Catecholamines and methods for their identification and quantitation in biological tissues and fluids.

Catecholamines act via dopaminergic-, and adrenergic receptors, and are involved in a variety of regulatory systems. They take part in regulation of the response to stress, psychomotor activity, emotional processes, learning, sleep and memory. Due to many catecholaminergic pathways, and a wide range of functions they are involved in, both in the central nervous system and in periphery, a development of the reliable techniques for their extraction and quantitation is essential. This paper presents an overview of the currently applied methodologies for catecholamines detection and identification in various biological samples.
