应用化学动力学原理对白癜风丸进行了加速加温实验，选定补骨脂素含量为指标，考查本品的稳定性。结果表明，实验数据ｌｇＣ对时间呈线性关系，为一级反应过程，从斜率中求得反应速度，推算其有效期约为７年。
Accelerated heating experiment of Baifengfeng Pill was carried out using the principle of chemical kinetics. The content of psoralen was selected as the index and the stability of this product was examined. The results showed that the experimental data lgC showed a linear relationship with time, which was a first-order reaction process. The response rate was obtained from the slope, and the effective period was estimated to be about 7 years.
