Release rule of volatile components of moxa sticks with increase of temperature
摘要
目的:系统考察艾条在不同顶空温度及燃烧条件下释放出的挥发组分组成及其主要组分的变化规律,指导临床合理选择艾条的使用温度。方法:采用顶空-气相色谱质谱联用技术(HS-GCMS),将艾条置于顶空温度为室温(25℃)至190℃及艾条燃烧条件下,收集其释放出的气体,取其1 m L注入6890/5973N型气相色谱质谱联用仪(GCMS)。通过总离子色谱图(TIC)及丁酮内标法,计算艾条挥发性组分释放率;通过分析各挥发性组分的质谱图以及进行Nist 14标准质谱库匹配,定性分析各艾条挥发性组分;通过对比分析1
