 Title    Phytochemische Untersuchungen an westeuropäischen Lasallia-Arten Phytochemical Investigations on Western European Lasallia Species  
 Abstract    The secondary product pattern o f 38 specimens o f Lasallia brigantium (Zsch.) Llano, L. hi-spaniea (Frey) Sancho & Crespo and L. pustulata (L.) Merat were investigated by HPLC. A c­ cording to previous publications gyrophoric acid, lecanoric acid and umbilicaric acid were de­ tected. Additionally two further unknown depsides were found. The presence o f the anthra-quinone skyrin, new to Lasallia, was shown for L. hispanica and L. pustulata. Skyrin is not equally distributed within the thalli but mainly concentrated in the umbilicus. In L. hispanica skyrin is located in the epihymenium, too. A correlation between secondary product pattern and thallus size or light supply does not exist.
