Chemical Characterization and Antimicrobial Activity of Essential Oils of Mint (Mentha spicata L.) and Surinam Cherry (Eugenia uniflora L.)

The effect of solvent polarity (methanol and pentane) on the chemical composition of hydrodistilled essential oils (EO’s) ofLippia graveolensH.B.K. (MXO) andOriganum vulgareL. (EUO) was studied by GC-MS. Composition of modified starch microencapsulated EO’s was conducted by headspace-solid-phase microextraction (HS-SPME). The antimicrobial activity of free and microencapsulated EO’s was evaluated. They were tested againstSalmonellasp.,Brochothrix thermosphacta,Pseudomonas fragi, Lactobacillus plantarum, andMicrococcus luteus. Thymol and carvacrol were among the main components of EO’s and their free and microencapsulated inhibitory activity was tested againstM. luteus, showing an additive combined effect. Chemical composition of EO’s varied according to the solvent used for GC analysis and to volatile fraction as evaluated by HS-SPME. Thymol (both solvents) was the main component in essential oil of MXO, while carvacrol was the main component of the volatile fraction. EUO showedα-pinene (methanol) andγ-terpinene (pentane) as major constituents, the latter being the main component of the volatile fraction. EO’s showed good stability after 3 months storage at 4°C, where antimicrobial activity of microencapsulated EO’s remained the same, while free EO’s decreased 41% (MXO) and 67% (EUO) from initial activity. Microencapsulation retains most antimicrobial activity and improves stability of EO’s from oregano.

Mentha L., recognized as a medical and aromatic plant, is a general name affiliated to mint species and belongs to Labiatae family. Some species are used as fresh vegetables in the Turkish kitchen and they can also be used in salads. In addition, some species have been used as a spice in food. In this study, chemical composition and antimicrobial activity towards some pathogenics (gram + and gram -) microorganisms of the essential oils Mentha spicata L. subsp. tomentosa (Briq.) Harley, Mentha pulegium L. grown under West Anatolian ecological conditions were investigated. Extractions were carried out with Clevenger apparatus and essential oil composition was determined by Gas Chromatography-Mass Spectrometry (GC-MS). Microorganisms used for the antimicrobial studies were Methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus aureus ATCC 6538, Pseudomonas aeruginosa, Enterecoccus faecium DSM 13590, Escherichia coli Q157:H7 and Bacillus cereus CCM99. As a result, M. pulegium and M. spicata subsp. tomentosa were found to be rich in piperitenone oxide: 72.77% and 28.84%, respectively. Each of the oils was found to possess antimicrobial properties against test microorganisms. Essential oils obtained from Mentha species give positive effect on all microorganisms.

Antibacterial And Antifungal

Many Lamiaceae species are consumed in the Lebanese cuisine as food or condiment and are largely used in the traditional medicine of Lebanon to treat various diseases, including microbial infections. In this article we report the traditional medicinal uses of eleven Lamiaceae species:Coridothymus capitatusL.,Lavandula stoechasL.,Lavandula angustifoliaMill.,Mentha spicataL. subsp.condensata,Origanum syriacumL.,Rosmarinus officinalis,Salvia fruticosaMiller.,Satureja cuneifoliaTen.,Satureja thymbraL.,Thymbra spicataL., andVitex agnus-castusL. and study the chemical composition and antimicrobial activity of their essential oils (EOs). Our survey showed that Lamiaceae species are mainly used against gastrointestinal disorders and microbial infections. Chemical analysis of the EOs obtained from these plants allowed us to identify seventy-five compounds describing more than 90% of the relative composition of each EO. Essential oils with high amounts of thymol and carvacrol possessed the strongest antimicrobial activity. As expected, these two compounds demonstrated an interesting antifungal efficacy against the filamentous fungusT. rubrum. Our results confirmed that some of the Lamiaceae species used in Lebanon ethnopharmacological practices as antimicrobial agents do possess antibacterial and antifungal potential consistent with their use in alternative or complementary medicine.

Abstract The essential oil (EO) composition of leaves of Campomanesia aurea was analyzed by GC-MS. The plant was collected in April (EOA) and October (EOO) in São Francisco de Assis/RS. The essential oils were obtained by hydrodistillation in a modified Clevenger apparatus. The yields were 4.44% in April, and 6.15%, in October. Thirty-one compounds were identified in EOA, accounting for 96.87% of the total, and twenty-eight compounds were identified in EOO, accounting for 99.46% of the total. For EOA, the major identified monoterpene was p-cymene (8.33%) and the major identified sesquiterpene was α-cadinol (10.72%), while regarding EOO the major identified monoterpene was repeatedly Terpinolene (3.43%), whereas the major identified sesquiterpene was α-cadinol (12.79%). The antibacterial activity of the essential oil was evaluated against the three Listeria monocytogenes from the American Type Culture Collection (strains ATCC 7644, 19114 and 13932). The essential oil showed a MIC of 10 mg/mL against the strains ATCC 7644 and 19114, with bacteriostatic effect of 20 mg/mL and a MIC of 20 mg/mL for ATCC 13932. Regarding the antibiofilm activity, o EOO showed the best results with an inhibition of 90% in the sessile growth with an applied concentration of 4.0 mg/mL.
