AU - SWAMY, KUMARA PY - 2015/03/26 Y2 - 2025/09/23 TI - Electrochemical Investigations of dopamine by gallic acid isolated from Pterocarpus marsupium Roxb carbon paste electrode : A voltammetric study JF - Research in Biotechnology JA - RIB VL - 6 IS - 2 SE - Research Articles DO - UR - https://www.updatepublishing.com/journal/index.php/rib/article/view/2466 SP - AB - <p>Gallic acid was isolated from the stem bark of <em>Pterocarpus marsupium </em>Roxb and the obtained compound was used as the modifier to study the electrochemical investigations of dopamine at modified carbon paste electrode <em>in vitro</em> by cyclic voltammetric technique. The effect of scan rate and concentration at modified carbon paste electrode shows the overall electrode process was both diffusion and adsorption-controlled. The same modified electrode was used for the detection of dopamine <em>in</em> <em>vivo</em> by differential pulse voltammetric technique. This method can also be used for other bioactive molecules.</p> ER -
