The phytochemical composition and anti-oxidant activities using Di-phenyl-1-picryl-hydrazyl (DPPH) Radical Scavenging assay, Ferric Reducing and Antioxidant Power(FRAP) and the Total Phenolic contents (TPC) of the extracts from the leaves, stem-bark and root of Nauclealatifolia.The phytochemical analysis revealed the presence of bioactive compounds in the entire plant samples. The leaves of Nauclealatifoliacontained tannins 0.17 g/100g, alkaloid 2.29 g/100g, 0.83 g/100g flavonoid and 0.56% saponin. The stem bark also contained 0.53, 2.58, 0.08 g/100g and 0.84% while the composition of the root are 0.13, 0.88, 0.32 g/100g and 0.72% tannins, alkaloids, flavonoids and saponin, respectively. The stem bark had the highest antioxidant potential; DPPH (30.60 mg/mL), FRAP (184.64 mg/GAE/g) and TPC (30.16 g/100g). Our findings provide evidence that the extract of Nauclealatifolia could be a potential source of natural antioxidants that may be used to combat stress related conditions.The phytochemical analysis supports the extensive use of the leaves bark and root of Nauclealatifoliain ethno-medicine in many parts of Africa. Overall, the result suggests that Nauclealatifolia could be a potential source of pharmacologically active natural product and/or for development of neutraceuticals.
