Appraisal of solvent system effect on bioactivity profiling of Cordia africana stem bark extracts

Phytochemicals and antioxidant and antibacterial activities of Cordia africana stem bark were evaluated. Four different solvent systems were used for extraction and the evaluation of all chemical components, antioxidant and antibacterial activities were made following established methodologies. The antioxidant activity was determined using free radical scavenging and 2,2-diphenyl-1-picrylhydrazyl (DPPH) reduction assays. The phytochemical screening study on the methanol extracts revealed the presence of different plant constituents such as alkaloids, phenolics, flavonoids, tannins terpenoids and saponins. All the extracts had significant (P
