摘要
以甲醇-水-乙酸(75∶20∶5)为流动相,在SpherisorbC18柱上,以对乙酰氨基酚为内标,用电化学检测器测定复方利血平片中利血平含量。其平均回收率为99.01%,RSD为1.51%。
Reserpine can be determined on a Spherisorb C18 column with a mobile phase of methanolwateracetic acid(75∶20∶5) and flow rate of 1.50 ml/min,column temperature was 40°C and operating potential for electrochemical detector was 0.70 V.Paracetamol was internal standard.The linear range was 0.1~10.0 μg/ml,and the detection limit 0.1 μg/ml.The average recovery was 99.01% with RSD of 1.51%.
