Chemical investigation of the Antarctic lichen Usnea aurantiaco-atra led to the isolation and identification of eight compounds, including a dibenzofuran derivative (1), three phenolics (2, 7, 8), a p-terphenyl (3), and three sterols (4-6). The structures of the isolated compounds (1-8) were elucidated by 1H and 13C NMR spectroscopic ana-lyses and comparisons with previously reported data. All compounds (1-8) were isolated from this species for the first time. The current study is also the first …
