CHEMICAL CONSTITUENTS OF n-HEXANE EXTRACT OF THE VIETNAMESE LICHEN PARMOTREMA CRISTIFERUM

Abstract

Chemical data of the lichen Parmotrema cristiferum are scarce. Three compounds albifolione (1), zeorin (2), and atranorin (3) were isolated from the n-hexane extract of the lichen Parmotrema cristiferum collected in Lam Dong Province. Multiple chromatographic methods were applied. Their chemical structures were elucidated by comparing their spectroscopic data with reported data in the literature. Three compounds were known in the first time from the Parmotrema cristiferum
