ABSTRACT

The concentration of the bioactive compound 2h-Furo[2,3-H]-1- Benzopyran-2-One isolated from seeds of Psoralea corylifolia L on the dry mycelial weight and total inhibition of Fusarium species were tested in vitro condition. The concentration of the bioactive compound needed for total inhibition of mycelial growth varied between 450ppm and 650ppm for the different species of Fusarium tested. F. moniliforme was totally inhibited at a concentration as low as 450ppm whereas, F. proliferatum and F.equiseiti were totally inhibited at 650ppm concentration. The MIC values of the bioactive compound for total inhibition of Fusarium species was also evaluated.

Keywords: P.corylifolia, dry mycelia weight, Fusarium species, antifungal activity.
