ANTIFUNGAL ACTIVITY ON BOTRYTIS CINEREA OF FLAVONOIDS AND DITERPENOIDS ISOLATED FROM THE SURFACE OF PSEUDOGNAPHALIUM SPP.

The activity of the extracts obtained from the resinous exudates of the plants Pseudognaphalium cheiranthifolium, P. heterotrichium, P. robustum and P. vira vira on mycelial growth of the phytopathogenic fungus Botrytis cinerea was analyzed. Ten flavones, two flavanones and three diterpenoids isolat...
