This article optimized supercritical fluid extraction process conditions of paeoniflorin by using response surface methodolog at first, and then established the mathematical model of supercritical fluid extraction, finally summarized mass transfer process of supercritical CO_2 extraction containing entrainer.
On the basis of one-factor tests and the Box-Behnken center-united experimental design principle, the method of response surface analysis with 3 factors and 3 levels was adopted. A second...
