摘  要：
采用超临界CO2萃取法及常规水蒸汽蒸馏法从瓯柑果皮中提取挥发油,利用气相色谱—质谱联用技术对挥发油化学成分进行分离鉴定,采用峰面积归一化法测定其相对含量。色谱条件:HP-5弹性石英毛细管色谱柱(30 m×0.25 mm,0.25μm);升温程序:初始温度60℃,保持2 min,然后以5℃/min的速度升至240℃并保持30 min;分流进样,分流比50:1;进样口温度280℃。结果采用超临界CO2萃取共鉴定出32种成分,所鉴定的组分占总峰面积的93.42%;采用水蒸汽蒸馏法提取共鉴定出31种成分,所鉴定的组分占总峰面积的90.86%。超临界CO2萃取法和水蒸汽蒸馏法所提得的挥发油化学成分基本一致。超临界CO2萃取法比传统的水蒸汽蒸馏法具有提取快速、无需加热、能耗低、有效成分的萃取率较高等优点。

摘  要：
Essential oil in skin of Citrus suavissima was extracted by supercritical CO2 extraction and steam distillation,and isolated and identified by GC/MS analysis.Their chemical compositions and relative contents were determined by area normalization.Chromatographic conditions were: capillary column HP-5(30 m×0.25 mm,0.25 μm).The carrying gas was helium,the flow rate was 1mL/minute and the temperature was in rate of 5 ℃/minute from 60℃(hold 2 minutes) to 240℃(kept 30 minutes).Split injection with ratio of 50:1.Injection temperature of 280℃.32 and 31 volatile compounds were identified from chemical materials by supercritical CO2 extraction and by steam distillation,accounting for over 93.42% and 90.86% of total essential oil fraction.The results showed that supercritical CO2 extraction method had the advantages of faster extraction without heating,lower energy consumption,higher extraction efficiency than steam distillation.
