【Abstract】 Objective: To determine stability of cisplatin in water or sodium chloride solution, a HPLC method was estab-lished for the determination of degradation products of cisplatin in both solutions. Methods: The chrornatographic conditions were NH2 column; 0.5 % sodium chloride solution was used as mobile phase; detection wavelength was at 210nm. Results: The standard curve was linear in the concentration range from 0. 50 to 1.5 mg·ml-1 ( r-0. 999 7). The RSD of cisplatin peak area was 0.75 %(n =6). Conclusion: The degradation products in cisplatin solations were quantitatively determined by HPLC method. The light could accelerate degradation reaction of cisplatin in sodium chloride solution.更多还原
