感冒通片中的主药成分为双氯芬酸，人工牛黄，根据江苏省药品标准（８７）年采用比色法测定人工牛黄的含量，但在实际操作中，往往测得的含量值不稳定，本文通过多次实验，认为控制显色剂的质量，控制显色反应的温度和时间是获得较满意结果的关键，我们的具体作法如下。１　实 The main ingredient of the drug in the common cold is diclofenac and artificial bezoar, and the content of artificial bezoar is determined by the colorimetric method according to the standard of Jiangsu Province (87) years. However, in practice, the content is often not stable, Many experiments, that the control of the quality of the developer, the color temperature control and timing of the reaction is the key to obtaining more satisfactory results, our specific practices are as follows. 1 real
