Three New Sesquiterpene Aryl Esters from the Mycelium of Armillaria mellea

Abstract
Three new sesquiterpene aryl esters and eight known compounds were isolated from the EtOH extract of the mycelium of Armillaria mellea. The structures of new compounds were established by analysis of their spectroscopic data. Some of the isolates showed cytotoxicity to a variety of cancer cell lines, including MCF-7, H460, HT-29, and CEM.
