The secondary metabolites in Lobaria pulmonaria and L. scrobiculata collected in northeast Anatolia are studied using HPLC. Constictic, nortictic and stictic acids are the major components in L. pulmonaria; in addition connorstictic, cryptostictic, and menegazziaic acids are present as minor constituents. In L. scrobiculata constictic, stictic, and usnic acids and m- scrobiculin are the major compounds; while cryptostictic and norstictic acids, and p- scrobiculin are present as minors
