Six species of lichens, such as Usnea florida, Usnea barbata, Usnea longissima, Usnea rigida, Usnea hirta and Usnea subflorida, were collected from different areas of Anatolia (district of Antalya, Karabük, Qankiri, Giresun and Trabzon) in Turkey. Their usnic acid amounts in acetone extracts were determined by HPLC. In addition, antimicrobial activities of these extracts were determined against Escherichia coli (ATCC 35218), Enterococcus faecalis (RSKK 508), Proteus mirabilis (Pasteur Ens. 235), Staphylococcus aureus, Bacillus subtilis and Bacillus megaterium. It was shown that with increasing amount of usnic acid, the antimicrobial activity increased. Usnic acid contents of Usnea species varied between 0.22-6.49% of dry weight.
从土耳其安纳托利亚的不同地区（安塔利亚区、卡拉比克、坎基里、吉雷松和特拉布宗）采集了六种地衣，如长松萝、胡须松萝、长松萝、硬松萝、毛松萝和亚花松萝。通过高效液相色谱法测定了它们在丙酮提取物中的松萝酸含量。此外，还测定了这些提取物对大肠杆菌（ATCC 35218）、粪肠球菌（RSKK 508）、奇异变形杆菌（巴斯德研究所235）、金黄色葡萄球菌、枯草芽孢杆菌和巨大芽孢杆菌的抗菌活性。结果表明，随着松萝酸含量的增加，抗菌活性增强。松萝属物种的松萝酸含量在干重的0.22%-6.49%之间变化。
