Abstract

This study investigated the phytochemical constituents, proximate analysis, antioxidant, antimicrobial properties of methanolic leaf extracts of Aspidopterys canarensis Dalz. Results indicated the presence of acidic compounds, phenols, flavonoids, alkaloids, tannins, terpenoids, steroids, carbohydrates and reducing sugar. The proximate analysis showed it has good amount of crude fibre (39.66%) while crude ash (1.0 %) was the least other compounds were protein (0.083 mg/ml), amino acids (0.026mg/ml) and carbohydrate (0.135 mg/ml).The total antioxidant capacity of plant was 60%. The antimicrobial activities of the extracts of A. canarensis were studied against five pathogenic bacterial strains and five fungal strains. The antibacterial activity index of A. canarensis was found to be highest against Staphylococcus aureus and least to Enterobacter aerogenes. The maximum antifungal property of the methanol extract of the leaves were found 90.59% inhibition to the growth of Phytophthora capsici followed by Curvularia geniculate (82.42%) and more than 45% inhibition showed to all the other tested organisms. The results of this study indicate that leaf extracts of A. canarensis possess antioxidant, anti-microbial activities which explain its use in animal nutrition and human medicine.
