The parameters of one-component kinetic model (OKM) and two-component kinetic model (TKM) for extracting flavonoids from scutellaria radix were calculated when the kinetic curves at 4 different temperatures were obtained under 50% ethanol as solvent, liquor-to-solid ratio of 20g/mL and scutellaria radix particles with the size of 20～40 mesh as the experimental material. It indicates that both of the regression results of the two models fit the experimental data well with the correlation coefficient of regression (R2) more than 0.9800 and the relative standard deviation of regression (RSD) less than 1.00%. And although the regression result of TKM was better than that of OKM, the changing of some TKM parameters with temperature were unreasonable.
