Three species of lichens, Rhizoplaca chrysoleuca (Sm.) Zopf, Rhizoplaca melanopthalma (DC.) Leuckert & Poelt and Rhizoplaca peltata Ramonds Leuckert, were collected from middle Anatolia, Erciyes Mountain (Kayseri) in Turkey. Their usnic acid amounts were determined by HPLC in acetone extracts. 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, Bacillus megaterium and Pseudomonas aeruginosa. It was shown that, as the usnic acid amount increased, the antimicrobial activities increased too. The usnic acid contents of Rhizoplaca species varied between 0.19-4.0% dry weight.
从土耳其安纳托利亚中部的埃尔西耶斯山（开塞利）采集了三种地衣，分别是黄盘衣（Rhizoplaca chrysoleuca (Sm.) Zopf）、黑眼盘衣（Rhizoplaca melanopthalma (DC.) Leuckert & Poelt）和盾盘衣（Rhizoplaca peltata Ramonds Leuckert）。通过高效液相色谱法测定了它们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株）、金黄色葡萄球菌、枯草芽孢杆菌、巨大芽孢杆菌和铜绿假单胞菌的抗菌活性。结果表明，随着松萝酸含量的增加，抗菌活性也随之增加。盘衣属地衣的松萝酸含量在干重的0.19%至4.0%之间变化。
