Evaluation of Phytochemical and Antioxidant Activity of Tridax procumbens Extract

Abstract

Oxidative stress and impaired antioxidant system have been implicated in the pathophysiology of diverse disease states. The polyphenol and flavonoids are used for the treatment of various diseases triggered by oxidative stress. Tridax procumbens have been used as indigenous medicine for a variety of ailments. In the present study, it was planned to investigate the phytochemical and in vitro antioxidant activity of the ethanol, methanol and aqueous extracts of Tridax procumbens leaves. The ethanol, methanol and aqueous extracts of Tridax procumbens leaves were prepared and performed its phytochemical analysis. The in vitro antioxidant activity namely DPPH, total polyphenol content, total flavonol content and reducing power assay were performed. The qualitative chemical test exhibited the presence of alkaloids, polyphenol, tannins, flavonoids, carbohydrates, saponin and glycoside in ethanol, methanol and aqueous extracts of Tridax procumbens. The findings of in vitro antioxidant activity demonstrated that ethanol extracts expressed higher antioxidant activity compared to methanol and aqueous extract. These results are an indication of antioxidant potential of the extracts and may be responsible for some of the therapeutic uses of Tridax procumbens.
