“…Terpene and sesquiterpene hydrocarbons, oxygenated or cyclic, are the main classes of compounds present in EOs, followed by aldehydes, ketones, alcohols, acids and esters [25]. In particular, thanks to their interesting physicochemical characteristics, Lamiaceae EOs were employed in the industrial and medical research sectors as natural products [26]. EOs obtained from L. angustifolia and R. officinalis grown in different countries such as China, Siria, India, Iran, Romania, Canada, Spain, France and others were investigated and linalool, borneol, linalyl acetate and 1,8-cineole as well as camphor, camphene and α-pinene resulted as predominant compounds, although in different proportions according to the vegetative stage and climatic conditions of the origin area [27,28].…”

In this work, essential oils (EOs) and hydrolates (Hys) of Rosmarinus officinalis L. and Lavandula angustifolia Mill., grown in Tuscany (Italy), were studied to describe their chemical composition and biological activities. The aromatic profile of the EOs liquid phase was carried out by gas chromatography–mass spectrometry (GC–MS), while the volatile composition of vapor phase EOs and Hys was performed by headspace (HS)/GC–MS. The obtained results show that monoterpene hydrocarbons (71.5% and 89.5%) were the main compounds, followed by oxygenated monoterpenes (26.0% and 10.5%) in the liquid and vapor phase of R. officinalis EO, respectively. The oxygenated monoterpenes were the main components of L. angustifolia EO, reaching 86.9% in the liquid phase and 53.7% in the vapor phase. Regarding Hys, they consisted only of oxygenated monoterpenes, and 1,8-cineole (56.2%) and linalool (42.9%), were the main components of R. officinalis and L. officinalis Hys, respectively. Their cytotoxicity was investigated on an SHSY5Y neuroblastoma cell line by thiazolyl blue tetrazolium bromide (MTT) test, showing a notable effect of the EOs with a time-independent manner of activity and half maximal effective concentration (EC50) values quite similar for the two plant species (from 0.05% to 0.06% v/v for the three time points evaluated). A measurable activity of Hys was also obtained although with higher EC50 values. The antibacterial activity against Escherichia coli ATCC® 25922, Pseudomonas fluorescens ATCC® 13525, Acinetobacter bohemicus DSM 102855 as Gram-negative bacteria and Kocuria marina DSM 16420, Bacillus cereus ATCC® 10876 as Gram-positive bacteria, was evaluated by the agar disk-diffusion method and the VPT (vapor phase test) to determinate the MIC (minimal inhibitory concentration) and the MBC (minimal bactericidal concentration) values. Both EOs possessed a high activity against all the bacterial strains with MIC values ranging from 0.19% to 3.13% v/v. Unlike EOs, Hys did not show an inhibition of the bacterial growth at the tested concentrations. Furthermore, antioxidant power was measured by 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt-based (ABTS•+) and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays, showing a remarkable ability to reduce radicals by both EOs; Hys were slightly less active. The findings highlighted that R. officinalis and L. angustifolia EOs and Hys have a chemical composition rich in bioactive molecules, which can exert different biological activities.

“…Because of their interesting physicochemical characteristics of substantial value, the Lamiaceae essential oils have garnered research and industrial interests for their use as natural products [23]. However, in Tunisia, apart from R. officinalis EO, Lamiaceae EOs production is still weak despite the plants abundance and scientific researches on these EOs bioactivities [14,24,25].…”

Background: Lamiaceae family is one of the most diverse and common plant families in terms of ethnomedicine due to their potential therapeutic effects. The aim of this study is to investigate the correlation between the chemical composition and the antibacterial effect of five essential oils from this family against five reference bacterial strains responsible of nosocomial diseases and foodborne illnesses. Methods: The commercial essential oils of Tunisian Rosmarinus officinalis, Thymus capitatus, Origanum majorana and Salvia officinalis were analyzed by GC/FID and GC-MS. Essential oils were evaluated for their antibacterial activities by disc diffusion and microbroth dilution methods against five reference bacterial strains: Pseudomonas aeruginosa, Escherichia coli, Salmonella enterica, Bacillus subtilis and Staphylococcus aureus. The inhibition zone diameter values and the twenty major compounds of the selected essential oils were subjected to PCA and HCA analysis. Results: Analysis by GC/FID and GC/MS allowed the identification of ninety-one components representing 96.0 to 98.2% of the total oils. The different component contents varied according to the species. The main components were carvacrol, 1,8-cineole, α-thujone, α-terpineol and α-pinene. The PCA and the HCA of the selected essential oil components and the inhibition zone diameter (IZD) values identified four species groups and subgroups. Each essential oils group constituted a chemotype responsible for their bacterial inhibition ability. Thymus capitatus essential oil showed the strongest antibacterial activity with MBC ranging from 0.73 to 2.94 mg mL − 1. Conclusion: Rosmarinus officinalis, Thymus capitatus, Origanum majorana and Salvia officinalis essential oils have shown promising antibacterial activities against reference bacterial strains responsible for nosocomial diseases and foodborne illnesses.

Lamiaceae, a family of flowering plants, have been historically used as culinary herbs, shrubs and medicinal plants. With this study, the volatile organic compounds (VOCs) of the five species of the Lamiaceae family (Thymus cilicicus, Clinopodium nepeta L., Nepeta italica L., Thymbra spicata L. and Ziziphora clinopodioides) that grow in Turkey were identified by the SPME/GC‐FID/MS method. The five species were screened in order to reveal their antibacterial and antioxidant activities. Phenolic compound analyses of five species were performed by using RP‐HPLC with diode array detection. Among the total number of 73 compounds that were identified, α‐pinene (2.2%‐13.8%), β‐pinene (0.3%‐25.9%), p‐cymene (0.7%‐17.9%), γ‐terpinene (0.4%‐22.0%), carvacrol (0.1%‐40.2%), sabinene (1.2%‐34.2%), terpinen‐4‐ol (0.2%‐27.5%), (E)‐β‐caryophyllene (0.1%‐13.8%) and (E)‐β‐farnesene (0.4%‐19.7%) were found to be the most plentiful ones. The minimal inhibitory concentration (MIC) values of the methanol extracts of the five species of the Lamiaceae family were investigated, and the results were in the range of 23‐959 µg/mL; the most pronounced antibacterial activities were determined to be against Mycobacterium smegmatis (23‐291 µg/mL). All of the methanol extracts possessed effective antioxidant capacity (IC50: 1.82‐28.18 μmol/L Trolox/g sample) as estimated from the 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical‐scavenging assays. Additionally, the effect of phenolics, especially benzoic acid (86.27, 27.85, ‐, 13.11, 9.59 mg/g extract, respectively), on the biological properties of the methanol extracts of the five species of the Lamiaceae family, was investigated.
