安息香醛

The result indicates that those four resuscitation-inducing aromatic herbs mainly contain volatile oil ,and all contain alicyclic compounds; the volatile oil of Borneolum Syntheticum and Styrax both contain Sesquiterpenes of caryophyllene; as resin herbs , Styrax and Benzoinum both contain vanillin, resin ester and balsamic acid .

结果表明，四味芳香开窍药主含挥发油，均含有脂环化合物，并存在一些共有成分，如龙脑冰片与苏合香挥发油中均含有倍半萜类成分石竹烯；苏合香和安息香皆为树脂类中药，两者均含有香荚兰醛成分，尚含树脂酯，香脂酸等。

by summarizing and analysing the progress on studies of pharmacodynamic material basis of resuscitation-inducing aromatic herbs such as moschus,borneolum syntheticum,styrax,benzoinum, and exploring the generality of those herbs,to provide scientific reference for further studies on the relevance of common substance ,nature and the efficiency of restoring consciousness and inducing resuscitation of those herbs.the result indicates that those four resuscitation-inducing aromatic herbs mainly contain volatile oil ,and all contain alicyclic compounds; the volatile oil of borneolum syntheticum and styrax both contain sesquiterpenes of caryophyllene; as resin herbs , styrax and benzoinum both contain vanillin, resin ester and balsamic acid .

通过对芳香开窍药麝香、冰片、苏合香、安息香的药效物质基础研究进展的整理、分析，探索其共性，拟为深入研究该类药的共性物质—药性—开窍醒神效应之间的关联性提供科学参考。结果表明，四味芳香开窍药主含挥发油，均含有脂环化合物，并存在一些共有成分，如龙脑冰片与苏合香挥发油中均含有倍半萜类成分石竹烯；苏合香和安息香皆为树脂类中药，两者均含有香荚兰醛成分，尚含树脂酯，香脂酸等。

The common chemical constituents were juniper camphor,1,3,3-trimethylcyclohex-1-ene-4-carboxaldehyde,borneol,α-curcumene,α-bisabolol,cis-caryophyllene,benzyl benzoate,methyl β,β-dimethylbenzenepropanoic acid ester,2,4-decadienal and heneicosane in the essential oil of the five cultivars' Hangjuhua.Among them,juniper camphor is most which were composed of 11.96%,10.51%,10.95%,13.28% and 10.77% of the total essential oil,and methyl β,β-dimethylbenzenepropanoic acid ester is second,which were composed of 1.51%,1.86%,2.52%,4.89% and 2.51% of the total essential oil,respectively.

5种栽培类型杭菊花挥发油中共有成分为1，3，3-三甲基环己-1-烯-4-甲醛、冰片、α-姜黄烯、α-甜没药萜醇、顺式石竹烯、桧脑、安息香酸苄酯、β，β-二甲基苯丙酸甲酯、2，4-癸二烯醛和二十一烷；其中桧脑含量最高，分别占挥发油总量的11.96%，10.51%，10.95%，13.28%和10.77%，为5种栽培类型杭菊花挥发油中最具特征的成分；其次是β，β-二甲基苯丙酸甲酯，分别占挥发油总量的1.51%，1.86%，2.52%，4.89%和2.51%。
