6-Chloro-m-anisidine was obtained as one of the products by the acidic decomposition of elebopride and its main metabolites (total CP). This degraded product after derivatized with heptafluorobutyric anhydride was measured by use of mass fragmentography. A good calibration curve was obtained in the range 2-80 ng/ml of clebopride in rat blood. The concentration of total CP in rat blood after intravenous (0.1 and 0.5 mg/kg) and oral (0.5 mg/kg) administration was determined by this method.
6-Chloro-m-anisidine 是依波必利及其主要代谢物(总氯化石蜡)酸性分解的产物之一。这种降解产物经七氟丁酸酐衍生后,采用质量碎片法进行测定。在大鼠血液中氯波必利的浓度范围为 2-80 纳克/毫升时,获得了良好的校准曲线。大鼠静脉注射(0.1 和 0.5 毫克/千克)和口服(0.5 毫克/千克)后,其血液中总 CP 的浓度也是通过该方法测定的。
