双波长分光光度法测定盐酸去氧肾上腺素滴眼液的含量

Double wavelength spectrophotometric determination of phenylephrine hydrochloride eye drops

本文应用双波长分光光度法测定盐酸去氧肾上腺素的含量,消除了处方中防腐剂尼泊金乙酯的干扰。盐酸去氧肾上腺素在20～100μg/ml 的浓度范围内,AA 与浓度呈线性关系,γ=1.0000。

A double wavelength spectrophotometry method was employed to determine phenylephrine hydrochloride in eye drops.Theinterference of antiseptic in the formula is eliminated by this method.
