The inhibitory activities of aqueous and solvent extracts of twelve selected medicinal plants were evaluated against biosynthesis of aflatoxin B 1 (AFB 1) by Aspergillus flavus. The A. flavus was isolated from maize, and aflatoxin B 1 biosynthesis was confirmed by comparison with standard AFB 1 using TLC method. In vivo antiaflatoxigenic efficacies of activity guided solvent extracts were determined in maize model system. All the extracts showed varying degree of antifungal and AFB 1 inhibitory

Further investigations on identification of active principles from these plants are needed to develop plant based formulations for management of A. flavus growth and AFB 1 contamination in food grains.
