A Comparative Assessment on Antioxidant and Phytochemical of Trichilia monadelpha (Thonn) J.J. De Wilde (Meliaceae) Plant Extracts

摘要

This study was designed to evaluate the phytochemical screening and antioxidant activities of Trichilia monadelpha plant extracts. The leaves were extracted using two different solvents namely-(n-hexane and methanol).? The dry or wet yield of n-hexane extract was 1.3%, while methanolic extract exhibited a percentage yield of 3.7 %.? Phytochemical research revealed the presence of secondary plant metabolites such as; alkaloids, flavonoids, cardiac glycosides, terpenoids and saponins. In-vitro antioxidant activity was determined using three assays (DPPH free radical scavenging assay, reducing ability and hydroxy radical scavenging activity) with four concentrations (0.25, 5.0, 1.0 and 2.0 mg/L), vitamin C was also used as a standard antioxidant.
