The objective of this study was to evaluate the growth performance and meat quality feedlot Aberdeen Angus steers fed high-concentrate diets with or without a natural feed additive composed mixture yeasts essential oils (EO). A completely randomized design two (with additive) 12 replicates used. Twenty-four initial shrunk body weight 402.62±48.2 kg average age 18±2.0 months were Steers ad [...]

The method of electrospinning was used to create nanofibers made of cellulose acetate (CA) and essential oils (EOs). CA polymer at 15% w/v was dissolved in acetone and then 1% or 5% v/v of EOs was added to the polymer solution. The utilized essential oils were rosemary and oregano oils. Then, the CA/EOs in acetone solution were electrospun, creating micro/nanofibers, approximately 700-1500 nm i...

the genus tanacetum is one of the most important medicinal plant that contains 26 species in iran, 12 of them are endemic. this paper reports the essential oil (eo) composition of tanacetum polycephalum subsp. polycephalum growing wild in iran.  flowers and leaves were collected from different location of azerbaijan province (marand, mianeh and tabriz), hydro-distilled to produce the oils and a...

The phytoconstituents of the essential oil isolated by hydrodistillation and solvent extracts (PE, BZ, DCM, EtOAc EtOH) mature rhizomes turmeric (Curcuma pseudomontana) were analyzed GC–MS. major constituents identified in Benzofuran (6.93%), γ-Curcumene (11.18%), β-Elemenone (22.14%), Germacrone (15.15%), Phenol, 2-Methyl-5-(1,2,2-trimethylcyclopentyl)- (29.58%), Germacrene (8.78%), Italicene ...

AIM To compare the immediate antibacterial effect of two application methods (passive immersion and active mouthwash) of two antiseptic solutions on the in situ oral biofilm. MATERIAL AND METHODS A randomized observer-masked crossover study was conducted. Fifteen healthy volunteers wore a specific intraoral device for 48 h to form a biofilm in three glass disks. One of these disks was used as...

In the current study, a green method that can be easily used in different industrial applications, based on modification of sodium exchanged montmorillonite (Na+-Mt) with essential oils (EO) such as thyme oil, thymol and carvacrol was presented. The obtained results show prepared clays-essential hybrids were promising nanomaterials to encapsulate active compounds control their release selective...

Essential oils (EOs) are natural compounds extracted from plants that exhibit antimicrobial and antioxidant properties. therefore attract interest as additives in the food industry. especially for special populations. In case of children diagnosed with Cerebral Palsy. another factor has to be considered. such consistency food. This study evaluated consumer acceptability infant oregano essential...

This work aimed to evaluate the chemical composition, yield, and antifungal activity of essential oils (EO) native species from ‘Campos de Cima da Serra’ region, South Brazil. The Aloysia gratissima, lycioides, Blepharocalyx salicifolius, Cunila angustifolia, Myrciaria delicatula, Myrcia brasiliensis, Ocimum sp., Schinus polygama had an EO yield higher than 0.1% v/m. in vitro these was tested o...

BACKGROUND The incidence of fungal infections, especially those caused by Candida yeasts, has increased over the last two decades. However, the indicated therapy for fungal control has limitations. Hence, medicinal plants have emerged as an alternative in the search for new antifungal agents as they present compounds, such as essential oils, with important biological effects. Published data dem...

BACKGROUND The purpose of this study was to review the literature on the effects of a mouthrinse containing essential oils (EO) on plaque and parameters of gingival inflammation. METHODS The MEDLINE and Cochrane Central Register of Controlled Trials were searched up to and including December 2006 to identify appropriate studies. The primary outcome measure was gingivitis. Secondary parameters...
