The present invention is based on the dissolution property measurement method of “Chinese Pharmacopoeia 2010 edition 2nd part appendix XC”. After dissolving the colloidal pectin bismuth-containing preparation in the dissolution medium, the proton acid dissociator is added to the eluate. Is added directly until 0.8 to 1.2 mol / L, the supernatant is centrifuged, and a color developing solution of citric acid or ascorbic acid and potassium iodide is added to cause color development. Disclosed is a method for detecting the dissolution property of a colloidal pectin bismuth-containing preparation, wherein the dissolution amount of the colloidal pectin bismuth is measured and calculated. The method for measuring the dissolution property of a colloidal pectin bismuth formulation disclosed in the present invention can effectively measure the dissolution curve and dissolution property of a colloidal pectin bismuth in a colloidal pectin bismuth-containing formulation, and satisfies the quality control requirements. [Selection] Figure 1本発明は、「中国薬局方２０１０年版二部付録ＸＣ」の溶出性測定法により、コロイドペクチンビスマス含有製剤を溶出媒体に溶解した後、溶出液にプロトン酸解離剤を溶出液中の水素イオン濃度が０．８～１．２ｍｏｌ／Ｌとなるまで直接添加し、上澄み液を遠心分離して、クエン酸又はアスコルビン酸とヨウ化カリウムの発色溶液を加えて発色させ、分光光度法によりビスマス換算によるコロイドペクチンビスマス溶出量を測定して計算する、コロイドペクチンビスマス含有製剤の溶出性の検出方法を開示する。本発明で開示するコロイドペクチンビスマス製剤溶出性の測定方法は、コロイドペクチンビスマス含有製剤におけるコロイドペクチンビスマスの溶出曲線と溶出性を効果的に測定でき、品質管理の要件を満たす。【選択図】図１
