Abstract The content of cimitidine in Compound Cimitidine Capsules was determined by HPLC.The C18 column was used,with methanol6 mmol/Lsodiumhexanesulfonate solution(with phosphoric acid 0.3 mL)(240∶760) as the mobile phase and the detection wavelength at 218 nm. The standard curve for cimitidine was linear in the range of 8~40 μg/mL.Regression equation: Y=1.2396X-0.2516 ......
