Phytochemical Screening and in-Vitro Antioxidant Activity on Vernonia Amygdalina (Ewuro- Bitter Leaf) (Published)
Most of the plants exhibit a variety of phyto-pharmaceuticals, which have important applications in the fields of agriculture, human and veterinary medicine. This study was conducted to evaluate phytochemical screening and in-vitro antioxidant activity on Vernonia amygdalina (bitter leaf) at the Department of Biological Sciences, Federal Polytechnic, Ado Ekiti. It was revealed that the phytochemical constituents in Bitter leaf (Vernonia amygdalina) were alkaloids, saponin, tannins, terpenoids, flavonoids and cardiac glycosides in the extract. Anti-oxidant property results of the aqueous extract of Bitter leaf (Vernonia amygdalina) showed Total phenolic content was 120.16mg Gallic acid equivalent/g extract while the total flavonoid was 235.147mg Quercetin equivalent/g extract. The plant could be exploited as source of antioxidant additives and used for future project to evaluate the potentials of Bitter leaf (Vernonia amygdalina) as a strong medicinal plant in improving human health status.
