| Abstract: | This paper developed a HPLC method for the determination of bepridil in plasma. Using YWG-C18 column (10um, 15cm X 4.6mm I. D. ), the separation was performed at detecting wavelength 254nm. The mobile phase consisted of methanol: water:10% TEA-phosphoric acid(pH4. 5): dichloromethane = 75 : 15 : 10: 5 (V/V) at the flow rate of 1.0ml/min. 1.0ml plasma sample was extracted with 4.0ml n-hexane: iso-butylalcohol (98 : 2). Apridine was used as internal standard. The linear concentration range was 10-2 000 ng/ml and the minimum detectable limit was 3ng/ml. The average extraction recovery was 90. 02% and recovery was 100. 23%. The intra-day RSD was <4% and inter-day RSD was |
