Abstract
The new depsidone subpsoromic acid (4-formyl-3-hydroxy-8-methoxy-1-methyl-11-oxo-11H-dibenzo[b,e]-[1,4]dioxepin-6-carboxylic acid) (6) has been isolated from the lichen Ocellularia praestans and the structure (6) deduced from a combination of spectroscopic data.Keywords: Depsidone; lichen; mass spectrometry; natural product; n.m.r.
