Abstract

Two isocoumarins (6-methoxymellein and 6-hydroxymellein), one pyrrole compound (minaline), one lactone derivative (butyrolactone II), five phenolic acids (phenylacetic, veratric (3,4-dimethoxybenzoic), 4-hydroxyphenylacetic, 4-hydroxybenzoic and protocatechuic acid), and two phenolic acid methyl esters ((2-hydroxyphenyl) acetic acid methyl ester and methyl 4-hydroxyphenylacetate), along with 1,3-bis(4-hydroxyphenyl) propan-2-one were isolated from the fungal strain Aspergillus terreus XJA8. The fungal strain was isolated from the root of the medicinal plant Vernonia anthelmintica for first time. All isolated secondary metabolites were evaluated for their antimicrobial activity and melanin synthesis in murine B16 cells.
