目的 建立高效液相色谱法测定肾肺康口服液方法。方法 色谱柱为十八烷基硅烷键合硅胶柱 ,4 .6mm× 2 5 0mm :流动相 :磷酸盐缓冲液 (pH 6 .5 ) [取 0 .0 1mo1/L磷酸二氢钠 6 8.5mL与 0 .0 1mol/L磷酸氢二钠 31,5mL ,混合 (pH 6 .5 ) ] 甲醇 (17∶3)流速 :0 .7mL/min ;检测波长 :2 6 0nm ,外标定量。结果 腺苷平均加样回收率为 10 0 .0 % ,RSD =1.5 %。结论 方法简便、准确 ,适用于该产品质量检验分析。
Objective To establish a method for determination of Shenfeikang oral liquid by high performance liquid chromatography. Method The chromatographic column was octadecylsilane-bonded silica gel column, 4.6mm × 250mm: mobile phase: phosphate buffer (pH6.5) [taken from 0. 0 1mo1/L sodium dihydrogen phosphate 6 8.5mL With 0. 0 1mol/L disodium hydrogen phosphate 31,5mL, mixed (pH 6.5) ] methanol (17:3) flow rate: 0.7mL/min; detection wavelength: 260nm, external standard quantitative. Results The average recovery of adenosine was 10 0.0%, RSD = 1.5%. Conclusion The method is simple and accurate, suitable for the product quality inspection analysis.
