High-resolution capillary gas-liquid chromatography (GLC) and highly sensitive and selective nitrogen-phosphorus flame ionization detection were applied for the detection of apovincaminic acid (AVA), the main metabolite of the cerebral vasodilator vinpocetine in human plasma. AVA was recovered from plasma by ion-pair extraction and determined by GLC as its methyl ester after derivatization with diazomethane. An acid-base washing technique was used in order to a minimum. The lowest detection limit of the method is 2 ng of AVA per ml of plasma.
