“…The essential oil originating from France showed low inhibitory activity against Grampositive bacteria Bacillus subtilis and Staphylococcus aureus and possessed a higher zone of inhibition (18.00 mm) against Aspergillus brasiliensis. Our results are in agreement with results reported by Mesic et al (2019) that immortelle essential oil inhibited only Gram-positive bacteria and possessed antifungal effects. The established difference in antimicrobial activity of the two tested essential oils is explained by the different contents of oxygen derivatives that have higher antimicrobial action than hydrocarbons (Baser and Buchbauer, 2010).…”

The chemical composition and the antimicrobial and antioxidant activity of essential oils from two Helichrysum italicum (Roth) G.Don subspecies grown in Bulgaria were investigated. As a result, 95 compounds with concentrations above 0.05% were detected by GC/MS and 46 of them, mainly mono-and sesquiterpenes, representing 79.81% and 85.51% of the total content of the samples, were identified. The main constituents of the essential oil from Helichrysum italicum subsp. microphyllum (plant origin from Bosnia) were monoterpene α-pinene (20.84%) and sesquiterpene γ-curcumene (16.53%), followed by β-selinene (5.59%), ar-curcumene (4.39%), trans-caryophyllene (4.35%), β-diketone italidione I (4.32%), α-selinene (4.28%), and neryl acetate (3.81%). The sesquiterpene hydrocarbons were the dominant groups of chemical constituents in the essential oil, followed by the oxygenated aliphatic hydrocarbons. The main constituents in the H. italicum essential oil (plant origin from France) were neryl acetate (33.87%), γ-curcumene (8.84%), rosifoliol (5.46%), geranyl propionate (4.98%), αr-curcumene (4.31%), italidione I (3.56%), α-eudesmol (3.19%), and limonene (3.02%). The main class of chemical compounds was the oxygenated monoterpenes, followed by sesquiterpene hydrocarbons. H. italicum essential oil from France showed more pronounced antimicrobial activity against the Gram-positive bacteria Staphylococcus aureus and Bacillus subtilis, and the fungus Aspergillus brasiliensis, as well as stronger antioxidant potential.

“…(2016) and Mesic et al . (2021) found that these components damaged the lipid layer of the bacterial membrane, resulting in the leakage of crucial macromolecules such as protein, ATP, and DNA. Furthermore, EOs disrupted bacterial respiratory metabolism, and its particular components caused irreversible chromosomal and DNA damage and the suppression of mitotic processes, which resulted in cell death (Cui et al .…”

Significance and Impact of this Study:The biofilm and viable but non-culturable state (VBNC) of Listeria monocytogenes are regarded as potential harms to public health. It is of great significance to apply lavender essential oil (LEO) as an alternative of disinfectant and antibiotics to control the pathogenicity and drug resistance of pathogens enhanced by biofilms. This work mainly evaluated the elimination effects of LEO on L. monocytogenes biofilms formed at 32°C (warm biofilm) and 10°C (cold biofilm). The results presented that LEO exhibited effective eradicating effects on L. monocytogenes biofilms formed at different temperatures, significantly reduced the VBNC cell number in mature biofilms and promoted the dispersion of biofilm cells into plankton. Our findings support that LEO has the potential to be applied as an ideal antibiofilm agent to control the contamination and infection of L. monocytogenes.

“…The obtained results from this study are in good agreement with the findings of Cantore et al [ 61 ] who reported that G + bacteria are more sensitive to plant EOs than G − bacteria. Mesic et al [ 62 ] reported that immortelle essential oil inhibited only Gram-positive bacteria and possessed antifungal effects.…”

This study compared the essential oils (EO) composition of Helichrysum arenarium (Bulgarian populations) with that of the cultivated species H. italicum. The EO composition of H. arenarium and H. italicum were analyzed via gas chromatography. In general, 75 components were identified in H. arenarium EO and 79 in H. italicum EO. The predominant constituents in H. arenarium EO were α-pinene (34.64–44.35%) and sabinene (10.63–11.1%), which affirmed the examined population as a new chemical type. Overall, the main EO constituents of H. italicum originating in France, Bosnia and Corsica were neryl acetate (4.04–14.87%) and β-himachalene (9.9–10.99%). However, the EOs profile of H. italicum introduced from the above three countries differed to some extent. D-limonene (5.23%), italicene, α-guaiene and neryl acetate (14.87%) predominated in the H. italicum introduced from France, while α-pinene (13.74%), δ-cadinene (5.51%), α-cadinene (3.3%), β-caryophyllene (3.65%) and α-calacorene (1.63%) predominated in plants introduced from Bosnia. The EOs of the plants introduced from France and Corsica had similar chemical composition and antimicrobiological activity.
