“…The bactericidal activity of T. satureioides essential oil may be attributed to the presence of high concentrations of borneol and thymol. Thymol is an oxygenated monoterpene well known with its antimicrobial potential [28,29] which results from its ability to induce structural and functional alterations in the cytoplasmic membrane [30]. In fact, thymol affects membrane permeability and results in the release of K + However, it is difficult to attribute the antimicrobial activity of essential oil, characterized by a complex mixture, to a single or particular constituent.…”

Objective: Thymus satureioides is a well-known aromatic perennial shrub widely used throughout the Mediterranean basin as a culinary herb, in traditional medicine for the treatment of a variety of diseases, and as a natural preservative ingredient in the food industry. The aim of this study was to analyze the chemical composition of T. Satureioides essential oil and to assess its antibacterial and antioxidant activities.Methods: The chemical composition of the essential oil was investigated by Gas chromatography-mass spectrometry (GC-MS). The essential oil was evaluated for its antibacterial activity against Gram-positive and Gram-negative bacteria using agar diffusion method and macro-broth dilution. The antioxidant activity was tested by three different methods, namely DPPH free radical scavenging, β-carotene/linoleic acid and TBARS assays.Results: Thirty compounds were identified, representing 85.52% of the total composition of this essential oil. Borneol (26.45%) and thymol (11.24%) were the major components. The oil had a bactericidal activity against all tested bacteria, with the exception of Pseudomonas aeruginosa. In addition, the T. satureioides essential oil revealed strong antioxidant activity in all conducted assays.Conclusion: The findings suggest that essential oil of T. satureioides may be used as an alternative to synthetic antibiotics and antioxidants.

“…They have reduced molecular weight and can be obtained by steam distillation, hydrodistillation liquid-solvent extraction or supercritical fluid extraction. [4,6] The last family include the Baccharis genus from Asteroideae subfamily, which have different species characterized as perennial shrubs, subshrubs and small trees, with height between 50 cm and 4 m, popularly named in Brazil as 'carqueja' and 'vassoura'. [4,5] Brazil have high floristic diversity and many botanical families have been described by essential oil extraction, such as Myrtaceae, Lauraceae, Lamiaceae and Asteraceae families.…”

This is the first time that composition, antimicrobial potential and antioxidant ability of essential oil from the leaves of Baccharis oreophila are reported. Essential oil was obtained by hydrodistillation and analyzed by GC/MS. Antimicrobial potential was evaluated by diffusion disk and broth microdilution methods. ABTS * + , DPPH * and FRAP methods were employed for antioxidant activity evaluation. Essential oil yield was 0.47 %. Sixty-five compounds were identified, representing 88.53 % of the total essential oil, which showed to be rich in oxygenated (37.88 %) and hydrocarbons sesquiterpenes (34.84 %). The main constituents were khusimone (16.37 %) and spathulenol (16.12 %). Antimicrobial activity was verified against S. aureus (10.33 � 0.5 mm, MIC: 1250 μg mL À 1 ) and C. albicans (8.66 � 0.5 mm, MIC: > 2500 μg mL *1 ). Antioxidant ability was evidenced by FRAP (4.09 μmol FeSO 4 E mL À 1 ), ABTS * + (1.45 μmol TE mL À 1 ) and DPPH * (1.04 μmol TE mL À 1 ) scavenging capacity. Results showed that this essential oil has interesting biological potential, encouraging further investigations especially in relation to action mechanisms of antimicrobial and antioxidant activity.

“…In view of the problems with the current fumigants, there is a global interest in generating alternative strategies. There are numerous studies describing essential oils (EOs) and their components as potential insecticides (Pérez et al, 2010;Caballero-Gallardo et al, 2011;Kurdelas et al, 2012). This insecticidal activity has been evaluated against the maize weevil.…”

Essential oils (EOs) and individual compounds act as fumigants against insects found in stored products. In fumigant assays, Sitophilus zeamais Motschulsky adults were treated with essential oils derived from Aphyllocladus decussatus Hieron, Aloysia polystachya Griseb, Minthostachys verticillata Griseb Epling and Tagetes minuta L , which are rich in ketones and their major components: α-thujone, R-carvone, S-carvone, (-) menthone, R (+) pulegone and E-Z-ocimenone. M. verticillata oil was the most toxic ( LC 50 : 116.6 µl /L air) characterized by a high percentage of menthone (40.1%) and pulegone (43.7%). All ketones showed insecticidal activity against S. zeamais. However, pulegone (LC 50 : 11.8 µl/L air), R-carvone (LC 50 : 17.5 µl/L air), S-carvone (LC 50 : 28.1 µl/L air) and E-Z-ocimenone (LC 50 : 42.3 µl/L air) were the most toxic. These ketones are α,b-unsaturated carbonyl. This feature could play a fundamental role in the increase of insecticidal activity against S. zeamais.
