摘要
目的建立以高效液相色谱法测定虎黄烧伤搽剂中虎杖苷含量的方法。方法采用高效液相色谱法,以虎杖苷为对照品,色谱柱为ZORBAX Eclipse Plus C 18 (250mm×4.6mm,5μm),流动相为乙腈-水(23∶ 77),流速为1.0mL·min^-1 ,柱温为35℃,检测波长为306nm。结果虎杖苷的线性范围为0.10368~0.24192μg(R=0.9998),平均回收率为100.6%(N=6),3批样品含量测定结果均值为:本品每1mL含虎杖苷为0.72mg。结论本方法专属性强,重现性好,且稳定,可靠。
OBJECTIVE To establish the method of determination the content of Polydatin in HuHuang burn liniment by HPLC. METHODS HPLC methods was used and Polydatin was selected as reference substance.The ZORBAX Eclipse plus C 18 column (250mm×4.6mm,5μm) was used.The mobile phase was Acetonitrile-water (23∶ 77),with a flow rate at 1.0mL·min -1 and the column temperature was maintained at 35℃ and wavelength at 306nm. RESULTS The linear range for detection of polydatin was 0.10368~0.24192μg (R=0.9998).The average recovery rate of the method was 100.6%(N=6).The average content of the three batches of samples was 0.72mg per 1mL of polydatin. CONCLUSION The method was reliable and stable with good reproducibility and strong specificity.
