O-Demethylfonsecin
O-Demethylfonsecin is a pigment from a mutant of Aspergillus fonsecaeus also known as Aspergillus carbonarius. YWA1 is a heptaketide that is 2,3-dihydro-4H-benzo[g]chromen-4-one bearing a methyl substituent at position 2 and four hydroxy substituents at positions 2, 5, 6 and 8. It has a role as an Aspergillus metabolite. It is a naphtho-gamma-pyrone, a cyclic hemiketal, a member of phenols and a heptaketide.
