| Abstract: | Coral ginger extract was obtained by supercritical C（）2 extraction technology under different conditions. Best ex- traction conditions were determined by orthogonal experiments, i.e. extraction time 15（I rain, extraction temperature 45＇C, C（）2 flow rate 20 l./h, extraction pressure 25 MPa. The composition of extract was analyzed by gas chromatography/mass spectrometry （GC/MS）, and 38 kinds of components were identified. The supercritical C02 extraction method is simple, rapid and efficient, does not destroy the thermal sensitive materials because of low operation temperature. The prepared coral ginger extract does not contain solvent residual. |
