| Abstract: | A method of extracting azadirachtin from Azadirachta indica with CO_2 supercritical fluid extraction was studied.The factors on pressure, temperature,CO_2 flow rate,solvent and ratios of solvent that have an effect on the yield were systematically studied.The results showed that the yield is highest under a suitable condition of CH_3OH as solvent and ratios of solvent 1∶3((g·mL~(-1))),extract pressure 32 MPa,extract temperature 32 ℃,CO_2 flow rate 10 kg·h~(-1),and the yield of azadirachtin was 0.220%. |
