Abstract

Eterična ulja i njihovi sastojci posjeduju antifungalni, antivirusni, antibakterijski, antiparazitski i insekticidni učinak. Danas se svojstva biljnih ulja i ekstrakta ili sastojaka eteričnih ulja primjenjuju u širokom spektru uključujući zaštitu svježe i procesirane hrane, u farmaceutici, alternativnoj medicini i prirodnim terapijama. Svrha ovog rada bila je da se utvrdi antifungalni učinak eteričnih ulja kadulje, ružmarina, lavande i cimeta na rast plijesni Aspergillus ochraceus ZMPBF 318 i Penicillium expansum ZMPBF 565, potencijalnih producenata mikotoksina u tekućoj YES podlozi. Istraživanja su provedena u prisutnosti 10% (v/v) koncentracija različitih eteričnih ulja na rast plijesni Aspergillus ochraceus i Penicillium expansum kao čiste i mješovite kulture. Inhibicija rasta odabranih plijesni djelovanjem različitih eteričnih ulja istraživana je gravimetrijski. Istraživana eterična ulja inhibirala su rast plijesni. Vrlo dobar antifungalni učinak na istraživane plijesni imaju eterična ulja cimeta i lavande, dok na djelovanje ulja kadulje i ružmarina plijesni pokazuju određenu otpornost.

Abstract (english)

Essential oils and their compounds have antifungal, antiviral, antibacterial, antiparasitic and insecticide effect. Today, the properties of plant oils and extracts or ingredients of essential oils are applied in a wide range, including the protection of fresh and processed food, pharmaceutics, alternative medicine and natural therapies. The purpose of this study was to determine the antifungal effects of essential oils of sage, rosemary, lavender and cinnamon on the growth of Aspergillus ochraceus ZMPBF 318 and Penicillium expansum ZMPBF 565, potential producers of mycotoxins in the current YES media. Research is conducted in the presence of 10% (v/v) concentration of various essential oils on the growth of molds Aspergillus ochraceus and Penicillium expansum as pure and mixed culture. The inhibition of mold growth, of selected various essential oils, was investigated gravimetrically. Studied essential oils have inhibitory effect on the growth of molds. Very good antifungal effect on the investigated molds have essential oils of cinnamon and lavender, while on the action of sage and rosemary oils molds have shown some resistance.
