摘要
Abstract
A high performance liquid chromatography method was established for quantitative determination of disodium 5′-inosinate and disodium 5′-guanylate(IMP and GMP).Using tetrabutylammonium phosphate monobasic and potassim dihydrogen phosphate mixed with a certain proportion of acetonitrile as the mobile phase,the standard samples were analyzed on Waters RP 18 column under the optimal conditions.The qualitative and quantitative reproducibility of RSD were below 2%.On the IMP standard curve,the linear range was 60~600 μg/mL,the correlation coefficient R being 1.000.On the GMP standard curve,the linear range was 50~480 μg/mL,the correlation coefficient R being 0.999 9.The method was used to determine IMP and GMP content in a certain brand of chicken extract,which was 0.54% and 0.60%,respectively,the precision being 0.73% for GMP,1.17% for IMP.关键词
