【Abstract】 Objective: To establish a HPLC method for the determ in ation of nifedipine in paster. Methods: The contents of drugs determined by HPLC on C 18 column using methanol-water(68:32) as mobile phase with UV detection a t 330 nm. Results: The method was linear over the range of 20~100 μg/ml (r =0.999 9). The mean recovery was 99.5% and RSD was 0.55% (n =9). Conclusion : The method was suitable for the determination of nifedipine in paster.更多还原
