介绍了应用高效毛细管电泳技术测定肌苷口服液含量的方法。实验是将肌苷口服液直接进样，以硼酸－硼酸盐为缓冲溶液。实验的回收率为９５．０％～９９．８％，相关系数０．９９８５，精密度的变异系数小于５％。方法简便、快速、准确、灵敏度高 The method of determining the content of inosine oral liquid by high performance capillary electrophoresis was introduced. The experiment is inosine oral solution directly injected to boric acid - borate buffer solution. The experimental recoveries ranged from 95.0% to 99.8% with a correlation coefficient of 0.9985. The coefficient of variation of precision was less than 5%. Method is simple, fast, accurate, high sensitivity
