This study was conducted to assay the effects of methanol foliar application (0, 10, 20 and 30% v/v) and bed cover (control, white and black covers) on yield and some physiological traits of marigold as a factorial based on RCBD. The results revealed the significant interaction effects of bed cover and methanol foliar application on chlorophyll a content and plant height. The highest plant heig...

Extraction parameters in classical solvent extraction of bioactive compounds from Arbutus unedo leaves were studied using a single factor experiment approach. Effects ethanol (EtOH) concentration (20-100 %), solvent:solid ratio (10-90 ml/g), time min) and temperature (15-70 °C) on total phenolic content (TPC), flavonoid (TFC) antioxidant activity (TAA) the extracts investigated. The optimal con...

This study is focused on the recovery of polyphenols from vegetable and fruit residues further evaluation antioxidant features extracts. Spinach orange have been selected as representative matrices for a more comprehensive since they contain significant amount that could be used in food, pharmaceutical and/or cosmetic industries. Extraction spinach waste was performed using three extraction tec...

Abstract Carotenoids have a wide range of applications in the food, pharmaceutical, and cosmetic industries as natural coloring agents antioxidants. Consequently, are more concerned about extracting them from resources by-products. The present research aimed to evaluate extraction efficiency carotenoids orange peels using hydrophobic deep eutectic solvents (HDESs) alternatives for organic solve...

FW (g mol-1) 1180.4

Objective(s) The aims of present study were to elucidate the effect of NaHS as a H2S donor on precontracted rat trachea smooth muscle, role of epithelium and nitric oxide in this action. Materials and Methods Tracheal rings from male adult Wistar rats were isolated and mounted in an organ bath containing Krebs–Henseleit solution under 1.5 g resting tension and contractions were recorded isom...

‘smyrna’ type figs (zidi ‘zd’: dark fruit and thgagli ‘thg’; bidhi ‘bd’ and khedri ‘khd’: white fruit) originated from two areas of fig production in tunisia were subject to physico-chemical description and spectrophotometric analysis for their sugar (glucose, fructose and sucrose) and organic acid (citric and malic) contents. fruit weight ranged between 54 and 82 g, fruit width between 47 and ...

Deliberate and natural outbreaks of infectious disease, the prevalence of antibiotic resistant strains, and the ease by which antibiotic resistant bacteria can be intentionally engineered all underscore the necessity of effective vaccines and continued development of novel antimicrobial/antiviral therapeutics. Isoprenes, a group of molecules fundamentally involved in a variety of crucial biolog...

With the advancement in nanotechnology, use of nanoparticles has been enhanced dramatically biomedical, agriculture, and industrial processes. However, combined effect bacteria on plant growth heavy metal (Cd, Cr, Cu, Pb)-contaminated wastewater is greatly limited. Therefore, recent work was designed to determine synergistic impact green synthesized zinc oxide (ZnO-NPs) (5-10 mg/L) Bacillus spp...

Few studies have made direct estimates of the energy required for ion transport in gills of freshwater (FW) and seawater (SW) fish. Oxygen consumption was measured in excised gill tissue of FW-adapted cutthroat trout ( Oncorhynchus clarki clarki) to estimate the energy cost of NaCl transport in that osmoregulatory organ. Ouabain (0.5 mM) and bafilomycin A1 (1 μM) were used to inhibit the Na+-K+...
