Qualitative phytochemical screening of leaf extract of Gmelina philippensis Cham and assessment of its antioxidant and antibacterial activity in different solvents

Abstract

The phytochemicals that are present in plants are responsible for their medicinal properties. These phytochemicals play an important role in the treatment of various diseases. The current paper is designed to investigate the bioactive compounds, antioxidant activity, and antimicrobial activity of Gmelina philippensis Cham leaf extract in various solvents. Standard methods were used to screen Gmelina philippensis leaf extract for the presence of carbohydrates, flavonoids, coumarins, tannins, terpenoids, saponins, steroids, alkaloids, and proteins in various organic solvents in the order of increasing polarity. The antioxidant activity of Gmelina philippensis Cham leaf extract in various solvents was tested using the DPPH assay. The two gram-negative and gram-positive bacteria were used for assessing the antimicrobial activity of leaf extract. So, this plant can be used to identify natural bioactive and novel compounds that could serve as a starting point for new pharmaceutical research activities.
