The aim of the study was to examine the antibiofilm activity of selected essential oils (EO): Lavandula angustifblia (LEO), Melaleuca alternifolia (TTO), Melissa officinalis (MEO) and some of their major constituents: linalool, linalyl acetate, alpha-terpineol, terpinen-4-ol. Biofilms were formed by Staphylococcus aureus ATCC 29213 and Escherichia coli NCTC 8196 on the surface of medical biomat...

Essential oils, commonly known as etheric oils (essential oil, volatile oil), are produced by plants and can be obtained from the roots, stems, leaves, flowers of plants. This study aims to determine chemical components kaffir lime (Citrus hystix) essential ylang (Cananga ordorata), patchouli oil (Pogostemon cablin benth) farmers refiners in Lembang, West Java. The composition this was analyzed...

Achillea millefolium L. is a member of the Asteraceae family and has been used in folk medicine in many countries. In this study, 19 compounds in A. millefolium essential oil (AM-EO) have been identified; the major components are artemisia ketone (14.92%), camphor (11.64%), linalyl acetate (11.51%) and 1,8-cineole (10.15%). AM-EO can suppress the inflammatory responses of lipopolysaccharides (L...

This study was designed to examine for the first time the antimicrobial and antioxidant activities of essential oils and organic extracts of Tunisian Citrus aurantium. Essential oils extracted by hydrodistillation from the peels, leaves and flowers were characterized by GC–MS. It results in the identification of three chemotypes: limonene (87,02 %), linalyl acetate (53,76 %) and linalool (39,74...

Tuta absoluta is a pest of importance: quick to disperse and difficult control due the cases resistance insecticide active ingredients. Thus, studies using essential oils (EOs) search for new molecules should be intensified. The objective present study was evaluate toxicity EOs from Citrus aurantifolia (lime), aurantium (petitgrain) bergamia (bergamot) its major compounds against T. in topical ...

Thyme (Thymus vulgaris L.) is a commonly used flavoring agent and medicinal herb. Several chemotypes of thyme, based on essential oil compositions, have been established, including (1) linalool; (2) borneol; (3) geraniol; (4) sabinene hydrate; (5) thymol; (6) carvacrol, as well as a number of multiple-component chemotypes. In this work, two different T. vulgaris essential oils were obtained fro...

The essential oils associated with the flowers of Tithonia diversifolia (Hemsl.) A. Gray were extracted and characterized via hydrodistillation and Gas Chromatography. Hydrodistillation was done in an all-glass Clevenger-type apparatus. The extracts from the hydrodistillation were subjected to gas chromatography where the components of the essential oils were separated based on their molecular ...

In this study, the chemical composition of the essential oils (EOs) extracted from aerial parts of native populations of Origanum vulgare ssp. vulgare from Iran was compared by GC and GC/MS. Plants were collected at bloom stage from their natural habitats located in Kaleybar, Sabalan, Meshkin Shahr and Chalus regions, respectively from East Azerbaijan, Ardabil, Ardabil and Mazandaran provinces....
