%X An HPLC method with diazepam as internal standard was developed to determine nifedipine content and its uniformity in tablets. The analytical column was a C18 column, the mobile phase consisted of V (methanol):V(triethylamine, pH 5.20) = 68:32. The detection was carried out with UV detector (lambda = 237 nm). Under this condition, the linear range was wide(8-80 mg/L) and the recovery was high (99.86%). The proposed method is simple and accurate and the decomposed product can be separated as well. Therefore, the quality of nifedipine tablets can be effectively controlled.
