| Abstract: | By the designation of mono-factor experiments and orthogonal multifactor experiments, influences of extraction temperature, extraction pressure, CO2 flow rate and extraction times on the yield of oil from the leaves of Vitex negundo L. var. heterophylla (Franch.) Rehd. in the supercritical CO2 extraction process were investigated. The obtained optimal extraction technology was: the extraction pressure: 22 MPa; the extraction temperature: 45 degrees C; the CO2 flow rate: 25 L/h and the extraction time: 3h. The oil yield on the above supercritical CO2 extraction conditions was 3.22%. |
