“…The GC/MS analyses indicated that (E)-anethole constitutes over 90% of the total composition of the tested essential oil. Our findings align with the existing literature, which consistently identifies (E)-anethole as the predominant component, typically comprising between 70% and 94% of the oil s composition [34][35][36][37]. Besides this phenylpropanoid, estragole was detected with a percentage value of 4.8%.…”

Illicium verum, commonly known as star anise, represents one of the notable botanical species and is recognized for its rich reservoir of diverse bioactive compounds. Beyond its culinary application as a spice, this plant has been extensively utilized in traditional medicine. Given the contemporary emphasis on incorporating natural resources into food production, particularly essential oils, to enhance sensory attributes and extend shelf life, our study seeks to elucidate the chemical composition and evaluate the antibacterial (in vitro, in situ) and insecticidal properties of Illicium verum essential oil (IVEO). Also, microbiological analyses of pumpkin sous vide treated with IVEO after inoculation of Salmonella enterica were evaluated after 1 and 7 days of study. GC/MS analysis revealed a significantly high amount of (E)-anethole (88.4%) in the investigated EO. The disc diffusion method shows that the antibacterial activity of the IVEO ranged from 5.33 (Streptococcus constellatus) to 10.33 mm (Citrobacter freundii). The lowest minimal inhibition concentration was found against E. coli and the minimum biofilm inhibition concertation was found against S. enterica. In the vapor phase, the best antimicrobial activity was found against E. coli in the pears model and against S. sonei in the beetroot model. The application of the sous vide method in combination with IVEO application decreased the number of microbial counts and eliminated the growth of S. enterica. The most isolated microbiota identified from the sous vide pumpkin were Bacillus amyloliquefaciens, B. cereus, B. licheniformis, and Ralstonia picketii. Modifications to the protein composition of biofilm-forming bacteria S. enterica were suggested by the MALDI TOF MS instigations. The IVEO showed insecticidal potential against Harmonia axyridis. Thanks to the properties of IVEO, our results suggest it can be used in the food industry as a natural supplement to extend the shelf life of foods and as a natural insecticide.

“…It has been claimed that aniseed extract has antifungal qualities because of its anethole concentration [41,42]. Additionally, aniseed fractions in diethyl ether showed substantial antibiotic activity against MRSA, Pseudomonas aeruginosa, and Acinetobacter baumannii [43,44]. Additionally, anethole had far greater activity than other key components including anisyl alcohol, anisyl aldehyde, and anisyl acetone [45].…”

“…Moreover, it has been shown that aniseed's non-polar components produce antimicrobial metabolites. Terpenoids and isoprenoids, which make up the bulk of plant essential oils and are the most varied class of biogenic volatile organic chemicals in plants [47], are greatly influenced by environmental and biotic variables, including light, temperature, soil water, and fertility [44].…”

Chemical Constituents, Antioxidant Potential, and Antimicrobial Efficacy of Pimpinella anisum Extracts against Multidrug-Resistant Bacteria

et al. 2023

Aniseeds (Pimpinella anisum) have gained increasing attention for their nutritional and health benefits. Aniseed extracts are known to contain a range of compounds, including flavonoids, terpenes, and essential oils. These compounds have antimicrobial properties, meaning they can help inhibit the growth of nasty bacteria and other microbes. The purpose of this study was to determine if aniseed extracts have potential antioxidant, phytochemical, and antimicrobial properties against multidrug-resistant (MDR) bacteria. A disc diffusion test was conducted in vitro to test the aniseed methanolic extract’s antibacterial activity. The MIC, MBC, and inhibition zone diameters measure the minimum inhibitory concentration, minimum bactericidal concentration, and size of the zone developed when the extract is placed on a bacterial culture, respectively. HPLC and GC/MS are analytical techniques used for identifying the phenolics and chemical constituents in the extract. DPPH, ABTS, and iron-reducing power assays were performed to evaluate the total antioxidant capacity of the extract. Using HPLC, oxygenated monoterpenes represented the majority of the aniseed content, mainly estragole, cis-anethole, and trans-anethole at 4422.39, 3150.11, and 2312.11 (g/g), respectively. All of the examined bacteria are very sensitive to aniseed’s antibacterial effects. It is thought that aniseed’s antibacterial activity could be attributed to the presence of phenolic compounds which include catechins, methyl gallates, caffeic acid, and syringic acids. According to the GC analysis, several flavonoids were detected, including catechin, isochiapin, and trans-ferulic acid, as well as quercitin rhamnose, kaempferol-O-rutinoside, gibberellic acid, and hexadecadienoic acid. Upon quantification of the most abundant estragole, we found that estragole recovery was sufficient for proving its antimicrobial activity against MDR bacteria. Utilizing three methods, the extract demonstrated strong antioxidant activity. Aniseed extract clearly inhibited MDR bacterial isolates, indicating its potential use as an anti-virulence strategy. It is assumed that polyphenolic acids and flavonoids are responsible for this activity. Trans-anethole and estragole were aniseed chemotypes. Aniseed extracts showed higher antioxidant activity than vitamin C. Future investigations into the compatibility and synergism of aniseed phenolic compounds with commercial antibacterial treatments may also show them to be promising options.

“…Overall, the antibacterial activity shown by gram-negative bacteria was less than that of gram-positive bacteria. The resistance shown by gram-negative bacteria was due to the presence of impenetrable cell wall [28][29]. This is also important from medicinal point of view because antibacterial compounds which are normally used in therapy are active mainly against Gram-positive bacteria [30].…”

This research work aims to assess antibacterial potential of five liverwort species that have been collected from District Bagh Azad Jammu and Kashmir. For this purpose, two bacterial strains including Achromobacter xylosoxidans (Gram- negative) and Bacillus licheniformis (Gram- positive) were used by following disc diffusion method. The extract of the species was prepared in ethanol, methanol and water. The results showed that ethanol and methanol extracts of all liverworts have stronger and broader spectrum for the zone of inhibition against both bacteria. Among all investigated species, Marchantia emarginata and Pellia epiphylla showed most promising results, whereas lowest activity was shown by Plagiochasma rupestre. In aqueous extract, only Marchantia paleacea and Plageochasma rupestre showed positive results. In general, resistance shown by Gram-positive strains was superior to Gram-negative strains. This study proved that the investigated liverwort species possess strong defensive mechanism against bacteria and can be used to prepare novel antibiotics.
