本文报道一种简便、准确的测定肾上腺素(EP)、去甲肾上腺素(NE)及其酒石酸盐的分光光度法。其原理是该药物在含水的乙醇溶液中与高碘酸钠反应生成红色化合物(λmax490nm),EP或NE与高碘酸盐摩尔反应比为1:2。本方法特别适合EP和NE注
This article reports a simple and accurate spectrophotometric method for the determination of epinephrine (EP), norepinephrine (NE) and its tartrate. The principle is that the drug reacts with sodium periodate to form a red compound (λ max 490 nm) in an aqueous ethanol solution with a molar ratio of EP or NE to periodate of 1: 2. This method is particularly suitable for EP and NE notes
