| 中文摘要:目的 建立用比色法与分光光度法测定静肤平中红霉素、甲硝唑含量的方法 。方法 以稀盐酸(9→1000)溶液为溶剂,在417nm,277nm波长处进行测定。结果 红霉素在5.0～20.0μg/ml浓度范围内线性关系良好。红霉素的平均回收率为98.55%,RCD为0.52%(n=5),甲硝唑的平均回收率为98.86%,RCD为0.51%(n=5).结论 本方法简便快捷、准确,制剂中的其他成分不干扰测定。 |

| Abstract:OBJECTIVE To estabish a quantiative analysis for Jing fu ping liqour.METHODS Jing fu ping liquor was determined in 0.1mol/L HCl.The wavelength of detection were 417nm and 277nm.RESULTS There were good linear correlation in the range of erythromycin(5.0～20.0μg/ml) and metronidazolum(2.0～15.0μg/ml),the average recovery and relative standard deviation were 98.55% and 0.52%(n=5) for erythromycin 98.86% and 0.51%(n=5) for metronidazolum.CONCLUSIONS The method is simple,rapid and auurate. |
