不同储存年份的艾条燃烧生成自由基的 ESR 波谱研究
A study on ESR Spectrum of the Free Radicals Produced by Burning Moxa Stick in Different Years
摘要
Abstract
Objective:To observe the changes of species and contents of free radicals generated by burning moxa with different storage time, and discuss the security of moxa from free radicals perspective .Methods:Detected and analysed free radicals in burning Qichun moxa sticks with 1 year, 3 years, 5 years storage time respectively using electron spin resonance (ESR) technique.Results:1) Free radicals were detected in both tar and gas phase of burning moxa , mainly quinone/semiquinone radicals in tar and alkyl , alkoxy, NO radicals in gas;2) the signal intensity of all detected free radicals in burning moxa with 3 years and 5 years storage time was inferior to it in 1 year moxa(P<0.05, P<0.01), quinone/semiquinone radicals, alkyl and alkoxy radicals had no difference between burning 3 years moxa sticks and 5 years moxa sticks (P>0.05), while the signal intensity of NO radicals in 5 years moxa was under that in 3 years moxa(P<0.01).Conclusion:The free radicals generated from burning moxa mainly were quinone /semiquinone radicals, alkyl and alkoxy radicals, and NO radicals, free radicals mentioned above were less in burning moxa with 3 years and 5 years storage time than that in 1 year storage time moxa.The detection of free radicals might become an important evaluation basis for identification of moxa with different storage time and moxibustion security authentication .关键词
