| Abstract: | To determine the method for extracting the essential oil from Gardenia jasminoides and optimize the technique parameters. Supercritical CO2 extraction was used and extraction ratio was taken as the index in orthogonal test to analyze some action factors,such as extraction temperature and pressure,separation temperature and pressure. The influence of extracted pressure,separated temperature and separated pressure on extraction ratio was significant,while the extracted temperature was not significant. The bes... |
