摘要
目的:制备马蔺子素冻干注射剂并对其稳定性进行考察。方法:应用化学动力学原理考察马蔺子素降解规律和影响因素,并采用经典恒温法考察马蔺子素冻干注射剂的稳定性。结果:马蔺子素具有较高的油水分配系数,且水溶液易受pH催化降解,对热不稳定,马蔺子素-羟丙基-β-环糊精包合物冻干注射剂可明显提高其稳定性。结论:马蔺子素包合物冻干注射剂具有良好的稳定性。
AIM： To prepare the irisquinone freeze-drying injection and investigate its stability. METHODS： The degradation pattern of irisquinone and its effects were measured. At the same time, the stability of freezedrying injection by classic thermostatical test. RESULTS： Irisquinone solution was unstable to heat and its content decreased remarkably in acid and alkaline solutions. The result showed that oil/water partition coeffecient of irisquinone was very large. The irisquinone-hydropropyll-β-cyclodextrin inclusion complex freeze-drying injection was very effective to enhance the drug stability. CONCLUSION： Irisquinone inclusion complex injection has character of good stability.
