Nanoparticles of carbon derivatized from pyrolysis of biowaste oil palm leaves were processed as electrochemical transducer material at the interface of glassy carbon electrode. This modified electrode exhibits convincing electron‐transfer property for voltammetric and chronoamperometric quantification of clinically important phytochemical, butein, without the use of external redox mediator and enzyme. A reversible two‐electron transfer redox property observed from butein is distinct at the electrode interface and the current density is found to be superior in phosphate buffered saline electrolyte at pH 7.0. Carbon nanoparticles interfaced electrode system displayed a good stability and sensitivity for butein with a detection limit of 7.6 μM and a dynamic detection concentration ranging from 10 to 100 μM. This bio‐waste translated carbon nanoparticle represent a promising electrode material for various flavonoids detection useful for biological studies.
