摘　　要：目的:建立胃舒散中主药碱式碳酸铋的化学反应鉴别方法。方法:将供试品进行有机炽灼破坏后,再根据《中国药典》碱式碳酸铋的碘化钾鉴别方法,选用稀硝酸为溶剂对铋盐进行定性分析。结果:供试品硝酸滤液均呈铋盐正反应,且可明显消除胃舒散中中药组分对碱式碳酸铋鉴别的干扰及假性反应,颜色鉴别直观。结论:本方法简便、稳定,可用于该制剂的质量控制。OBJECTIVE:To establish the chemical identification method of bis muth subcarbonte in weishusan.METHˉODS:The samples were ignited,then bismuth subcarbonate in residue was identified by the identification method of bismuth of identification method of potassium iodide from Chinese Pharmacopenia,with dilute nitric acid as solvent.RESULTS:Bisˉmuthic salt positive result was found in all dilute nitric acid solvent,this method could eliminate the interference with identiˉfication of bismuth subcarbonate from traditional Chinese medicinal components in weishusan,it could also exclude the pseuˉdo-positive and pseudo-negative reaction,the color was easy to identify.CONCLUSION:This method is simple and stable and therefore applicable to quality control of weishusan.
