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 ).
