| Abstract: | Screening of 61 species of Cercospora grown on a potato-agar medium showed the presence of the phytotoxin cercosporin in 24 of them, and of dothistromin in 8. Some strains of C. beticola produce a yellow phytotoxin (CBT). The new metabolites cercosporin esters, ligustrone A, B, C, taiwapyrone, 3-methoxy-2,5,7-trihydroxy-1,4-naphthaquinone, cis-4,6-dihydroxymellein and ( ? )-11-acetyldehydrocurvularin were isolated besides the known cynodontin, ( ? )-dehydrocurvularin, (+ )-mellein and cis-3S,4S-4-hydroxymellein. |
