Abstract

Parmotrema planatilobatum (Hale) Hale is a lichen which has not been chemically and biologically studied. From the lichen collected in Viet Nam, seven compounds were isolated, including methyl β-orsellinate (1), methyl orsellinate (2), orsellinic acid (3), methyl haematommate (4), atranorin (5), lecanoric acid (6) and (+)-(12R)-usnic acid (7). The structures of these compounds were elucidated by spectroscopic data and compared with those in references. This is the fisrt time that these compounds are known in Parmotrema planatilobatum (Hale) Hale.
