“…Carvacrol and eugenol are the principal aromatic active components of oregano oil and clove oil, respectively, and have a wide spectrum antimicroorganism activity, preventing food from fungal spoilage and foodborne bacteria (Nostro et al, ). In vitro studies have showed that carvacrol and eugenol could inhibit the growth of Botrytis cinerea , Phytophthora cactorum , Cryphonectria parasitica , and Fusarium circinatum (Ochoavelasco, Navarrocruz, Veralópez, Palou, & Avilasosa, ; Santamarina et al, ). Carvacrol and eugenol exhibited high antifungal activity against R. stolonifer in vitro in the present study.…”

Peaches are in high demands because of their nutritional value and delicious flavor, but often become unmarketable due to the fungus infection. In this study, carvacrol and eugenol were used to preserve peaches. Rhizopus stolonifer growth was completely inhibited by carvacrol at 32 µl/Lair and eugenol at 64 µl/Lair. Carvacrol at 0.5 µl/Lair and eugenol at 1 µl/Lair significantly reduced the incidence and severity of soft rot decay in artificially inoculated peaches. Also, carvacrol and eugenol significantly reduced the natural incidence of soft rot disease and maintained high sensory acceptance and quality of peaches during storage. The activities of defense-related enzymes were enhanced by carvacrol and eugenol fumigation, and the contents of phenolics, flavonoids, lignin, and hydroxyproline-rich glycoprotein in these two oils treated fruit, were much higher than untreated control during storage. These observations indicted that carvacrol and eugenol could preserve peach fruit during postharvest storage. Practical applicationsCarvacrol and eugenol showed great potential application in the preservation of peach fruit during postharvest storage, exhibiting high antifungal activity against Rhizopus stolonifer and enhancing defense response to soft rot disease.

“…Use of EOs as natural and safer antifungal agents for fruits, vegetables and mushrooms also during their postharvest operations it is a very current option and of great interest. According to the study of Bill et al ., thyme essential oil vapors reduced the anthracnose disease incidence by up‐regulation of phenylalanine ammonia‐lyase (PAL) gene expression and at the same time led to down‐regulation of lipoxygenase (LOX) gene expression of two Avocado fruits variety prior to cold storage.…”

Lamiaceae is one of the largest families of flowering plants comprising about 250 genera and over 7,000 species. Most of the plants of this family are aromatic and therefore important source of essential oils. Lamiaceae are widely used as culinary herbs and reported as medicinal plants in several folk traditions. In the Mediterranean area oregano, sage, rosemary, thyme and lavender stand out for geographical diffusion and variety of uses. The aim of this review is to provide recent data dealing with the phytochemical and pharmacological studies, and the more recent applications of the essential oils and the non‐volatile phytocomplexes. This literature survey suggests how the deeper understanding of biomolecular processes in the health and food sectors as per as pest control bioremediation of cultural heritage, or interaction with human microbiome, fields, leads to the rediscovery and new potential applications of well‐known plants.

The chemical composition of commercial Syzygium aromaticum, Cinnamomum verum, and Laurus nobilis essential oils as well as their antifungal activity against four pathogenic fungi isolated from Mediterranean rice grains has been investigated. Eighty nine compounds accounting for between 98.5 and 99.4% of the total essential oil were identified. The phenylpropanoids eugenol (89.37 ± 0.29%) and eugenol (56.34 ± 0.41%), followed by eugenol acetate (19.48 ± 0.13%) were, respectively, the main compounds in clove and cinnamon essential oils, whereas large amounts of the oxygenated monoterpenes 1,8-cineole (58.07 ± 0.83%) and α-terpinyl acetate (13.05 ± 0.44%) were found in bay leaf essential oil. Clove and cinnamon oils showed the best antifungal activity results against all tested fungi. Against Alternaria alternata, clove essential oil displayed the best antifungal effect, whereas against Curvularia hawaiiensis, cinnamon essential oil was more active. Both essential oils showed a similar antifungal effect towards Fusarium proliferatum and Fusarium oxysporum. In vitro studies in inoculated rice grains showed that clove and cinnamon totally inhibited pathogenic fungal development after 30 days of incubation. In vivo studies showed that eugenol used with a polysaccharide such as agar–agar formed a fine coat which wraps the inoculated rice grains, creating a natural biofilm and reducing the development of all pathogenic fungi (80–95%) for 30 days.
