硫酸小诺霉素注射液的紫外分光光度测定

UV SPECTROPHOTOMETRY OF MICRONOMICIN SULFATE INJECTION

采用紫外分光光度法测定硫酸小诺霉素注射液的含量，以邻苯二醛为衍生化试剂，测定波长３３３ｎｍ。在２～２０ｕ／ｍｌ范围内呈线性关系，ｒ＝０．９９９９。平均回收率为１００．０％，ＲＳＤ为０．８２％。本法简便、快速，结果准确。

A UV spectrophotometric method is described based on the absorbance of micronomicin sulfate derivative formed with Phthalic aldehyde in 50% methanolic medium,and measured at 333 nm.The calibration graph was rectilinear for 2～20 U/ml(r=0.9999).The mean recovery was 100.0% with RSD of 0.82%.This method was simple,rapid and accurate.
