Abstract
A fluorescence assay for metaraminol bitartrate injection has been developed which uses o-phthalaldehyde as a fluorogenic reagent, and dose not require prior isolation of metaraminol. It is 50 times more sensitive than the USP assay. Six analyses of 2 vials of the same lot of metaraminol bitartrate injection gave 96 +/- 0.4% of label declaration.
摘要
已开发出一种用于重酒石酸间羟胺注射液的荧光测定法，该方法使用邻苯二甲醛作为荧光试剂，且无需事先分离间羟胺。其灵敏度是美国药典测定法的50倍。对同一批次的2瓶重酒石酸间羟胺注射液进行6次分析，结果为标示量的96±0.4%。
