“…Aromatic and medicinal plants are a source of several essential oils, and well-known since ancient times for numerous therapeutic properties [1,2]. Lavandula officinalis (Lavender) belongs to the Lamiaceae family specifically in the genus of Lavandula which consists of about 28 species [3,4]. Lavender is a shrub of height 20 to 80 cm that grows in sunny and mountainous areas of the Mediterranean, especially in the Rif, middle and high Atlas.…”

The purpose of this study was to determine the chemical composition of the essential oil of Lavandula officinalis from Morocco using the GC-MS technique and assess the antibacterial effects against seven pathogenic bacteria strains isolated from the food origins of Salmonella infantis, Salmonella kentucky, Salmonella newport, three serotypes of Escherichia coli (O114H8K11, O127K88ac, O127H40K11) and Klebsiella. Tests of sensitivity were carried out on a solid surface using the Disc Diffusion Method. Results showed that E. coli and S.newport were sensitive to Lavandula officinalis essential oil. Minimum inhibitory concentrations (MIC) were determined using the method of agar dilution. The antibacterial results showed that four strains (three serotypes of E. coli, and S. newport) were remarkedly sensitive to Lavandula officinalis essential oil, giving MIC values of 88.7 µg/mL and 177.5 µg/mL. The molecular docking of the main oil products with the E. coli target protein 1VLY, showed that eucalyptol and linalyl acetate bind efficiently with the active site of the target protein. In particular, eucalyptol showed a higher activity than gentamicin used as positive control with a binding energy of −5.72 kcal/mol and −5.55 kcal/mol, respectively.

“…and phenolic diterpenes [25] with camphor being one the most important volatile compounds [26]. Camphor, which has a characteristic camphoraceous odour and is used commercially as a moth repellent [27], is credited with specific bioactive effects such as anesthetic effect [28], pesticidal and insecticidal properties [29], antimicrobial activity [30] or mild expectorant activity [31]. In addition, it has a precursor borneol, another aromatic compound of rosemary, which is transformed into camphor and may cause the camphor content of rosemary to increase over time [32,33].…”

This study determined the effect of three concentrations (R1: high, R2: medium and R3: low) of rosemary added to dry-cured ham slices vacuum packaged. pH and the colour parameters were evaluated at 0, 7, 14, 28 and 60 days of storage; visual appearance, odour, flavour and camphor content were assessed at days 7, 14, 28 and 60. The rosemary concentration changed the colour parameters, significantly altering the visual appearance (p < 0.001 at 7 and 14 days; p < 0.5 at day 28), but did not affect the pH, neither odour nor flavour. Nevertheless, significant differences were found with the time on R1 and R2 in odour (p < 0.01 and p < 0.001, respectively) and in flavour (p < 0.001). Camphor content was similar in all samples but changed over the time in R1 (p < 0.001) and R2 (p < 0.01). In conclusion, despite the differences observed, it is evident that the addition of this spice was to the liking of the panellists, in any of the concentrations used.

“…This finding indicates that β-pinene and its derivatives have significant research and application values in microbial action. Similarly, camphene, a minor constituent of many essential oils derived from plants, such as turpentine oil, cypress oil, citronella oil, etc., can be produced by the isomerization reaction of α-pinene. – It has been well-demonstrated that camphene possesses a wide range of pharmacological activities, including antimicrobial, antitumor, antihyperlipidemia, and insecticidal activities, so that it has been widely applied in the field of agriculture, forestry, and pharmaceutical. – Therefore, camphene is an ideal resource for developing novel QASs.…”

A series of novel quaternary ammonium salts (QASs) (4a–4n) comprising a camphene moiety were synthesized for the first time. Fourteen examples were prepared from camphene through Prins reaction, halogenation, and quaternarization, successively. The structures of the synthesized QASs were analyzed by Fourier transform infrared spectroscopy, 1H NMR, 13C NMR and high-resolution mass spectrometry. Surface-active properties, emulsifying abilities, and foaming properties of the investigated compounds were then studied. The antimicrobial activities of these QASs against Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis), Gram-negative bacteria (Escherichia coli and Klebsiella pneumoniae), and fungi species (Candida albicans, Candida tropicalis, and Aspergillus niger) were determined by the microdilution method. The results showed that the chemical structural factors, including types of substitutes and alkyl chain length, might be correlated with the lipid–water partition coefficient (cLog P), which played a critical role in the antimicrobial process. Compounds with alkyl chain lengths (N) in the range of 10–14 were relatively more active, while compounds bearing pyridinium, benzyl, methylimidazolium groups, or varied alkyl chain lengths (N < 5 and N > 16) were almost inactive. Compound 4k possessing a dodecyl group exhibited the most effective and broad-spectrum antimicrobial activity against almost all tested bacteria and fungi with the minimal inhibitory concentration values ranging from 0.24 to 0.98 μg/mL.
