Breeding a high pyrimidine producting grain is the precondition for producting cytidine and uridine by fermentation.
选育嘧啶核苷高产菌是实现发酵法生产胞苷、尿苷的前提.
Methods: Adenosine, Uridine and Guannosine were determined by TLC - Scanning samples were performed by fluorescence quenching analyis.
方法: 采用高效薄层色谱扫描法进行含量测定, 同时建立了不同虫草样品的荧光淬灭薄层色谱指纹图谱.
