Abstract

The use of plants and their extracts as remedies for curing many diseases have stimulated studies for investigating the presence of effective antimicrobial substances in them. The present study investigated the antifungal activity of Umm shutour tree (kegelia africana) aqueous extracts against fungi (Aspergillus niger ). The radial growth methods were used for mycelia growth using (PDA) media. The extracts of the different parts of the tree were found to inhibit mycelia radial growth of A.niger . However, the results showed that the bark extracts were highly effective giving about (0.4 cm) and (1.6 cm) radial growth diameter at the higher concentrations (100 and 75 mg/ml, respectively). This was followed by the extracts of the fruit peel which gave about (1.2 cm) radial growth at the higher concentration, then followed by the seeds (2.3 cm), while, leaves and pulp are the lowest effective giving about (2.5 cm) and (3.1 cm) radial growth compared to the control. We recommended that, further studies should be made before the application of these findings, in the field of medicine
