    • Lichen material was collected on the west coast of France, on the rocky shore of Dinard (48°38.09′ N, 02°08.15′ W), in December 2007. It was sorted out, washed and dried under ambient atmosphere. After macroscopic and microscopic observations, comparing to a reference sample of the 'Des Abbayes' herbarium, it was identified as Lichina pygmaea (Lightf.) C. Agardh. and a voucher specimen is kept in the laboratory with the reference JB/07/98.

    • HPLC experiments were performed on a chiral column (Chiralpak® AD-H, Chiral technologies Europe, Illkirch, France). Each sample was diluted in ethanol at a concentration of 0.1 mg/mL, and after passing through a 0.45-μm membrane filter, 20 μL were injected into the column, using heptane/isopropanol (60:40) as an eluent, with a flow rate of 0.7 mL/min. Peak detection was carried out online using a UV detector at 254 nm. The retention time of 3 and 4 was 6.13 min.
