Abstract
Die antimykotische Wirkung mehrerer Komponenten von ätherischen Ölen wurde mit einem Agar-Diffusionstest bestimmt. Die untersuchten Substanzen sind strukturell mit Eugenol verwandt. Äquimolare Mengen wurden an mehr als zehn Schimmelpilzstämmen getestet, von denen bekannt ist, daß sie Lebensmittel kontaminieren. Iso-Eugenol, Zimtaldehyd, Carvacrol, Eugenol und Thymol zeigten die stärkste antimykotische Wirkung. Der unempfindlichste Stamm war einPenicillium verrucosum var.cyclopium, während einP. viridicatum den sensibelsten darstellte. Einige Struktur-Wirkungsbeziehungen konnten in Betracht gezogen werden. Eine aktive Konfiguration bei phenolischen Verbindungen zur Entfaltung antimykotischer Wirkung scheint die freie Hydroxylgruppe in Verbindung mit einem Aklkylsubstituenten zu sein. The antifungal activity of several components of essential oils were evaluated using a paper-disk method. The substances investigated are structurally related to eugenol. Equimolar amounts were tested on more than ten fungal strains known to contaminate food. Iso-eugenol, cinnamaldehyde, carvacrol, eugenol and thymol revealed the strongest antifungal activity. The most resistant strain appeared to bePenicillium verrucosum var.cyclopium, and the most sensitive wasP. viridicatum. Some of the structural effects were considered, including a free hydroxyl group[Keywords
