采用联立方程组新解法不经提取分离直接测定面康净片中甲硝唑和维生素 B6的含量。甲硝唑和维生素 B6的平均回收率和相对标准偏差分别是 1 0 1 .4% ,0 .97%和1 0 0 .6% ,1 .31 %。方法简便、快速、准确
Adopting the new method of simultaneous equations to directly determine the content of metronidazole and vitamin B6 in noodles without extraction and separation. The average recoveries and relative standard deviations of metronidazole and vitamin B6 were respectively 1.04%, 0.97% and 1.06%, 1.31%. The method is simple, fast and accurate
