Aiming at above problem, this paper put forward the strategy of separation as follows. Firstly, in view of great amount of coloring matter in solution, the quality of product is declined. So we decolor the solution by acticarbon, which makes 80% coloring matter be removed, but the loss of nucleotides is only about 2%. Secondly, on the basis of physical and chemical properties of four nucleotides, we first synthesized a kind of cation exchange resin by ourselves which is used to separate four matters preliminarily.

针对以上问题，本文提出了如下的分离策略：首先，由于酶解液中色素含量较多，使经树脂分离所得UMP和GMP中色素残留较多，最终导致成品质量的下降，所以我们用活性炭对酶解液进行脱色处理，使溶液中80％以上的色素被吸附除去，而核苷酸的吸附损失仅为2％左右。
