摘  要:
为了建立兽用白头翁颗粒中白头翁皂苷B4的含量测定方法。利用HPLC法,采用HypersilC18柱(250mm×4.6mm,5μL),以乙腈-0.1%磷酸(27∶73,V/V)为流动相,检测波长为205nm,流速1.0mL/min,柱温30℃。以白头翁皂苷B4对照为参比,在白头翁颗粒色谱图中,对白头翁皂苷B4的保留时间及峰面积的RSD进行分析。采用外标法测定3批白头翁颗粒中白头翁皂苷B4的含量。试验结果显示,白头翁皂苷B4在0.1~2.0mg/mL范围内呈良好的线性关系,(r=0.9995,n=6),平均含量为11.29mg/g,平均回收率为99.28%(RDS=2.09%,n=9)。该方法操作简便、结果准确,重复性好,可用于兽用白头翁颗粒的质量控制。

摘  要:
To establish a method for determining the content of Pulchinenoside B4in veterinary Baitouweng granules,the HPLC method was adopted on the Hypersil C18(250mm×4.6mm,5μm)column.The mobile phase was consisted of acetonitrile-0.1%phosphoric acid(27:73,v/v)at the flow rate of 1.0 mL·min-1,column temperature of 30℃and detection wave-length of 205μm.The injection volume was 20μL.In the recorded chromatogram of the test preparation,Pulchinenoside B4 was used as a reference substance,and RSD(%)of the retention time and the peak areas were measured.Using the external standard method,the content of Pulchinenoside B4 was determined in the 3batches of preparation.The experimental results showed that the linear range of Pulchinenoside B4 was 0.1~2.0mg/mL with average content of 11.29mg/g,average recovery of 99.28%(RDS=2.09%,n=9).This method is simple and accurate with a good reproducibility and can be used for the quality control of veterinary Baitouweng granules.
