Table 4. Identified secondary metabolites in dual culture (barley-malt medium with Hymenoscyphus fraxineus) of the surveyed strains listed in Table 3. Identified compounds: 5: phomopsidin; 6: 10-hydroxyphomopsidin; 8: rickiol A; 9: orthosporin; 10: daldinone B; 11: 1,8-dimethoxynaphtahlene; 13: 5-methyl-mellein. Identified stromal azaphilone groups detected in culture: MI = Mitorubrin type; NA = Naphthalene type; DA = Daldinin type. For chemical structures, see Fig. 8.
