Physico-chemical and Sensory Properties of Tarhana Prepared from Different Cereals and Dairy Ingredients
Tarhana is a traditional fermented food made from cereals and yoghurt mixture and popular in some European and African countries. In this study, the effects of wheat, oat or barley flour with cow or goat yoghurt on the physico-chemical and sensory properties of Tarhana were investigated. A gradually increased in acidity of all prepared Tarhana dough samples was found during ... إقراء المزيد

Improving drought and salinity tolerance in barley by application of salicylic acid and potassium nitrate
Growth and physiological activities of barley (_Hordeum vulgare_ L. cv. Gustoe) grown in soil cultures were evaluated to recognize the ameliorative role of salicylic acid (SA) and KNO3 against the negative effects of salt and water deficit stresses. Barley plants were subjected to three levels of NaCl (50, 100 and 150 mM), three levels of water stress (80%, 70% and ... إقراء المزيد

Screening of antioxidant activity of some essential oils
ABSTRACT: The essential oils that possess antioxidant activity have been the subject of many investigations resulting in the screening of many medical plants and have revealed structurally unique biologically active compounds. An antioxidant is a substance that retard oxidation by inhibiting initial free radical formation or by preventing them from producing more free radicals which can perpetuate the reaction. The ... إقراء المزيد

Physicochemichal properties, DNA interaction, antiviral and antioxidant activities of some Amino Acid Imine Chelates
Schiff base amino acid ligands which derived from the condensation of 3-methoxysalicylaldehyde (MS) or 4-diethylaminosalicylaldehyde (DS) with some of α-amino acids (Phenylalanine (Phe), Histidine (His), Tryptophan (Trp)) were prepared. Moreover, eleven Schiff base amino acid binary Fe(II) and Cu(II) complexes were prepared. In addition to, five ternary Cu(II) complexes which derived from the prepared Schiff base amino acid ligands as ... إقراء المزيد

Some new nano-sized Cr(III), Fe(II), Co(II), and Ni(II) complexes: Structural characterization, electrochemical, antioxidant, antimicrobial, antiviral assessment and DNA interaction
To estimate the biological preference of synthetic small drugs towards DNA target, new metal based chemotherapeutic agents of nano-sized Cr(III), Fe(II), Co(II) and Ni(II) Schiff base complexes having N,N,O donor system were synthesized and thoroughly characterized by physic-chemical techniques. The redox behavior of the Cr(III), Fe(II) and Co(II) complex was investigated by electrochemical method using cyclic voltammetry. IR results proven ... إقراء المزيد

Electrochemical Determination of the Antioxidant Activity in Echinacea Purpurea Roots Using Square Wave Voltammetry
A simple and rapid electrochemical method was established to quantify the total polyphenol (TP) content and assess their antioxidant activity (AA) in roots of three _Echinacea purpurea_ (_E. purpurea_) species using square wave voltammetry (SWV). Individual polyphenol components were identified, and then quantified by ultra‐high performance liquid chromatography coupled with mass spectrometery (UPLC‐MS). Two major polyphenols, chicoric (ChA) and caftaric ... إقراء المزيد
