It has been recorded in the Chinese Pharmacopeia (1990) and many other countries’ pharmacopeias. In recent years, the Chinese scholars have found out that mnifedipine has a stronger and more lasting effect on the cardiovascular than nifedipine, but its inhibitory effect on myocardium is weaker. For further study on nifedipine, we intend to search for a highly selective and simple analytical method. The analysis展开更多
