The steady-state flow method was used for supercritical CO2 extraction study on tea polyphenols aqueous solution . Solubility data were determined for tea polyphenol in the mixture of CO2-H2O-tea polyphenol. Peng-Robinson Equation of State were calculated the solubility of tea polyphenol in supercritical CO2 in the SVE system of literature, the interaction parameter k13 were estimated. Combination of the tea polyphenols aqueous solution at 40℃ in supercritical CO2 solubility data obtained k23 Phase equilibrium data of tea polyphenols aqueous solution in the supercritical CO2 was predicted. The calculated solubility data of tea polyphenol aqueous solution in supercritical CO2 in the VLE system were compared with the experimental data. Based on the Peng-Robinson Equation models, the calculated solubility are in good agreement with the experimental data.
