基于全二维气相色谱-四级杆飞行时间质谱高通量检测青花椒挥发性香气成分High-Throughput Detection of Volatile Aroma Components in Zanthoxylum armatum Based on Comprehensive Two-Dimensional Gas Chromatography- Quadrupole Time-of-Flight Mass Spectrometry

摘要(Abstract):
文章采用顶空固相微萃取结合全二维气相色谱-四级杆飞行时间质谱联用的方法,建立一种适用于高通量检测青花椒挥发性香气成分的分析方法,并通过谱库匹配、保留指数及精确质量进行定性确认。结果表明,青花椒中共鉴定出75种挥发性香气化学成分,同时通过乙酸苯乙酯内标相对定量法对贵州、云南和四川不同地区的青花椒样品进行检测,发现青花椒中的主要挥发性香气物质为芳樟醇,其次是β-月桂烯、柠檬烯、β-罗勒烯等萜烯类物质,该方法为青花椒的品质分析和产地鉴别提供了方法参考。
