this experiment was conducted to evaluate the effects of fennel and thymyus valgaris extracts with and without flaxseed on performance and egg quality of laying hens (hy line w-36). the experiment was conducted in a completely randomized design with 200 laying hens in 5 treatments and 5 replicates (with 8 hen in each replicate) for 12 weeks. the hens were fed isocaloric and iso nitrogenous diet...

Entrohemorrhagic Escherichia coli is a human pathogen that causes hemorrhagic colitis due to its verotoxin. It is an agent with food poisoning importance; a significant number of cases subsequntly develop hemolitic uremic syndrome (HUS) which is probably the most common cause of renal failure in childeren and occasionally resulting in death. Inhibition of bacterial growth in food is the most im...

Background: Because of increasing resistance to current antibiotics, many attempts have been made by the researchers to find new compounds of plant derivatives as substitute for non-effective antibiotics. This research was performed to study the antibacterial properties of aquatic and alcoholic extracts of thyme on the clinical and standard strains of enterohemorrhagic Escherichia coli. Materi...

Properties of thyme extracts from three different species (Thymus vulgaris, Thymus zygis, and Thymus hyemalis) were examined. Two oil fractions from each species were obtained by CO(2) supercritical fluid extraction. Main compounds presented in the supercritical extracts of the three thyme varieties were 1,8 cineole, thymol, camphor, borneol, and carvacrol. As a cellular model of inflammation/a...

The objective of this work is to develop a novel coacervation process to produce microcapsules of polylactide (PLA) to encapsulate thyme oil that will be used in cosmetics. The novelty of this approach consists of dissolving PLA in dimethylformamide (DMF) which is a good solvent for PLA but in addition has high solubility in water. Upon contact with water, the homogeneous solution of PLA in DMF...

the methanolic extracts, infusions, decoctions and hydrosols of six plants were investigated for their total phenolic contents, antioxidant and antimicrobial activities: mentha piperita (peppermint), thymus vulgaris   (thyme), melissa officinalis (lemon balm), ocimum basilicum (basil), rosmarinus officinalis (rosemary) and     salvia officinalis     (sage) (lamiaceae). total phenolic contents w...

A solvent system consisting of ethyl acetate, ethyl alcohol and water, in the volume ratio of 4.5:4.5:1, was developed and used to extract, at room temperature, betulin from white birch bark and antioxidants from spices (rosemary, thyme, sage, and oregano) and white oak chips. In addition, under reflux conditions, trimyristin was extracted from nutmeg using the same solvent system, and eugenol ...

Abstract Background Herbal medicinal products have a long-standing history of use in the therapy common respiratory infections. We sought to assess potential five validated herbal extracts regarding their ability restrict SARS-CoV-2 replication vitro : Bronchipret thyme-ivy (BRO TI), thyme-primrose TP), Imupret (IMU), Sinupret extract (SINx) and Tonsipret (TOP). Methods Vero cells were incubate...

The volatile composition of 21 herbhoneys (HHs) of 7 different botanical origins was characterised for the first time. Ultrasound solvent extraction (USE) and headspace solid-phase microextraction (HS-SPME) followed by GC-FID/MS were successfully applied as complementary methods for monitoring the volatile plant flavours added by the bees. HHs showed significant compositional variability relate...
