摘要:

以生晒参为原料,响应面分析法优化超临界CO2提取挥发油的工艺。采用自动质谱退卷积定性系统和保留指数方法对挥发油化学成分定性。结果表明:最佳工艺条件为萃取压力38 MPa、萃取温度55 ℃、静态萃取时间2 h、动态萃取时间1 h,此条件下挥发油提取率达1.12%。气相色谱-质谱法结果显示分离出35 个色谱峰,鉴定出29 种化学成分,相对含量占挥发性物质的96.69%。

Abstract:

The supercritical-CO2 fluid extraction conditions of volatile oil from dried raw ginseng were optimized by
response surface methodology. Chemical constituents of the essential oil were analyzed by gas chromatography-mass
spectrometry (GC-MS) combined with automated mass spectral deconvolution and identification system (AMDIS) based
on retention index. The optimal extraction conditions were determined as follows: extraction pressure, 38 MPa; extraction
temperature, 55 ℃; static extraction time, 2 h and dynamic extraction, 1 h, under which, the maximum oil yield of 1.12%
was obtained. A total of 35 chromatographic peaks were separated from the essential oil of ginseng roots, 29 of which were
identified, accounting for 96.69% of the total peak area.

Key words: ginseng essential oil, supercritical fluid extraction, response surface methodology, automated mass spectral deconvolution and identification system (AMDIS), retention index
