摘要: |
以C18为固定相,0.1%磷酸溶液(用三乙胺调节pH值至3.5±0.1)—乙睛(70:30)为流动相,348 nm为检测波长,采用高效液相色谱法同时测定诺氟沙星、盐酸小檗碱预混剂中诺氟沙星和盐酸小檗碱的含量。诺氟沙星和盐酸小檗碱线性范围分别为0.5 μg~10 μg和0.1 μg~2 μg,平均加标回收率分别为103.3%和97.7%,RSD分别为0.77%和1.3%(n=5)。 |

Abstract: |
A HPLC method has been developed to determine the norfloxacin and berberine hydrochloride in norfloxacin and berberine hydrochloride premix, using C18 column with a mobile of 0.1 % phosphoric solution (adjusted pH value to 3.5±0.1 with triethylamine)-acetonitrile (70:30) and wavelength of 348 nm. The linear range of norfloxacin and berberine hydrochloride was 0.5 μg -10 μg and 0.1 μg-2 μg. The average recovery was 103.3% with RSD of 0.77% and 97.7% with RSD of 1.3 %(n=5). |
