目的:建立胃镜润滑胶浆中非法掺入化学药品盐酸利多卡因的检测方法。方法:对胃镜润滑胶浆提取后采用高效液相色谱-二极管阵列检测法。结果:供试品胃镜润滑胶浆中检测到与盐酸利多卡因对照品的色谱图和紫外扫描图一致的峰。结论:该方法专属性强、灵敏度高、操作简便,可作为分析检测非法添加盐酸利多卡因的有效方法。
Objective: To establish a method for the detection of lidocaine hydrochloride illegally mixed with chemical drugs in gastroscopic lubricating paste. Methods: Gastroscope lubricating paste was extracted by high performance liquid chromatography - diode array detection. Results: Peaks consistent with the chromatograms and UV-scans of the lidocaine hydrochloride reference substance were detected in the gastroscopic lubricant paste for the test. Conclusion: This method is specific, sensitive and easy to operate. It can be used as an effective method to analyze and detect illegally added lidocaine hydrochloride.
