| 摘 要： | 天青Ⅰ水溶液的最大吸收波长为６３３ｎｍ．肝素与天青Ⅰ水溶液反应后，其吸光度Ａ的降低与肝素浓度（效价）成正比。肝素浓度在０．０１～０．０５ｍｇ／２５ｍｌ范围内服从朗伯比尔定律，平均回收率１００．０％，变异系数０．６３％．该法可用于肝素钠注射液的效价测定。

| Abstract: | The maximum absorption wavelength of azure I aqueous solution is 633urn. Decrease in absorbance was in proportion to heparin concentration(potency)after theinteraction between heparin and azure I.The excellent linearity was obtained at the heparinconcentration ranging from 0.01 to 0.05mg/25ml.The average recovery was 100.0%.Thevariation coefficiet was 0. 63%.The method can be applied to determine the potency ofheparin sodium injection. |
