本文采用钙盐沉淀法和高效薄层层析法分离阿片试样中的吗啡,采用碱性铁氰化钾溶液将吗啡氧化为高荧光的二聚伪吗啡,荧光扫描测定吗啡含量。测定了药用阿片中的吗啡含量,试样测定的平均回收率为94.5%。
In this paper, morphine was isolated from the opioid samples by calcium salt precipitation method and high performance thin layer chromatography. Morphine was oxidized to the highly fluorescent dimeric pseudo-morphine by alkaline potassium ferricyanide solution. The morphine content was determined by fluorescence scanning. The morphine content of the medicinal opium tablets was determined. The average recovery of the sample was 94.5%.
