Determination of usnic acid content in some lichen species found in anatolia

85 species of lichens were collected from Anatolia (Ankara, Antalya, Bursa, Karabük, Giresun, Trabzon, Çankırı, Kayseri and Gümüşhane) in Turkey. Their usnic acid amounts were determined by HPLC in acetone extracts and the data obtained were evaluated statistically. Results showed that usnic acid contents of lichen species varied between 6.49 – 0.04 dry weight percentages.
