“…Overall, the essential oil yields of O. basilicum in the present study were comparable to those of Verma et al, 27 and Hussain et al, 10 . Those obtained from O. canum in this study were much higher than those reported by Yayi et al, 18 and Verma et al, 27 (0.1-0.30 %) for the same species, but comparable to those of Burkina Faso and Comoro Islands (1.0-2.2 %) [28][29][30] . O. gratissimum contained higher oil yields than those reported by Kpoviessi et 5,7,27,32 .…”

“…The MIC/ MBC values at 19h were 0.50/1.25 μL/mL against L. monocytogenes, and 1.0/1.25 μL/mL against S. Typhimurium. Previously, O. canum oil was found to be effective against a wide range of bacteria including L. monocytogenes, L. ivanovii, L. innocua and S. enterica using paper disc diffusion assay 7,29 . In this study, the highest antibacterial activity corresponded to the highest content in carvacrol (30.8 %) present in oil of O. canum harvested at 19h.…”

Abstract:The chemical composition of essential oils obtained by hydrodistillation from aerial parts of Ocimum basilicum, Ocimum canum and Ocimum gratissimum from Benin as affected by harvesting time, were analyzed by GC-FID (Gas chromatography-Flame ionization detector) and GC-MS (Gas chromatographyMass spectrometry). Based on the composition analysis, major components were as follows: estragol (43.0 -44.7 %) and linalool (24.6 -29.8 %) in O. basilicum oils; carvacrol (12.0 -30.8 %) and p-cymene (19.5 -26.2 %) in O. canum oils; thymol (28.3-37.7 %) and γ-terpinene (12.5-19.3 %) in O. gratissimum oils. Disc diffusion and broth microdilution assays were used to evaluate the antibacterial activity of essential oils and their main components against two foodborne bacteria, Listeria monocytogenes and Salmonella enterica serotype Typhimurium. The tested oils and their components exhibited notable antimicrobial activities against L. monocytogenes and S. Typhimurium. The O. canum and O. gratissimum oils collected at 7h and 19h showed significant higher activities against L. monocytogenes and S. Typhimurium (MICs and MBCs 0.34 -2.5 μL/ mL) (p < 0.05), whereas O. basilicum showed lower activity (MICs and MBCs 2.0 -8.0 μL/mL) at any daytime of harvest, the weakest being at 19h (MIC and MBC 12.0 -32.0 μL/mL). The daytime of harvest can influence the composition of oils and their activities on bacteria.

“…A recent study has suggested an antagonism of the essential oils with high percentages of p-cymene and phenolic monoterpenes (thymol and carvacrol), reducing the antimicrobial activity of the essential oil (32). This may explain in part the higher activity of thymol and carvacrol when evaluated separately.…”

Dental caries and periodontal disease are associated with oral pathogens. Several plant derivatives have been evaluated with respect to their antimicrobial effects against such pathogenic microorganisms. Lippia sidoides Cham (Verbenaceae), popularly known as "Alecrimpimenta" is a typical shrub commonly found in the Northeast of Brazil. Many plant species belonging to the genus Lippia yield very fragrant essential oils of potential economic value which are used by the industry for the commercial production of perfumes, creams, lotions, and deodorants. Since the leaves of L. sidoides are also extensively used in popular medicine for the treatment of skin wounds and cuts, the objective of the present study was to evaluate the composition and antimicrobial activity of L. sidoides essential oil. The essential oil was obtained by hydro-distillation and analyzed by GC-MS. Twelve compounds were characterized, having as major constituents thymol (56.7%) and carvacrol (16.7%). The antimicrobial activity of the oil and the major components was tested against cariogenic bacterial species of the genus Streptococcus as well as Candida albicans using the broth dilution and disk diffusion assays. The essential oil and its major components thymol and carvacrol exhibited potent antimicrobial activity against the organisms tested with minimum inhibitory concentrations ranging from 0.625 to 10.0 mg/mL. The most sensitive microorganisms were C. albicans and Streptococcus mutans. The essential oil of L. sidoides and its major components exert promising antimicrobial effects against oral pathogens and suggest its likely usefulness to combat oral microbial growth.

“…All tests were carried out in quadruplicate and the results are expressed as mean ± standard deviation. Microdilution broth susceptibility assays were employed for determination of minimum inhibitory concentrations (MIC) of the essential oil [36]. Amoxicilline-clavulanate and fluconazole served as reference antimicrobials.…”

Thymus longicaulis C. Presl is a small aromatic perennial herb used as a traditional remedy for cold, flu and cough. Composition of the essential oil of T. longicaulis from Croatia and its in vitro antimicrobial activity against the most common respiratory pathogens were evaluated. The yield of essential oil obtained by hydrodistillation from aerial plant parts was 1.2%. According to the GC-MS analysis, a total of forty one compounds (99%) were identified. Thymol (46.3%), γ-terpinene (16.2%), thymyl methyl ether (11.4%), and p-cymene (9.4%) were the main components. Antimicrobial activity of the essential oil against six clinically isolated bacterial and yeast strains was determined using standard disc agar diffusion method and microdilution broth assay. The essential oil exhibited antimicrobial activity towards all tested respiratory pathogens. The most sensitive strains were Haemophilus influenzae and Streptococcus pneumoniae(MIC=0.78 mg/mL), while Staphylococcus aureus was the most resistant (MIC>25.00 mg/mL). Our results indicate that T. longicaulis essential oil could be effective against clinically relevant respiratory pathogens which have the ability to develop resistance to antimicrobial drugs.
