A New Orsellinic Acid Derivative from the Fungus Chaetomium megalocarpum

  • Published:
Chemistry of Natural Compounds Aims and scope

A new orsellinic acid derivative, orsellide A1, together with orsellide A, orsellide D, and orsellinic acid, was isolated from the ethyl acetate extract of the solid-state fermented rice culture of the Chaetomium megalocarpum cib-135 fungus. The structure of orsellide A1 (1) was confirmed to be 2-O-(2,4-dihydroxy-6-methylbenzoyl)-6-deoxy-1-O-ethyl-3-keto-α-D-ribo-hexopyranoside on the basis of spectroscopic analysis.
