摘要: 目的:建立高效液相色谱(high efficiency liquid chromatography,HPLC)法测定交沙霉素原料药中主组分的含量。方法采用十八烷基键合硅胶柱(C18)为固定相,以高氯酸溶液(取高氯酸钠-水合物119g,加水至1000 mL,用1mol/L的盐酸调节 pH 值为2.5)-乙腈(60∶40)为流动相。柱温为40℃,检测波长为231nm,进样量为20μL。结果交沙霉素主组分在考察的浓度范围内线性关系良好,线性范围为0.1255~0.8785g/L(r =1.0000),平均回收率为99.7%。定量限为2.51ng,最低检出限为0.84ng。结论 HPLC 可用于交沙霉素原料药中主组分含量的测定,快速简便,准确可靠,灵敏度高。

Abstract: Objective A high efficiency liquid chromatography method was established for the determination of principal component crude drug josamycin.Methods A octadecyl bonded silica column was used as the stationary phase,with the mobile phase of mixture of perchloric acid solution-acetonitrile (60∶40)at the detection wavelength of 231nm.The column temperature was 40℃ and the injection volume was 20μL.Results The principal component of josamycin showed a linear range within 0.125 5- 0.878 5g/L (r = 1.000 0).The average recovery was 99.7%.The quantitation and detection limits were 2.51ng and 0.84ng,respectively.Conclusion The method was rapid,simple,accurate,sensitive,and suitable for the determination of principal component in crude drug josamycin.
