In the category of medicinal plants with remarkable therapeutic properties, lichens are also included. An important representative of this group is the Usnea Adans. genus, with over 650 species spread throughout the globe. Representative species of this genus were also found in Romania, so the studies were conducted on Usnea barbata (L.) F.H.Wigg., harvested from the Calimani Mountains, Suceava County. The objectives of this research are: obtaining the dry extract of the Usneae lichen followed by the identification and determination of the usnic acid content by ultra-high performance liquid chromatography (UHPLC) method. Usnic acid content determined in dry extract of Usnea barbata (L.) F.H.Wigg. was significant, of 16.53  6.53% (mean  RSD), which supports the continuation of the research with the evaluation of biological effects (antibacterial, antioxidant and antitumoral).
