Supercritical fluid extraction of essential oils is one of the most widely discussed applications inthe supercritical fluid literature. Peppermint leaf oil was isolated by a supercritical fluidextraction using CO2 in which the extraction was followed by a two-stage fractional separation.Chemical analysis revealed that oils extracted under different supercritical fluid extractionconditions possessed a widely different percentage composition. Oil obtained byhydrodistillation was also compared with the extracted oils. Although practically the samecompounds were present in the hydrodistilled oil, its composition was similar to supercriticalfluid extraction oil extracted under non-optimised conditions. The oil obtained at optimumsupercritical fluid extraction conditions (p = 90 bar, T = 40 C) had a fragrance that betterresembled that of the peppermint leaves used for the extraction of the oils. |
