采用薄层色谱法检测阿片类成瘾者尿中的吗啡,可定性及半定量。方法适用于临床快速检验。薄板为硅胶G板,展开系统为乙酸乙酯:甲醇:氨水=80:15∶5,Dra-gendorff与碘铂酸钾两种显色剂先后显色,吗啡呈现特殊的蓝紫色斑点,最低检出量达0.1μg/点,较单一显色剂显色灵敏度提高5～10倍。在合并用药的情况下均能测得尿中吗啡而不受干扰,通过对昆明、西安两地戒毒所中124例吸毒成瘾者尿样的检测,结果令人满意。 Determination of morphine in the urine of opiate addicts by TLC is qualitative and semi-quantitative. The method is suitable for clinical rapid test. The plate was made of silica gel G plate, and the developing system was ethyl acetate: methanol: ammonia = 80: 15: 5. Dragendorff and potassium iodoplatinate developed color, morphine showed special purple spots, The amount of 0.1μg / point, compared with a single color reagent sensitivity increased 5 to 10 times. Urine morphine can be measured without interference in the case of combined medication. The results of 124 urine samples from drug addicts in Kunming and Xi’an were satisfactory.
