Antifungal activity of selected volatile essential oils against Penicillium sp.

Abstract

Phytopathogenic fungi have been responsible for considerable economic losses in vineyards, and therefore, more attention should be paid to the development and implementation of preventative treatment that is environmentally friendly. The aim of this study was to evaluate the antifungal activity of ten essential oils (EOs) (viz. Lavandula angustifolia Mill., Carum carvi L., Pinus mugo var. pumilio, Mentha piperita L., Foeniculum vulgare L., Pinus sylvestris L., Satureja hortensis L., Origanum vulgare L., Pimpinella anisum L. and Rosmarinus officinalis L.). For the antifungal activity evaluation against Penicillium brevicompactum, P. citrinum, P. crustosum, P. expansum, P. funiculosum, P. glabrum, P. chrysogenum, P. oxalicum, P. polonicum and Talaromyces purpurogenus a disc diffusion method was used. The ten EOs exhibited different antifungal properties. Three tested EOs (Carum carvi L., Satureja hortensis L. and Pimpinella anisum L.) at concentrations of 0.75, 0.50, 0.25 and 0.125 µL/mL showed antifungal activity, inhibiting the mycelial growth. The Origanum vulgare L. EOs exhibited a lower level of inhibition. Overall, Lavandula angustifolia Mill., Pinus mugo var. pumilio, Mentha piperita L., Foeniculum vulgare L., Pinus sylvestris L., Satureja hortensis L., Pimpinella anisum L. and Rosmarinus officinalis L. were effective as fungicidal agents but their efficiency varied between the strains of fungi. Carum carvi L. showed strong antifungal activity against all tested strains at both full strength and reduced concentrations. These EOs could be considered as potential sources of antifungal compounds for treating plant fungal diseases.

Assessment of Chemical Composition and Anti-Penicillium Activity of Vapours of Essential Oils from Abies Alba and Two Melaleuca Species in Food Model Systems

“…Many studies indicated antifungal efficacy of different EOs types against a wide range of fungal strains such as Penicillium spp. ( P. polonicum , P. expansum , P. citrinum , P. crustosum , P. funiculosum , P. brevicompactum , P. glabrum , P. oxalicum , P. chrysogenum ) [ 32 , 33 ]. Very strong antifungal action of the highest REO concentration against P. citrinum growth observed in our study is reinforced by the work of Farag et al [ 18 ], whose REO (in the concentration of 5 µL on the filter paper discs) exhibited the highest inhibitory effects (inhibition zone 18.3 mm) on the growth of Aspergillus (A.)…”

Plant Extracts Containing Saponins Affects the Stability and Biological Activity of Hempseed Oil Emulsion System

“…What is more, plant extracts are widely investigated as preservatives in foods because of their ability to inhibit bacteria growth [53,54]. Some authors reported bacteriostatic and antifungal properties depending on essential oils preparation [55][56][57]. Furthermore, Smułek et al [22] investigated the toxicity of Saponaria extract and concluded that the extract was toxic against Achromobacter sp.…”
