摘要
采用红外辅助蒸馏-顶空固相微萃取方法萃取干白芷中的挥发油,并用气相色谱质谱方法分析了其成分,与传统的顶空固相微萃取方法比较,该方法具有萃取时间短、萃取效率高的优点,可用于干中草药挥发油的快速分析。
In this work,for the first time,two solvent-free sample preparation techniques of infrared distillation and headspace solid-phase microextraction were combined,and developed for determination of essential oil components in dry Radix Angelicae dahuricae.To demonstrate the method feasibility,the conventional headspace solid-phase microextraction method was also used for the analysis of essential oil in the same samples.Compared to conventional headspace solid-phase microextraction,the advantages of the proposed method are： short extraction time and high extraction efficiency.It was found that the proposed method is an alternative tool for fast analysis of essential oil in dry Traditional Chinese medicines.
