Phytochemical Screening and in vitro Antioxidant Activity of Hydro-Ethanolic Extract of Blighia sapida Stem Bark

Abstract

Blighia sapida is a plant belonging to the family of Sapindaceae. In this study we aimed to carry out the phytochemical screening of hydro-ethanolic (15%) extract of Blighia sapida stem bark and evaluate its in vitro antioxidant activity. It was found that the hydro-ethanolic extract of Blighia sapida stem bark showed the presence of saponin, flavonoid, alkaloid, phenols and ascorbic acid. It also contains trace elements zinc and selenium. Furthermore it showed some scavenging activity but not as such could be compared with the various standards used except for nitric oxide scavenging activity.
