采用高效液相色谱研究了抗肿瘤药物甲啶铂的水合反应，以及甲啶铂在0.9% NaCl溶液中的稳定性。结果表明，甲啶铂的水合反应遵循一级反应动力学规律，20℃时反应速率常数为k=0.03086 h-1，半衰期22.5 h，反应活化能E=80.6 kJ/mol；在0.9% NaCl溶液中，甲啶铂的水合反应被抑制，反应达到平衡后，甲啶铂的降解不超过4%。
HPLC analytical method was used to investigate the aquation of picoplatin, and the stability of picoplatin in 0.9% NaCl solution. The results show that the aquation of picoplatin followed the law of the first-order reaction, the rate constant was 0.03086 h-1, the half life period was 22.5 h, the activation energy was 80.6 kJ/mol. Picoplatin is stable in 0.9% NaCl solution, the degradation did not exceed 4% when the reaction achieved balance.
