艾叶挥发油与燃烧烟雾的化学成分比较

艾叶燃烧产生的烟雾有艾灸、消毒驱虫等效果,为探究其活性物质,选用甲醇吸收其烟雾,通过气相色谱-质谱联用(GC-MS)分析其化学成分,并与艾叶活性成分——挥发油的GC-MS结果进行比较.研究表明:艾叶燃烧烟雾中含有与其挥发油相同的成分,包括4-羟基-4-甲基-2-戊酮、1,8-桉油精、龙脑、侧柏酮、β-石竹烯、2,2’-二噻吩、3,3,6,8-四甲基-1-四氢萘酮和6-芹子烯-4-醇;1,8-桉油精和β-石竹烯是艾叶熏蒸和燃烧消毒驱虫的有效成分,1,8-桉油精、龙脑、侧柏酮、β-石竹烯等可能是艾灸时进入人体内发挥药效作用的活性成分.

Comparison of Chemical Constituents Between Essential Oil and Smog from Artemisia argyi

The smog from the flaming leaves of Artemisia argyi has the effects of moxibustion,disinfection and desinsectization.In order to find out the active substances of Artemisia argyi,methanol was used to absorb the smog,and the chemical constitutes in both the absorption liquid and the effective essential oil from Artemisia argyi were analyzed and compared by means of GC-MS.The results indicate that both the smog and the essential oil are of the same chemical constituents such as 4-hydroxy-4-methyl-2-pentanone,eucalyptol,borneol,thujone,β-caryophyllene,2,2′-bithiophene,3,3,6,8-tetramethyl-1-tetralone and selina-6-en-4-ol,that eucalyptol and β-caryophyllene are two active substances for moxibustion,disinfection and desinsectization,and that eucalyptol,borneol,thujone and β-caryophyllene in the smog may enter human body and play various bioactive role through moxibustion.
