| Abstract: | A new method for the determination of the content of tolterodine-L-tartrate was developed by UV spectrophotometry with methanol as solvent at 283nm.The absorbance is proportional to the concentration in the range of 2.208×10~(-5)-4.289×10~(-4)mol/L,and the recovery in real sample was 97.7%.This method is well reproducible,accurate,simple and reliable.It is applicable to determine the content of the tablet of tolterodine-L-tartrate with satisfactory results. |
