Two New Phenolic Compounds from the Antarctic Lichen Pertusaria dactylina

Abstract

Two new phenolic compounds, methyl-2-hydroxy-4-methoxy-6-(2-oxopentyl)-benzoate (1) and 4-methoxy-6-pentyl-1,2-dihydroxybenzene (2), together with two known phenolic derivatives were isolated from the Antarctic lichen, Pertusaria dactylina (Pertusariaceae). The structures of the new compounds were determined by 1D and 2D NMR, and HRMS experiments, as well as by comparison of their data with the published values.
