“…In recent years, various applications of essential oil components (EOCs) have been studied extensively due to market preferences for natural chemicals and growing concerns about the health and environmental safety of synthetic chemicals . Due to their antimicrobial activity, EOCs have emerged as suitable alternatives to synthetic pesticides, food preservatives, cosmetics, or pharmaceutical products, and essential oils and their components are in high demand in a number of industries …”

Essential oil components (EOCs) are potent natural antimicrobial agents, but their high volatility and reactivity limit their potential applications. Here, we report the preparation of a series of nanomaterials containing EOCs (i.e., allyl isothiocyanate, carvacrol, cinnamaldehyde, diallyl disulphide, eugenol and thymol). The materials were prepared by simple adsorption of the EOCs onto a montmorillonite nanoclay. The antimicrobial activities of these materials were assessed against Aspergillus niger and Staphylococcus aureus as typical models of agricultural fungal pathogens and foodborne bacterial pathogens, respectively. In addition, the activities of the encapsulated EOCs were compared with those of the corresponding free forms with or without Tween‐80 in two types of assays: microdilution assays for determining the minimum inhibitory concentration (MIC) and agar‐based assays mimicking surface treatment. Enhanced antifungal activity of the encapsulated form was observed for all EOCs. In addition, against S. aureus, the MICs of all EOCs were remarkably lower in encapsulated form than in free form. These results indicate that EOCs encapsulated in low‐cost nanoclays have favourable potential as antimicrobials compared with the pure compounds.

“…Nevertheless, there are reports of the use of roots to obtain the essential oil of E. adenophorum Spreng. (Ahluwalia et al, 2014) and the aqueous extract of E. purpureum L. (Carlson et al, 1948;Pates Madsen, 1955), in both cases having antibacterial action.…”

“…The essential oil extracted from the flowers, and roots was tested and showed inhibitory activity for the strains of Xanthomonas oryzae, Erwinia chrysanthemi, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae. Assays were performed using the disk diffusion and agar dilution methods (Ahluwalia et al, 2014). The essential oil extracted from the aerial parts was also investigated against strains of Arthrobacter protophormiae, Escherichia coli, Micrococcus luteus, Rhodococcus rhodochrous and Staphylococcus aureus.…”

“…Assays were performed by broth dilution and the results showed growth inhibition for all strains tested (Kurade et (Kundu et al, 2013). Ahluwalia et al (2014) analyzed the antifungal action of the essential oil of E. adenophorum against five pathogenic fungi: Sclerotium rolfsii, Macrophomina phaseolina, Rhizoctonia solani, Pythium debaryanum and Fusarium oxysporum. They found the strongest inhibitory activity against S. rolfsii.…”

In recent years, the number of infectious diseases linked to the occurrence of bacterial and fungal resistance has increased, leading to extensive search for new drugs to treat these infections. Species of the Asteraceae family and the genus Eupatorium, have high biological potential and are used in folk medicine to treat various diseases. This review article presents the main phytochemical and biological characteristics of the Asteraceae family and the genus Eupatorium s.l., whose antimicrobial activity is promising, especially antibacterial and antifungal activity. The current review was achieved using an organized search of the scientific data published on antimicrobial activity and phytochemical of the species of the genus Eupatorium using various databases, including PubMed, ScienceDirect, Scopus, Scielo, SciFinder and Google Scholar. The species of Eupatorium are rich in terpenes, phytosterols and sesquiterpene lactones, the latter being chemotaxonomic markers of the group, with broad anticancer, antiplasmodial and antimicrobial activity, making them promising for the development of new drugs. Various species of Eupatorium seems to hold great potential for in-depth investigation for antimicrobial activities. Many species have broad folk use, with scientific confirmation of its antimicrobial properties making these plants potential sources of safer and more effective treatments.

The present study aimed to evaluate the antifungal activities of Eupatorium adenophorum against four strains of wood‐decaying fungi, including Inonotus hispida, Inonotus obliquus, and Inonotus cuticularis. Bioguided isolation of the methanol extract of E. adenophorum by silica gel column chromatography and high‐performance liquid chromatography afforded six cadinane‐type sesquiterpenes. Their structures were identified by nuclear magnetic resonance and MS analyses. According to the antifungal results, the inhibition rate of the compound was between 59.85 % and 77.98 % at a concentration of 200 μg/mL. The EC50 values ranged from 74.5 to 187.4 μg/mL.
