目的:建立土霉素片的含量测定方法。方法高效液相色谱法。采用Luna-C18色谱柱,以0.05 mol/L草酸铵溶液-二甲基甲酰胺-0.2 mol/L磷酸氢二铵(70∶25∶5)为流动相,用紫外检测器在282 nm波长处检测。结果土霉素片浓度在0.01~1 mg/mL范围内与峰面积线性关系良好(r=0.9990),平均回收率为100.1%。结论高效液相色谱法快速、简便、准确,可用于土霉素片的含量测定。
目的:建立土黴素片的含量測定方法。方法高效液相色譜法。採用Luna-C18色譜柱,以0.05 mol/L草痠銨溶液-二甲基甲酰胺-0.2 mol/L燐痠氫二銨(70∶25∶5)為流動相,用紫外檢測器在282 nm波長處檢測。結果土黴素片濃度在0.01~1 mg/mL範圍內與峰麵積線性關繫良好(r=0.9990),平均迴收率為100.1%。結論高效液相色譜法快速、簡便、準確,可用于土黴素片的含量測定。
목적:건립토매소편적함량측정방법。방법고효액상색보법。채용Luna-C18색보주,이0.05 mol/L초산안용액-이갑기갑선알-0.2 mol/L린산경이안(70∶25∶5)위류동상,용자외검측기재282 nm파장처검측。결과토매소편농도재0.01~1 mg/mL범위내여봉면적선성관계량호(r=0.9990),평균회수솔위100.1%。결론고효액상색보법쾌속、간편、준학,가용우토매소편적함량측정。
Objective To establish a method for determination of the content of Oxytetracycline tablets. Methods High performance liquid chromatography. The WH-C18 column, with 0.05 mol/L ammonium oxalate solution-two methyl formamide-0.2 mol/L diammonium hydrogen phosphate (70∶25∶5)as mobile phase, using a UV detector at 282 nm wavelength. Results Oxytetracycline Tablets concentration relationship in 0.01-1 mg/mL scope with the peak area of linear(r=0.9990), the average recovery rate was 100.1%. Conclusion The HPLC method is rapid, simple and accurate, can be used for the content determination of Oxytetracycline tablets.
