Abstract: Oxalis
An optimum process is designed for extracting antibacterial active substance from
corymbosa ，
. The extraction time ethanol concentration and solid -liquid ratio are selected as
independent variables based on single factor experiment and the diameter of the inhibition zone is
，
considered as response value. After that a mathematical model is established to calculate and
verify the optimal extraction conditions and the theoretically maximum inhibition zone. The optimum
： ， ，
extraction process is shown as follows 73% ethanol concentration 78 min extraction time 1颐31
