Abstract
In vitro antioxidant activity of plant extracts refers to the ability of plant-derived compounds to neutralize harmful free radicals in a laboratory setting, preventing oxidative damage. These compounds, often phenolics, flavonoids, and other phytochemicals, can be assessed through various assays. The intention of this study is to evaluate the in vitro antioxidant activity of ethanolic extraction of the leaves of Erythrina variegata. The DPPH, superoxide anion scavenging, hydroxyl radical scavenging, nitric oxide scavenging and hydrogen peroxide scavenging methods were used to investigate in vitro antioxidant capabilities. Furthermore, medicinal plants are a very respectable source of lead compounds for the development of new drugs with few adverse reactions. The findings also showed that the antioxidant activity of the ethanolic extract of Erythrina variegata leaves was significantly higher at the various concentrations (20, 40, 60, 80, and 100?g/ml) than the standard (ascorbic acid) for DPPH, superoxide anion scavenging, hydroxyl radical scavenging, nitric oxide scavenging and hydrogen peroxide scavenging. The current study aims to identify a new herbal treatment for oxidative stress from Erythrina variegata.
