Objective To investigate the refining and concentration of the Banlangen aqueous extractives using membrane separation technology. Methods The membrane separation process for refining and concentration Banlangen aqueous extractives was optimized by the quality of products and membrane operation parameters, and was tested through medium-scale trials. Results The selected G2＋GM＋RO2 membrane process was suitable. The inherent quality of the products obtained by membrane separation process was better than that obtained by traditional process. Conclusion G2＋GM＋RO2 membrane process is suitable to refine and concentrate Banlangen aqueous extractives, and it has technical conditions for industrial scale trials.
