Abstract: In this paper, 60% ethanol was used as solvent to extract flavonoids from Platycarya strobilacea Sieb.et Zucc., and the mass transfer kinetics of polyphenol at different temperature was investigated. According to Fick’s second law of diffusion, the kinetic equation for Platycarya strobilacea Sieb.et Zucc. extraction process was established with plate model, and the parameters, such as K(rate constant), Ea(activation energy), y(yield) were gained. The results could provide the valuable theory basis for the technical design and further research of total flavonoids extraction process.

Key words: Platycarya strobilacea Sieb.et Zucc., total flavonoids, extraction, dynamics
