Resumen:
Aims: The present study was aimed to search for metabolites produced by fungal strainswith antifungal activity against phytopathogens.Study Design: The pollen of four beehives each from two apiaries from two locations inArgentina (Balcarce and Mar del Plata) was studied. Nine bee pollen samples wererandomly collected from each beehive.Place and Duration of Study: Study was undertaken during 2011 on the OrganicChemistry Department and Biodiversity and Experimental Biology Department, School ofExact and Natural Sciences, University of Buenos Aires.Methodology: All of the 133 isolated strains were tested for antifungal activity. The mostbioactive strains, Myrothecium verrucaria, Nigrospora sphaerica and a levuliform mycelia,were selected for the isolation and identification of compounds responsible for theantifungal activity.Results: Seven mycotoxins, roridin A, verrucarrin A, α-β-dehydrocurvularin,phomalactones A, B, C and D, were identified spectroscopically and were the responsiblethe antifungal activity.Conclusion: Mycotoxins were isolated from beehive pollen mycoflora. This is the firstreport of the production of these mycotoxins, which are not currently targets for theanalysis of pollen or honey products.
