“…Many methods for the separation and determination of adenosine in biological samples have been developed. These methods include high performance liquid chromatography (HPLC) [8][9][10][11][12][13][14][15][16][17], co-electroosmotic capillary electrophores [18] and flow-injection method [19]. Of these methods, the most useful one for the determination of adenosine in biological samples is HPLC method.…”
