摘要
根据化学动力学原理,采用恒温加速试验方法对阿魏酸水溶液的化学稳定性进行了研究,通过高效液相色谱法测定样品中阿魏酸含量。结果表明,阿魏酸在水溶液中的分解符合一级反应,以经典法和简易法计算,预测得到室温下(25℃)阿魏酸在水溶液分解10％时间(即药物有效期)为1.59a和1.43～1.70a。
The chemical stability of aqueous solution of ferulic acid was studied by the constant temperature accelerated test according to the princiPle of chemical dynamics. The ferulic acid in sample was determined by HPLC. The result showed that the decomposition of ferulic acid in aqueous solution accords with the primary reaction. At room temperature (25℃),the time of decomposition of 10℃ ferulic acid in aqueous solution (the expiry date of drug) was calculated robe 19. 36mo and 17.41 too-20. 69mo,calculated by classical and simple calculation methods, respectively.
