Summary

Two pigments responsible for the yellow-orange color of a brown conidiating mutant of the deuteromyceteTrichoderma viride were isolated and spectroscopically identified as 1,3,6,8-tetrahydroxyanthraquinone (I) and 1-acetyl-2,4,5,7-tetrahydroxy-9,10-anthracenedione (II). Both compounds are known substances but were not yet reported as metabolites of this fungal species. Their relationship to other anthraquinones produced byT. viride is discussed.
