Abstract:
AIM: To explore the kinetics and thermodynamics parameters in the extraction of flavonoids from Fagopyrum tartarjcum . METHODS: Rutin was adopted as marker substance to create a regression equation between Rutin concentration and absorbance by meaus of UV. RESULTS: According to Fick diffusion principle Ⅱ, extraction process was analysed to gain parameters, such as K, Ea, Y, t 1/2 , K ?. CONCLUSION: The method would be useful for the process design and the choice of operation condition to extract flavonoids from Fagopyrum tartarjcum.
