中药荔枝草挥发油的化学成分,进一步揭示其药理作用。[方法]采用水蒸气蒸馏法从荔枝草中提取挥发油,利用气相色谱/质谱联用技术(GC-MS)分析荔枝草挥发油的化学成分。[结果]共分离到49个化合物,鉴定了其中的31个,占挥发油总量的87.31%。主要包括1,2,3,4,4a,5,6,8a-八氢-7-甲基-4-次甲基-1-(1-甲基乙基)-萘(17.395%),石竹烯(12.495%),[S-(E,E)]-1-甲基-5-次甲基-8-(1-甲基乙基)-1,6-环癸二烯(11.987%),(1S-顺)-1,2,3,5,6,8a-六氢-4,7-二甲基-1-(1-甲基乙基)-萘(8.843%),α-荜澄茄烯(7.846%)等。[结论]试验所分析的荔枝草挥发油的主要化学成分为萜烯类,与报道的分析结果有一定差别,这可能与荔枝草的产地、采收季节有关。更多还原

【Abstract】 [Objective] The study aimed to discuss the chemical composition of the essential oil from the Salvia plebeia R.Brown and reveal its pharmacological effect further.[Method] The essential oil was extracted from the S.plebeia by steam distillation and then its chemical composition was analyzed by applying GCMS technique.[Result] There were 49 ingredients that were separated in total and 31 of them were identified,accounting for 87.31% of the total essential oil. The main chemical components of the S.plebeia essential oil were: 1,2,3,4,4a,5,6,8a-octahydro-7-methyl-4-methylene-1-(1-methylethyl)-naphthalene(17.395%),Caryophyllene(12.495%),[s-(E,E)]-1-methyl-5-methylene-8-(1-methylethyl)-1,6-Cyclodecadiene(11.987%),(1S-cis)-1,2,3,5,6,8a-hexahydro-4,7-dimethyl1-(1-methylethyl)-Naphthalene-(8.843%),alpha.-Cubebene(7.846%) etc.[Conclusion] The main chemical composition of the essential oil from the Salvia plebeian,analyzed in the test,was terpene and had some diffence with the reported analyzing result,which maybe related with the production area and the picking season.更多还原
