Chemical constituents of the lichen Parmotrema tsavoense (Krog & Swinscow) Krog & Swinscow (Parmeliaceae)
Tóm tắt
Two major depsidones protocetraric acid (1), 8’-O-methylprotocetraric acid (2), virensic acid (3), two aliphatic acids (+)-prasorediosic acid (4), (+)-vinaprasorediosic acid A (5), and along with common lichen metabolites atranorin (6), methyl haematommate (7), methyl β-orsellinate (8), methyl orsellinate (9), zeorin (10) were isolated from the lichen Parmotrema tsavoense (Krog & Swinscow) Krog & Swinscow. Their chemical structures were established by 1D NMR, 2D NMR, high resolution ESI–MS spectroscopic analysis and comparison with those reported in the literatures. The lichen Parmotrema tsavoense has not been studied on phytochemistry.
