Method for detecting dissolution rate of preparation containing colloidal bismuth pectin |
| abstract |
A method for detecting a dissolution rate of a preparation containing colloidal bismuth pectin includes steps of: according to “ Pharmacopoeia of the People's Republic of China , 2010 Edition, Volume 2, Appendix XC”, dispersing the preparation containing the colloidal bismuth pectin into dissolution medium, and directly obtaining dissolution liquid; adding a protonic acid dissociation agent into the dissolution liquid until a hydrogen ion concentration reaches 0.8-1.2 mol/L; centrifuging for separating a supernatant; coloring the supernatant by adding a chromogen solution of citric acid or ascorbic acid and potassium iodide to obtain a test solution; calculating a dissolution amount, which is accounted by bismuth, of the colloidal bismuth pectin with a spectrophotometry method. The method of the present invention well detects dissolution curves and rates of the colloidal bismuth pectin in the preparation thereof, satisfying quality control requirements. |
