The isolation of six anthraquinones, erythroglaucin, physcion, xanthorin, emodin, fallacinal and teloschistin, from three species of the lichen genus Xanthoria (X. fallax, X. eleg?ns and A. policarpa) is reported. Physcion is the dominant anthraquinone in all species. The anthraquinones showed broad-spectrum antifungal activity and selective activity against some phytopathogenic bacterial species.
