| 摘 要： | 目的 建立一种快速、准确、高灵敏度的检测含巯基药物的化学发光分析方法.方法 在硫酸酸性介质条件下,高锰酸钾可与乙二醛产生化学发光,而含巯基药物对该化学发光有显著的增强作用,基于此现象建立了流动注射化学发光分析法测定含巯基药物的新方法.结果 实验对影响化学发光的可能因素和参数进行了优化,在优化的条件下,甲巯咪唑、卡托普利和乙酰半胱氨酸分别在1.0×10~(-8)～5.0×10~(-6)、7.0×10~(-8)～1.0×10~(-6)和3.0×10~(-8)～1.0×10~(-6)g/mL浓度范围内与相对化学发光强度成良好的线性关系,检测限分别为1.0、3.9、3.7ng/mL.结论 本方法已成功应用于3种含巯基药物制剂的含量测定,与药典方法比较,结果满意.

| Abstract: | Objective To establish a rapid,accurate and sensitive chemiluminescence method for determining sulfydryl-containing drugs.Methods In sulfuric acid solution,glyoxal could be oxidized by potassium permanganate,and weak chemiluminescence could be observed.Chemiluminescence signal could be enhanced in the presence of sulfydryl-containing drugs.Thus,on this basis we established a new method of determining the concentration of sulfydryl-containing drugs with flow injection chemiluminescence analysis.Results Under... |
