【 摘 要 】

A kinetic model of flavonoid from spina gleditsiae by supercritical CO2 fluid extraction was developed by an adsorption-desorption equilibrium model. Extraction kinetic curves were fitted by origin mathematical software, and then used for prediction and experimental verification. The results showed that the prediction were consistent with the experimental process. This model illustrates solution-mass transfer mechanism of flavonoid from spina gleditsiae in supercritical extraction process, and has the advantage not only for better precision it offers, but also for the fact that it only requires moderate experimental conditions.
