selectively inhibit monoamine oxidase (MAO) by in‐vitro tests. Monoamine oxidase was isolated and purified from the mitochondrial extracts of rat‐liver homogenates and human platelets. Monoamine oxidase inhibitory activities of the compounds were compared with pargyline and clorgyline. Most of the compounds inhibited the total activity of rat liver homogenates. The monoamine oxidase‐A inhibitory effects of
