| Abstract_FL | Objective To optimize the technology of separating and purifying tea saponin from tea seed cake by macroporous adsorption resin, and provide the basis for further developing tea seed resources. Methods With the adsorption rate and analytic rate of tea saponin as the indexes, the optimal resin was selected by static adsorption and analytical experiment. The parameters of the optimal resin dynamic adsorption and desorption tea saponin were optimized by single factor experiment, orthogonal experiment and confirmatory experiment. Results The static adsorption capacity and desorption rate of D101 resin were 142.974 mg/g and 98.02%, respectively, which was the optimal resin for the separation and purification of tea saponin. When the yield of tea saponin was the main factor, the optimal dynamic adsorption and desorption process parameters for the sample mass concentration was 10 mg/mL, the sample flow rate was 3 BV/h, the sample volume was 6 BV, ethanol elution volume concentration was 80%, elution flow rate was 3 BV/h, eluent volume was 5 BV. Under the conditions of the process parameters, the yield of tea saponin was 74.25% and the purity was 84.30%. When the purity of tea saponin was the main consideration, the optimal parameters of dynamic adsorption and desorption for the loading mass concentration was 10 mg/mL, flow rate was 4 BV/h, sample volume was 7 BV, ethanol elution volume concentration was 70%, elution flow rate was 3 BV/h, elution volume was 5 BV, under the conditions of the process parameters, tea saponin purity was 97.7%, the yield was 72.04%. Conclusion D101 macroporous resin is a good resin which can be applied to the separation and purification of tea saponin in tea seed cake. |
