Hyptis suaveolens (L.) Poit is one of the species Lamiaceae family (Labiatae), is an aromatic plant and can produce essential oils. Essential oils of these plants can be utilized as antimicrobials. The chemical components contained in the essential oils in the same plant may vary as they are influenced by several factors, including the growth stage. Essential oils can be obtained by hydrodestilation and their components are analyzed using gas chromatography-mass spectrometry (GC-MS). The essential oil components are then compared between those found in young leaves and adult leaves. The results of analysis and identification showed that in young leaves there are 50 components while in adult leaves there are only 37 components. The main components of young leaves were ?-caryophyllene (34.65%), germacrene-D (10.32%), ?-bergamotene (6.56%), ?-copaene (5.94%) and rimuene (6.46%), Are ?-caryophyllene (23.53%), germacrene-D (9.52%), ?-elemente (6.53%) and rimuene (13.19%). The components of ?-bergamotene and ?-copaene are not found in adult leaves.

This study focused on characterization of the chemical components of an aromatherapy recipe. The formulation consisted of four blended essential oils; rosemary oil, eucalyptus oil, pine oil and lime oil (volume ratio 6: 2: 1: 1). The single and combination essential oils were identified by gas chromatography-mass spectrometry (GC-MS). The analysis of GC-MS data revealed that several components exist in the mixture. The five most important components of the blended essential oils were 1,8-cineole (35.6 %), α-pinene (11.1 %), limonene (9.6 %), camphor (8.4 %), and camphene (6.6 %). The main components of rosemary oil were 1,8-cineole (37.3 %), α-pinene (19.3 %), camphor (14.7 %), camphene (8.8 %), and β-pinene (5.5 %); of eucalyptus oil 1,8-cineole (82.6 %) followed by limonene (7.4 %), o-cymene (4.3 %), γ-terpinene (2.7 %), and α-pinene (1.5 %); of pine oil terpinolene (26.7 %), α-terpineol (20.50 %), 1-terpineol (10.8 %), α-pinene (6.0 %), and γ-terpineol (5.3 %); and of lime oil limonene (62.9 %), γ-terpinene (11.5 %), α-terpineol (7.6 %), terpinolene (6.0 %), and α-terpinene (2.8 %). The present study provided a theoretical basis for the potential application of blended essential oils to be used as an aromatherapy essential oil recipe. GC-MS serves as a suitable and reliable method for the quality control of the chemical markers.

In this study, the antitrypanosomal action of Lavandula angustifolia Mill. (Lavender), Matricaria chamomilla L. (chamomile) and Ocimum basilicum L. (Basil) essential oils was investigated against Trypanosoma evansi. The Gas Chromatography/Mass Spectrometry (GC/MS) was used to analyze these essential oils and identifying their chemical components. The main components present in lavender oil were 1,8-cineole (88.02%) and camphor (8.09%). In chamomile oil, bisabolol oxide (43.81%), cis-α-farnesene (17.79%) and bisabolone oxide (7.71%) were found to be the most predominant components. Basil oil is principally composed of benzene, 1-methoxy-4-(2-propenyl) (52.68%), L-linalool (29.46%) and 1, 8-cineole (9.46%). In vitro results revealed that all the tested oils exhibited notable trypanocidal action and inhibited the growth of T. evansi. The minimum antitrypanosomal activity was determined by chamomile oil and the strongest was determined by lavender oil. These findings suggest that the tested essential oils could be investigated in future studies for the treatment of T. evansi.

