Resorcinol is dihydroxy benzene and the stem extracted resorcinols have medicinal importance and is widely used as antiseptic and disinfectant. Electron transfer plays a fundamental role in governing the pathway of chemical reactions. Generally voltammetry is the electrochemical technique in which the current at an electrode is measured as a function of the potential or voltage applied to the electrode. Cyclic voltammetry is the most versatile electroanalytical technique for the study of electroactive species. It is used in all fields of chemical and biological sciences as a means of studying redox states. The crude ethanol extract of Pterocarpus marsupium RoxB was analysed by cyclic voltammetric technique and it shows the presence of higher concentration of resorcinol. The effect of concentration and scan rate was varied for the crude ethanol extract at bare carbon paste electrode. The technique adopted was very easy, shows good reproducibility and high stability in its voltammetric response. This method can be used for the identification of some bioactive molecules.
