Abstract

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 13C-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).
