Until recently only two mixed orcinol P-orcinol depsides were known, namely obtusatic acid (210) and norobtusatic acid (211), but now a further four such compounds have been reported. These include 2-0-methylobtusatic acid (212) present in Xanthoparmelia tucsonensis 45) and evernine (213) 253), 3 -methylevernic acid (214) 252) and methyl 3 -methyllecanorate (215) 252) all obtained from Evernia prunastri. [Pg.145]
