✦ Synopsis

Identification and synthesis of new depsides isolated from oakmoss (Evernia Prunastri (L.) ACH.)

Lecanoric acid 5 and 4 new depsides have been isolated from oakmoss (Evernia Prunastri (L.) ACH.) extracts by means of silicagel column chromatography. Various spectral methods including ^13^C‐NMR. were used in determining the structure of 4,2″‐O‐methylgyrophoric acid (1), lecanoric acid (5), 2′‐O‐methylevernic acid (2), 3′‐methylevernic acid (3) and methyl 3′‐methyllecanorate (4).

## Abstract The composition of different oakmoss extracts was investigated by combined gas chromatography/mass spectrometry. A series of 38 compounds – especially phenol derivatives and monoterpenes – was identified, 22 of which have not yet been reported as constituents of oakmoss.
