The antimicrobial activity of the diethyl ether, acetone, chloroform, petroleum ether, and ethanol extracts of the lichen Xanthoparmelia pokornyi and its gyrophoric acid and stenosporic acid constituents has been screened against some foodborne bacteria and fungi. Both the extracts and the acids showed antimicrobial activity against Aeromonas hydrophila, Bacillus cereus, Bacillus subtilis, Listeria monocytogenes, Proteus vulgaris, Staphylococcus aureus, Streptococcus faecalis, Yersinia enterocolitica, Candida albicans and Candida glabrata. The extracts were inactive against the tested filamentous fungi. The MIC values of the extracts and the acids for the bacteria have also been determined.
对黄髓梅衣（Xanthoparmelia pokornyi）及其成分石耳酸和狭孢酸的乙醚、丙酮、氯仿、石油醚和乙醇提取物针对一些食源细菌和真菌的抗菌活性进行了筛选。提取物和酸对嗜水气单胞菌、蜡样芽孢杆菌、枯草芽孢杆菌、单核细胞增生李斯特菌、普通变形杆菌、金黄色葡萄球菌、粪肠球菌、小肠结肠炎耶尔森菌、白色念珠菌和光滑念珠菌均表现出抗菌活性。提取物对测试的丝状真菌无活性。还测定了提取物和酸对细菌的最低抑菌浓度（MIC）值。
