The phytoconstitution and antioxidant profiling of mixture of herbs used in the treatment of malaria has been carried out. Herbs used as alternative medicines in the local treatment of malaria were collected from a herbal vendor in Ibadan. The herbal materials were extracted using absolute ethanol and the crude extract, EEA subjected to qualitative phytochemical screening and 2,2-diphenyl-1-picrylhydrazyl (DPPH) standard procedures. The presence of alkaloids, saponins, tannins, terpeniods, flavonoids and phenols were identified. EEA was found to exhibit antioxidant activity in the dose range of 25-400 μgml-1. The significant presence of major series of phytochemicals has justified the associated antimalarial ethnomedicinal claim. Thus, the present study has established the phytoconstitution and antioxidant activity of an antimalaria herbal mixture.

The nutritional, mineral, Vitamin C and antioxidant capacity profiling of the nut of Spondias mombin has been carried out. The nut of S. mombin (NSM) was extracted from its fruit and then profiled quantitatively for its nutritional, mineral and vitamin C contents using the AOAC standard procedures. The antioxidant capacity of the methanol extract of NSM was carried out using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical assay and ferric reducing antioxidant potential (FRAP) techniques. The nut was found to have nutritional facts of: moisture content (12.24±0.06%), lipid content (1.69±0.01%), fibre content (45.27±0.32%), protein content (5.69±0.04%), ash content (0.41±0.02%) and carbohydrate content (34.70±0.33%). The mineral content in mg/g of sample was found to contain: K (7.014), Na (2.966), Ca (1.333), Mg (0.690), Fe (0.131), Cu (0.079), Zn (0.015), Cd (0.004) and Cr (0.009). Pb was not detected. The vitamin C content was 3.89 mg, DPPH antioxidant potential increases as concentration of NSM increases from 25.00 µg/ml to 400 µg/mL and FRAP was observed at 400 μg/ml NSM to be 75.304±0.002 mgAAE. The nut of S. mombin has shown to be good sources for alternative nutrition and as a base for minerals rich in cellular ions. The nut of S. mombin has exhibited antioxidant capacity which can be attributed to the presence of some vital phytoconstituents.
