Representative components of various lichen substances, according to the classification forwarded by Prof. Asahina, were chosen to test their growth inhibitory actions in vitro against bacteria. Antibacterial effect against Gram-positive bacteria were found with compounds of lichesterinic acid series and depsides of orcinol series where there were a large number of carbon atoms in their alkyl radical. No such properties were found with fatty acids of caperatic acid type, zeorin series compounds, depsides of β-orcinol series and depsidones. None showed any antibacterial action against Gram-negative bacteria.
