ANTIFUNGAL SPECTRUM OF FLAVONE AND FLAVANONE TESTED AGAINST 34 DIFFERENT FUNGI

The antifungal activity of flavone and flavanone was tested in three d ifferent concentrations, 0.5, 2 and 8 x 10(-4) M, against 34 fungi. In general, flavone was the substance with the higher activity, and coul d at 2 x 10(-4) M completely inhibit several fungi. No linear relation ships between the concentration and the antifungal activity could be o bserved for some fungi. Chaetomium globosum was the only fungus which was totally inhibited by flavanone at 8 x 10(-4) M. Several fungi did, however, show a higher inhibition rate at 2 x 10(-4) M.
