Abstract: Rezumat In lucrare este prezentată evaluarea comparativă a eficienţei metodelor cu cheltuieli reduse de preparare a probelor de plasmă sau ser sanguin pentru investigarea ulterioară prin metoda HPLC cu fază inversă, bazate pe deproteinizarea cu diverşi precipitând şi extracţia omogenă. S-a determinat domeniul posibil de utilizare al fiecărei metode în funcţie de proprietăţile substanţelor analizate. Sunt făcute recomandări privind selectarea unei metode optime de preparare a probelor la elaborarea noilor metode de dozare a substanţelor medicamentoase în material biologic. Summary. The comparative evaluation of low-cost methods of biological samples preparation in pharmacokinetic researches. In paper the comparative estimation of some low-cost methods of sample preparation of blood plasma and serum to its ulterior research by the reversed-phase HPLC is given, based on depro- teinization by the various précipitants and single-phase extraction. The limits of possible usage of each method in dependence on properties of analytical substances have been determined. The guidelines for a choice of an optimum method of biological samples preparation at new analytical methods development for the active substances determination are given.
