Rapid Determination of Quinidine in Human Plasma by High-Performance Liquid Chromatography

Raja G. Achari, J. L. Baldridge, Theodore R. Koziol, L. Yu

Abstract

A sensitive and specific method for the determination of quinidine in plasma is described. Quinidine is extracted with chloroform, the extract is evaporated and reconstituted with methanol and the methanol extract is analyzed by high-performance liquid chromatography using a silica gel column. The recovery of quinidine from plasma varied between 93.0 to 100%. Quinidine levels as low as 12 ng/ml can be detected by this method.
