摘要
采用反相高效液相色谱法(RP-HPLC),以Kromasil C18柱(250×4.6mm,5μm)为色谱柱,甲醇-0.05M磷酸二氢钾(25:75)为流动相,在254nm检测波长,1.0ml/min流速的条件下建立中风康复片中士的宁的含量测定方法。结果表明,中风康复片中士的宁与其它成分分离良好,士的宁在0.072~0.648μg范围内呈良好的线性关系(r=0.9999),测量方法的平均回收率为95.51%,RSD=0.7%(n=6)。该方法灵敏度高、操作简单、结果准确,可用于本制剂的质量控制。
To establish a RP-HPLC method for determination of strychnine in Zhongfeng Kangfu Tablet. The sample were analyzed by RP-HPLC using Kromasil (250×4.6mm, 5μm) column; methanol -0.05M potassium dihydrogen phosphate (25 : 75) as mobile phase;UV detector at 245nm and the flow rate was at 1.0ml/min. The result was the content of strychnine had a good linearity in the range of 0. 072~0. 648(μg),the correlation was 0. 9999,the Average recovery was 95.51%, RSD = 0. 7% (n =6). The method was sensitive, simple, accurate and suitable for quality control of strychnine in Zhongfeng Kangfu tablet.
