Flavonoids are a diverse group of plant secondary metabolites that contribute to many biological functions including plant defence. We examined flavone-Cglycoside concentration in a number of oat entries and found significant variation. The biological activity of flavone-C-glycosides isolated from oat cv. Quoll was tested on fungal and bacterial growth. Although the crude extract inhibited all species of Pyrenophora except than P. avenae DAR 33699, this activity could not be attributed to the flavone-C-glycosides. The active antifungal compounds remain to be identified.
