Abstract: | Objective To establish a method of determining the content of raceanisodamine and prazosin hydrochloride in prazosin hydrochloride raceanisodamine tablets.Methods HPLC Fortis C18 analytical column(250 mm × 4.6 mm,5 μm) was used and the mobile phase was methanol-a mixture solution of 3.484 g·L-1sodium pentanesulfonate solution and 3.64 g·L-1tetramethyl ammonium hydroxide solution with p H adjusted to 5 by acetic acid(45∶ 55).The flow rate was 1.0 ml·min-1and the detection wavelength was 225 nm.Results For raceanisodamine,the regression equation was Y = 3639 X-172.87,r = 0.9998(n = 6),the linearity ranged from 5.625 to 225 μg·ml-1,the average recovery was 99.86% and RSD was 0.95%.For prazosin hydrochloride,the regression equation was Y = 27 637 X + 8100.8,r = 0.9999(n = 6),the linearity was between 1.9925 and 79.7 μg·ml-1,the average recovery was 100.41% and RSD was 1.15%.Conclusion This HPLC method is accurate,quick and simple for determining the content of the compound. |