Background: Aristolochia triangularis Cham., popularly known as the "cipó-mil-homens", "angelicó" and "ypê-mi", is applied for the treatment of wounds, skin diseases (6,7), digestive and circulatory system diseases as an antipyretic and for malaria fever. Objective: In this work we investigated the chemical composition, the antimicrobial and antimycobacterial activities of the essential oils (EOs) extracted from A. triangularis fresh stems and leaves collected in Southern Brazil. Methods: Fresh stems and fresh leaves of Aristolochia triangularis Cham. were separately subjected to hydrodistillation using a Clevenger-type apparatus. The chemical composition of the essential oils (EOs) were analyzed by gas chromatography/mass spectrometry (GC/MS). The oil samples were evaluated for their antimycobacterial, antibacterial and antifungal activities against twenty-four microorganisms. Results: Hydrodistillation of fresh stems and leaves of A. triangularis resulted in 0.16% (w/w) and 0.37% (w/w) respectively of light-yellow oils. Germacrene D is found in 13.2 - 13.5% in both EOs. The constituent most abundant in the stems EO (19.18%) was the oxygenated diterpene ent-Kaur-16-en-19-al (10), along with E-nerolidol (17.89%). The main constituents of the leaves EO were bicyclogermacrene (24.79%), β-elemene (11.30%), E-caryophyllene (10.40%) and germacrene A (9.42%), in addition to the previously mentioned germacrene D. The stems and leaves EOs showed capacity to inhibit the Gram-negative Enterobacter aerogenes and the stems EO capacity to inhibit Staphylococcus aureus, with MIC values of 31.2 µg/mL. S. aureus was moderately sensitive to leaves EO, while stems EO displayed moderate activity against Enterococcus faecalis and Salmonella typhimurium (MIC values of 62.5 µg/mL). Candida glabrata was highly susceptible to both EOs (MIC values < 3.9 µg/mL). The EOs showed moderate potential to inhibit the growth of Cryptococcus gatti and Cryptococcus neoformans (MICs of 62.5 μg/mL). Conclusion: The A. triangularis essential oils from stems and leaves displayed capacity to inhibit Enterobacter aerogenes (MIC values of 31.2 µg/mL) and high antifungal effect against Candida glabrata (MIC values of <3.9 µg/mL). Mycobacterium massiliense and M. abscessus were susceptible to the leaves EO, with MICs of 39.06 μg/mL. These results showed the A. triangularis essential oils potential as antifungal and antimycobacterial to be used in the development of new antibiotic.

We report an analysis of chemical components of essential oils from barks of Ceylon cinnamon and cloves of Syzygium aromaticum and an investigation of their antibacterial activity. The components of oils were determined by using Gas Chromatography/Mass Spectrometry (GC-MS) analysis, and the antimicrobial activity was assessed by the disk diffusion test. The synergic effect of essential oils mixture (cinnamon oil and clove oil) was evaluated. Antimicrobial properties were conferred to cellulosic fibers through microencapsulation using citric acid as a green binding agent. Essential oil mixture was encapsulated by coacervation using chitosan as a wall material and sodium hydroxide as a hardening agent. The diameter of the produced microcapsules varies between 12 and 48 μm. Attachment of the produced microcapsules onto cotton fabrics surface was confirmed by Attenuated Total Reflectance-Fourier Transformed Infrared (ATR-FTIR) spectroscopy, optical microscopy and Scanning Electron Microscopy (SEM) analysis. The results show that microcapsules were successfully attached on cotton fabric surfaces, imparting antibacterial activity without significantly affecting their properties. The finished cotton fabrics exhibited good mechanical properties and wettability.

The chemical composition of the essential oils obtained by hydrodistillation from the aerial parts of Thymus serpyllum and Thymus serpyllum‘Aureus’ has been investigated by gas chromatography-mass spectrometry (GC-MS). Forty-seven compounds (99.67% of the total oil) wereidentified in the essential oil of T. serpyllum. The main components found in the oil were carvacrol (37.49%), -terpinene (10.79%), -caryophyllene (6.51%), p-cymene (6.06%), (E)--ocimene (4.63%) and -bisabolene (4.51%). Similarly, carvacrol (44.93%), -terpinene(10.08%), p-cymene (7.39%) and -caryophyllene (6.77%) dominated in the oil of T. serpyllum ‘Aureus’. A total of forty three compounds wereidentified in this oil, representing 99.49% of the total oil content. On the basis of the obtained data it was proved that the content of 1-octen-3-ol,eucalyptol, (Z)--ocimene, (E)--ocimene, -terpinene, carvacrol methyl ether, germacrene D and -bisabolene was significantly higher for T.serpyllum while T. serpyllum ‘Aureus’ was characterized by a significantly higher content of 3-octanone, 3-octanol, p-cymene, borneol andcarvacrol. The isolated essential oils were evaluated for their antimicrobial activity against nine reference strains (Escherichia coli, Staphylococcusaureus, Staphylococcus epidermidis, Streptococcus agalactiae, Enterococcus faecalis, Bacillus cereus, Micrococcus luteus, Proteus vulgaris and Candidaalbicans) by the microdilution technique. Based on this test, the minimum inhibitory concentrations (MIC) of essential oil were calculated. Thevolatile oil obtained from T. serpyllum showed the highest antimicrobial activity relative to the strain of E. coli (MIC=0.025 μL/mL) and to theyeast C. albicans (MIC=0.05 μL/mL). Similarly, a significant antimicrobial activity exhibited T. serpyllum ‘Aureus’ essential oil, although the MICvalues obtained in that case for E. coli and C. albicans strains were twice as high and were respectively 0.05 μL/mL and 0.1 μL/mL.
