高效液相色譜%鹽痠土黴素%有關物質
고효액상색보%염산토매소%유관물질
目的:建立HPLC测定盐酸土霉素有关物质和含量。方法:采用ODS柱(10 μm,4.6 mm×250 mm),以0.1 mo1.L-1草酸铵溶液-二甲基甲酰胺-0.2 mo1.L-1磷酸氢二铵溶液(60∶30∶10)(用氨试液调pH8.3)为流动相,检测波长270 nm。结果:盐酸土霉素在0.1~1.0 mg.ml-1浓度范围内,呈良好的线性关系(r=0.9999),精密度RSD为1.2%,平均回收率为99.6%,RSD为0.8%(n=4)。结论:该法简便、准确,适用于盐酸土霉素杂质的检测和含量的测定。
目的:建立HPLC測定鹽痠土黴素有關物質和含量。方法:採用ODS柱(10 μm,4.6 mm×250 mm),以0.1 mo1.L-1草痠銨溶液-二甲基甲酰胺-0.2 mo1.L-1燐痠氫二銨溶液(60∶30∶10)(用氨試液調pH8.3)為流動相,檢測波長270 nm。結果:鹽痠土黴素在0.1~1.0 mg.ml-1濃度範圍內,呈良好的線性關繫(r=0.9999),精密度RSD為1.2%,平均迴收率為99.6%,RSD為0.8%(n=4)。結論:該法簡便、準確,適用于鹽痠土黴素雜質的檢測和含量的測定。
목적:건립HPLC측정염산토매소유관물질화함량。방법:채용ODS주(10 μm,4.6 mm×250 mm),이0.1 mo1.L-1초산안용액-이갑기갑선알-0.2 mo1.L-1린산경이안용액(60∶30∶10)(용안시액조pH8.3)위류동상,검측파장270 nm。결과:염산토매소재0.1~1.0 mg.ml-1농도범위내,정량호적선성관계(r=0.9999),정밀도RSD위1.2%,평균회수솔위99.6%,RSD위0.8%(n=4)。결론:해법간편、준학,괄용우염산토매소잡질적검측화함량적측정。
OBJECTIVE:An HPLC method was established to determine oxytetracycline hydrochloride and related substances.METHODS:The liquid chromatographies equipped with 270 nm detector,μ Bondapak ODS column(4.6 mm×250 mm, 10 μm). The mobile phase is 0.1 mol*L-1 ammonium oxalate-dimethylformamide-0.2 mol*L-1 dibasic ammoniumphosphate(60 ∶30∶10)(adjusted with 3 mol*L-1 ammonium hydroxide to pH 8.3).RESULTS:The linearity is good (r=0.9999) in the range of 0.1~1.0 mg*ml-1.The recovery rate was 99.6%, RSD=0.8%.CONCLUSION:The method is simple,accurate and is very suitable for determination of oxytetracycline hydrochloride and related substances.
