There is an increasing demand for inexpensive and safe anesthetics that can reduce fish stress caused by some procedures such as capture and handling. In this context, the present study evaluated the potential of essential oils (EO) of three Brazilian native plants (Hesperozygis ringens, Lippia sidoides and Ocotea acutifolia) as anesthetics for the silver catfish Rhamdia quelen. Moreover, an an...

Thyme Essential oils (EO) with antimicrobial and antioxidant properties are widely used in pharmaceutical, cosmetic, and perfume industry. It is also used for flavoring and preservation of several foods. Nowadays, packaging research is receiving a considerable attention due to the development of eco-friendly materials made from natural polymers such as starch and chitosan. In this study Thymus ...

As part of ongoing research on the chemical composition and the antimicrobial properties of Burkinabe plants essential oils alone and in combination, essential oils (EOs) from leaves of Cymbopogon citratus and Cymbopogon giganteus from Burkina Faso were analyzed by GC-FID and GC-MS. Five constituents, which accounted for 96.3% of the oil, were identified in the EO of C. citratus. Geranial (48.1...

The aim of this study was to compare the effects of dietary supplementation of ajwain (Trachyspermum ammi) and thyme (Thymus vulgaris) essential oils(EO)on nutrients digestibility, blood parameters and growth performanceof neonatal dairy calves during eight weeks. Sixty suckling dairy calves with an initial body weight (43.2±3.8 kg) were randomly allocated to five treatments including CO, contr...

abstract essential oils (eos) of achillea eriophora, extracted by hydrodistillation and their constituents were analyzed by gas chromatograph (gc) and gc/mass spectrometry using retention indices and fragmentation patterns. the antibacterial effects of the eo was assessed on several food-borne pathogens, namely staphylococcus aureus, bacillus cereus, escherichia coli o157:h7, salmonella enterit...

Fungus Candida albicans has received much attention due to its oral, vaginal and/or systemic candidiasis. This study was undertaken to find out the optimum antifungal effect of concentration of two essential oils namely Thymus daenensis Celak. and Zataria multifera Boiss. either alone or in combination ratio and their time of action against C. albicans. The essential oils (EOs) were obtained by ...

Hop (Humulus lupulus L) is cultivated worldwide for two purposes of aroma and bitter taste. The main objective of this study was to determine the predominant characteristic of hop cultivated in Iran using GC-MS analysis of essential oils obtained from fresh and heat dried hop strobiles. Essential oils (EO) of female flowers of hop (Humulus lupulus L.) cultivated in Gorgan, Iran were obtained by...

In this study, both qualitative and quantitative analyses of chemical composition of M. purpurea essential oil obtained in the Deryng and Clevenger-type apparatuses were compared. As a result, content of volatile compounds were: 785.67 mg/mL and 833.33 mg/mL in the oil obtained in the Deryng (D-EO) and Clevenger-type apparatuses (C-EO), respectively. The major components of both essential oils ...
