The effect of repeated heating process on edible oils namely, sesame oil (SO), sunflower oil (SFO) and palm oil (PO) with and without antioxidant, tertiary butyl hydroquinone (TBHQ) have been evaluated using ultrasonic velocity. The changes in physico-chemical properties of edible oils has been studied during repeated heating at 180 ± 5oC for 4 hrs/day and for 4 days. The effect of antioxidant,...
Essential Oils Composition, Anticholinesterase and Antioxidant Activities of Pistacia atlantica Desf
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...
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
Several bacterial strains were isolated from wild and reared fish and shellfish. The identification of these strains showed the dominance of the Aeromonas hydrophila species in all seafood samples, followed by Staphylococcus spp., Vibrio alginolyticus, Enterobacter cloacae, Klebsiella ornithinolytica, Klebsiella oxytoca and Serratia odorifera. The isolates were studied for their ability to prod...
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...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
BACKGROUND Nine Piper species with betel-like scents are sources of industrial and medicinal aromatic chemicals, but there is lack of information on cytotoxicity and genotoxicity for human safety, including how these plants impact human cervical cancer cell line. METHODS Plant leaves were extracted with hexane and hydro-distilled for essential oils. The extracts and oils were pre-clinically s...
BACKGROUND The Candida species are the most important factors of fungal infections in humans and animals. It is necessary to prepare antifungal or antimicrobial drugs because of increasing drug resistance. The natural treatment of diseases of bacterial origin using medicinal plants is important. In this study the effect of antimicrobial medicinal herbal essential oils and conventional antifunga...
