Antioxidant Activity Of Centella asiatica Leaves By DPPH Radical Scavenging Method

Abstract

The DPPH (1, 1diphenyl-2-picryl hydrazyl) radical scavenging technique was used in this work to measure the antioxidant activity of several Centella asiatica ethanolic leaves extracts. Plant species that shown that, when compared to the reference standard ascorbic acid, an alcoholic (prepared in 70% ethanolic solution) extract of the plant's leaves at higher concentrations had more antioxidant capacity. They showed significant DPPH radical scavenging antioxidant activity. Ascorbic acid and alcoholic leaves extract were found to have absorbances for reducing power of 0.0350 and 0.0580, respectively. Because flavonoids and phenols are present, ethanol extract may have the greatest antioxidant action
