摘要
研究以高效液相色谱法控制澳洲茄胺盐酸盐质量的方法。色谱柱为Agilent ZORBAX Eclipse XDB-C18柱(150mm×4.6mm,5μm),流动相为V甲醇:V乙腈:V0.020mol·L^-1乙酸铵=60:35:5,流速为1mL/min,检测波长为205nm,进样量为10μL。结果表明,采用该方法澳洲茄胺盐酸盐与其他杂质分离良好,线性范围5-500μg/mL(r=0.9993,理论塔板数n〉12000,R〉1.5),加样平均回收率为98.6%(n=9),重现性试验相对标准偏差(RSD)为0.618%。
High-perfomance liquid chromatography was used to study how to control solasedine quality. Column was Agilent ZORBAX Eclipse XDB-C18 column (150mm×4.6mm,5μm) hydrochloride mobile phase was Vmethanol: Vacetonitrile:V0.020mol·L^-1 tate = 60 : 35 : 5, flow rate was 1mL/min, detection wavelength 205 nm, injection volume 10 IxL, the solasodine hydrochloride quality separated from other impurities in a good linear range of 5-500μg/mL (r =0.9993), numder of theoretical plates n 〉 12 000(R 〉 1.5) ; the average recovery for the sample 98.6% ( n = 9). Relative standard deviation of reproducibility (RSD) was 0.618%.
