摘要
阿斯匹林在碱性条件下可水解成水杨酸，在３３０ｎｍ波长处有最大吸收，用此原理测定抗感片中阿斯匹林的含量，实验结果表明，在１５～３０μｇ／ｍｌ范围内呈良好线性关系，回归方程Ｙ＝０．０１０２１＋０．０３８５５Ｘ，ｒ＝０．９９９５（ｎ＝６）。
In base medium,asprine can be hydrolysised to salicylic acid. The latter shows strong absorption at 300nm. Based on this principle, a method to determine the asprine content in 'Kanggan' tablet by UV spectrophotometry was established. The results showed that there existed good linear relationship at the range of 15￣30 μg/ml with regression equation Y=0.010+0.03855X(r=0.9995,n=6).
