反相高效液相色谱法测定盐酸奈法唑酮片的含量
RP-HPLC determination of nefazodone hydrochloride tablets
【摘要】 目的:建立高效液相色谱法测定盐酸奈法唑酮片的含量。方法:采用 Hypersil ODS2 C18柱(250mm×4.6mm,5μm),以甲醇-0.025mol·L-1醋酸铵(含0.2%三乙胺)溶液(75:25)为流动相,流速1.0mL·min-1,检测波长250nm。结果:含量测定的线性范围在50~1000μg·mL-1之间,r=0.9999(n=7)线性关系良好,平均回收率为99.7%,RSD 为1.5%。结论:本方法准确、简便、快速,重复性好。
【Abstract】 Objective:To establish an HPLC method for determination of nefazodone in tablets.Methods:Chroma- tographic conditions:Hypersil ODS2 C18 column (250 mm×4.6 mm,5μm),as stationary phase;mobile phase was methanol-0.025 mol·L-1 ammonium acetate (contain 0.2% triethylaminer) solution (75:25);the flow rate was 1.0 mL·min-1,detection wavelength was set at 250 nm.Results:The linear range was from 50 μg·mL-1 to 1000 μg·mL-1;r=0.9999 (n=7).The average recovery was 99.7% and RSD of 1.5%.Conclusion:The method is simple,sensitive,accurate.
