Objectives:To get Levodopa, extracting from Mucuna, purifying and concentrating by using the new membrane separation technology. Methods:The leaching mention levodopa when each affecting factor was studied, by establishing orthogonal experiment, through analysis of experimental results after optimization, determines the final leaching mention parameters. To the M pruriens Var.utilis Burck leaching carry liquid separation membrane purification process of removing impurity and membrane enrichment technology systematically studied through the experiment method and result analysis, discusses the different separation membrane to levodopa extract removing impurity, concentrated effect, and finally determined that the triple membrane process. Results:Levodopa product yield from the traditional craft 50%to 68.65%, while the purity of refined products reached 99.53%. Conclusion:Using a new type of membrane separation technology is feasible for separating and purificating of levodopa. And membrane process is low energy consumption, less pollution, without the use of toxic reagents, to achieve a cleaner production.
