摘要
目的:建立同时测定康复新液中尿苷和黄嘌呤含量的方法。方法:采用HPLC法,Diamonsil C18(250mm×4.6 mm,5μm)色谱柱,甲醇-水(5:95)作为流动相,于254 nm波长下检测,流速1.0 mL·min^(-1),柱温30℃。结果:尿苷、黄嘌呤分别在0.10~3.96μg·mL^(-1)(r^2=0.9998)、0.52~20.80μg·mL^(-1)(r^2=0.9992)浓度范围内线性关系良好,平均加样回收率分别为97.86%(RSD=1.25%)、97.39%(RSD=0.68%)。测定5批次康复新液中尿苷和黄嘌呤的含量范围分别为1.69~1.76μg·mL^(-1)、12.76~13.06μg·mL^(-1),说明各批样品质量较均一。结论:本文建立的方法精密度高、重复性好,操作简便快速,可用于康复新液的质量控制。
Objective: To establish a method to detect xanthine and uridine content in Kangfuxin Ye at the same time. Method: HPLC method was established. The separation was carried out on a Diamonsil C18 column (250 mm×4.6 mm, 5 μm) at 254 nm. The mobile phase was consist of MeOH and H20 (5:95) at the flow rate of 1 mL.min-1, and the column temperature was set at 30℃. Result: The linear ranges of uridine and xanthine were 0.10-3.96 μg. mL-1 (r2=0.9993) and 0.52-20.80μg. mL-1 (r2=0.9991), respectively. The average recoveries of uridine and xanthine were 97.86% (RSD=1.25%) and 97.39% (RSD=0.68%), respectively. The method was applied in the determination of 5 batches of Kangfuxin Ye. The content ranges of uridine and xanthine werel.69- 1.76 μg. mL-1 and 12.76- 13.06 μg. mL-1, respectively, which suggested that the quality of each batch was uniform. Conclusion: The method has high precision, good repeatability, simple and rapid operation. It can be used to control the standard of Kangfuxin Ye.
