摘要
目的建立HPLC法同时测定复方黄芪注射液中人参皂苷Re、Rg1的含量。方法采用HPLC法,色谱柱为Diamonsil TMCJ8柱(4.6mm×250mm,5μm),流动相为乙腈-50mmol·L^-1磷酸二氢钾缓冲溶液(体积比为20:80),柱温为25℃,检测波长为203nm,流速为1.0mL·min^-1。结果复方黄芪注射液中人参皂苷Re、Rg1与其他成分分离良好。人参皂苷Re的质量浓度在25~500mg·L^-1内(r=0.9998)、Rg1的质量浓度在25~300mg·L^-1(r=0.9998)内与峰面积线性关系良好,人参皂苷Re、Rg1的回收率分别为100.2%和99.8%,RSD分别为1.4%和2.0%。结论方法准确、重现性好,可用于复方黄芪注射液的质量控制。
Objective To determine the contents of the ginsenoside Re and Rgl in the compound Huangqi (traditional Chinese medicines) injection. Methods The DiamonsilTM C18 (4.6 mm × 250 ram, 5μm) column was used with a mobile phase of acetonitrile-50 mmol.L^-1 potassium dihydrogen phosphate buffer ( V : V = 20 : 80), the wavelength of the detector was set at 203 nm. Results The linear ranges of the ginsenoside Re and Rgl were 25 - 500 mg.L^- 1 ( r = 0. 999 8) and 25 - 300 mg. L^- 1 ( r = 0. 999 8) respectively. The average recoveries of the ginsenoside Re and Rgl were 100.2 % and 99.8 %, the RSDs were 1.4 % and 2.0 %, respectively. Conclusions The method is simple and accurate with a good reproducibility and can be used as a quality control method for compound Huangqi injection.
