(+)-Usnic acid, the depside atranorin, and the depsidones fumarprotocetraric, α-alectoronic, and α-collatolic acids, and also the phenoxyisocoumarin derivatives β-alectoronic and β-collatolic acids have been isolated by extraction with hexane and chloroform from lichens Asahinea chrysantha, A. scholanderi, and Parmelia birulae.This is the first time that β-alectoronic acid has been detected in lichens.The structures of the compounds have been established by spectral and chemical methods.
