Abstract

Investigation of the secondary metabolites of the solid-state rice cultures from the European basidiomycetes Terana coerulea and Sparassis brevipes afforded three previously undescribed secondary metabolites identified as two p-terphenyl derivatives (1 and 2) and one orsellinic acid congener (3) in addition to another known, isoeverninic acid (4). Chemical structures of the isolated compounds were elucidated through comprehensive 1D and 2D NMR spectroscopic analyses, coupled with HR-MS and other spectral methods. The isolated compounds were assessed for their cytotoxic and antimicrobial activities. Compound 1 revealed weak antimicrobial properties, whereas the inseparable mixture of 3 and 4 featured moderate cytotoxic and antimicrobial effects.
