✦ Synopsis
A very odorous compound, 4-mercapto-4-methylpentan-2-one has been identi®ed in the box tree, Buxus sempervirens L., and in broom, Sarothamnus scoparius (L.) Koch by a selective extraction of volatile thiol compounds. Although the concentration varied depending on weather and the places where samples were collected, the maximum concentration of the thiol from these plants reached ca. 22 ng/g fresh leaves (box tree) and 16 ng/g fresh stem (broom), respectively. Considering the very low perception threshold of this thiol, the characteristic aroma of these plants is due to 4-mercapto-4-methylpentan-2-one. A plant that contains this thiol abundantly has not been reported before.
