紫外分光光度法测定长春瑞滨

Ultraviolet Spectrophotometry Method for Determination of Navelbine

目的：建立长春瑞滨的紫外分光光度测定方法。方法：采用紫外分光光度法，以268 nm 为检测波长，对长春瑞滨含量进行直接测定。结果：长春瑞滨浓度在1.0~20.0μg/mL 范围内线性关系良好。结论：紫外分光光度法简便、准确、灵敏，可用于酒石酸长春瑞滨注射液中长春瑞滨含量的测定。

Objective：To develop a ultraviolet spectrophotometry （UV）method for the determination of Navelbine （NVB）. Methods：The content of NVB was directly measured by UV spectrophotometry and 268 nm wavelength was used for the detection. Results：The NVB concentration was linear relationship with absorbance in the range of 1.0~20.0μg/mL.Conclusion：The method is simple,accurate and sensitive,which can be applied to determine the trace amount of NVB in inj ection sample.
