background: essential oils and their major constituents are useful sources of antimicrobial compounds. there are a few reports on the decontamination and antimicrobial activity of essential oils towards shigella spp. m aterials and methods: in this study, the antimicrobial and decontamination potentials of essential oils at different concentrations, belonging to plants such as thymus vulgaris, ...

Chemical composition and in vitro antioxidant and anticholinesterase activities of essential oils obtained from leaves and flowers of Pistacia atlantica were studied. GC/GC-MS analyses of the essential oils afforded twenty-two compounds from flower oil and thirty from leaf oil. The antioxidant activity of the essential oils was determined using -carotene-linoleic acid, DPPH • and ABTS • -scav...

PURPOSE Carrying out the chemical composition and antiproliferative effects against cancer cells from different biological parts of Artemisia herba alba. METHODS Essential oils were studied by gas chromatography coupled to mass spectrometry (GC-MS) and their antitumoral activity was tested against P815 mastocytoma and BSR kidney carcinoma cell lines; also, in order to evaluate the effect on n...

effects of mentha arvensis l. and mentha pulegium l. essential oils were investigated against oviposition deterrence, egg hatching and adults' mortality of callosobruchus maculatus f. essential oils were obtained by dry leaves that were subjected to hydrodistilation using a modified clevenger-type apparatus. all experiments were conducted at 25±1ºc, 65±5 % r.h. in the dark condition with 5...

The antimicrobial activity of essential oils and their components has been recognized for several years. Essential oils are produced as secondary metabolites by many plants and can be distilled from all different portions of plants. The recent emergence of bacteria resistant to multiple antibiotics has spurred research into the use of essential oils as alternatives. Recent research has demonstr...

Streptococcus pyogenes plays an important role in the pathogenesis of tonsillitis. The present study was conducted to evaluate the in vitro antibacterial activities of 18 essential oils chemotypes from aromatic medicinal plants against S. pyogenes. Antibacterial activity of essential oils was investigated using disc diffusion method. Minimum Inhibitory Concentration of essential oils showing an...

Red ginger is known as one of the medicinnal and aromatic plants that have high value in form essential oils. The distillation red oils required large amounts water, then most water was disposed wastewater. This wastewater hydrosol, which still contains a small amount secondary metabolites such zingiberene geraniol. These compounds were considered to potential be utilized cosmetic products foot...

Thymus species are popular spices and contain volatile oils as main chemical constituents. Recently, plant-derived essential oils are gaining significant attention due to their significant biological activities. Seven different thymus-derived essential oils were compared in our study. First, we focused on their chemical composition, which was followed up by testing their effects on phagocytosis...

Family Cupressaceae is the largest coniferous plant family. Essential oils of many species belonging to family Cupressaceae are known to have several biological activities specially antimicrobial activity. The essential oils from aerial parts of Calocedrus decurrens Torr., Cupressus sempervirens stricta L. and Tetraclinis articulata (Vahl) Mast. were prepared by hydrodistillation. The chemical ...

Abstract The main limitation of the micropropagation camu-camu (Myrciaria dubia) is related to in vitro contamination. In order overcome contamination, effect essential oils was studied as an alternative conventional chemical treatments. This study aimed analyze action from four condiment and medicinal plants (Oregano, Origanum vulgare L.; Garlic, Allium sativum Citronella, Cymbopogon nardus L....
