[Study of supercritical-CO2 fluid extraction in extracting essential oils of Amomun tsao-ko].
Essential oils from Amomum tsao-ko are extracted by supercritical-CO2 fluid and the oils are analyzed by GC-MS. 1, 8-cineole, trans-geraniol eicosatrienoic acid methylester and d-nerolidol of them are the major constitutents, 12 constitutents of them are first obtained from the plant.
