A high-performance liquid chromatographic method for the determination of amphotericin B concentrations in human serum without bilirubin interference was developed and compared with a microbiological assay. The high-performance liquid chromatographic assay utilized a reversed-phase trimethyl silica column, simple sample preparation, and visible detection. Reproducibility studies yielded coefficient-of-variation ranges from 1.02 to 2.11% for within-day precision and 2.88 to 4.32% for between-day precision. The correlation coefficient with the microbiological assay was 0.984 for amphotericin B.
建立了一种用于测定人血清中两性霉素B浓度且无胆红素干扰的高效液相色谱法,并与微生物测定法进行了比较。高效液相色谱测定法采用反相三甲硅烷基硅胶柱、简单的样品制备方法和可见光检测。重现性研究得出日内精密度的变异系数范围为1.02%至2.11%,日间精密度的变异系数范围为2.88%至4.32%。两性霉素B与微生物测定法的相关系数为0.984。
