Lasallic acid, a tridepside from the lichen, Lasallia asiae-orientalis

The structure of lasallic acid, extracted from the lichen Lasallia asiae-orientalis, is elucidated as 2,6-dihydroxy-3-carboxy-4-methylphenyl lecanorate by comparison of NMR data with those for the tridepsides, gyrophoric and crustinic acids.
