Abstract: The Content of the Diethylcarbamazine tablet was determined by ultraviolet spectrophotometry. The detecting wavelength was 211 nm, there was a good linear correlation in the range of 15～31μg/ml(r=0.9999).The average recovery was 100.42% with RSD of 0.61%(n=8). The results showed that the method was simple, stable and saving agents, there was no statistical difference between the results measured by the nonaqueous titration in Chinese Pharmacopea(1990)and by UV(P>0.05).
