[Studies on the supercritical-CO2 fluid extraction and quality evaluation of ginger oils].
Essential oils from the dried rhizomes of Zingiber officinale were extracted by supercritical-CO2 fluid(SFE-CO2) and traditional water still distillation (WSD) methods, and the SFE extraction technology and quality (GC-MS, etc.) of the oils were studied. The results showed that the SFE-CO2 contains 49 constituents, such as 6-paradol, etc, the ginger peppery component of them gets to 22.90%.
