摘要
目的建立胆酸-HP-β-CD包合物中胆酸的含量测定方法,为胆酸-HP—β—CD包合物的制备工艺参数优化试验提供含量测定方法。方法采用高效液相色谱法:Welchrom-C18色谱柱(5μm,4.6×250mm;流动相为乙腈-水-磷酸(60:40:0.06);流速1.0mL·min^-1;柱温40℃;检测波长192nm。结果胆酸在0.0625-1g·mL。范围内线性关系良好(r=0.999);平均回收率为99.33%,RSD为0.66%。结论该方法简便,准确,重复性好,适宜作为胆酸-HP-β-CD包含物中胆酸的含量测定方法。
OBJECTIVE Set up CA's assaying method to offer assaying method for optimizing technology parameter of CA-- HP--β-- CD preparation. METHODS HPLC.. Chromatographic column: Welchrom-- C18 (5μm, 4. 6 × 250mm) ; Mobile phase : acetonitrile-- water-- phosphoric acid(60 : 40 : 0. 06) ; Flow rate: 1.0mL · min^- 1 ; Column temperature: 40℃ ; Detector wavelength:192nm. RESULTS Linear relationship is fine from 0. 0625-1mg · mL^-l( r = 0. 999); Average recovery was reproduoducibility. It s fit 99. 33%, RSD =0.66%. CONCLUSION The method is convenient and accurate. It also has fine reproducibility.It' so as CA's assaying method.
