Black Tea Extract Mediated Green Synthesis of Copper Oxide Nanoparticles
Copper oxide nanoparticles were synthesized using black tea extract and copper nitrate as thecopper source by the green method at different calcination temperatures. This method has manyadvantages such as nontoxic, economic viability, ease to scale up, less time consuming andenvironmental friendly approach for the synthesis of CuO nanoparticles without using any organicchemicals. The synthesize...
متن کاملThe efficacy of black tea in ameliorating endothelial function is equivalent to that of green tea.
Consumption of tea has been shown to improve endothelial function. It is assumed that catechins are the tea components responsible for these beneficial effects. In black tea, catechin concentrations are significantly lower than in green tea. The present study was designed to compare green and black tea with regard to amelioration of endothelial function. Endothelial function in response to both...
متن کاملEffect of red wine on endothelium-dependent relaxation in rabbits.
1. Published data on the effects of red wine, ethanol and flavonoids on endothelium-dependent relaxation are equivocal. The present study was undertaken to determine the effects of red wine, ethanol and selected flavonoids present in red wine on endothelium-dependent relaxation. 2. Aortic rings from New Zealand White rabbits were set up in organ baths (20 ml) and contracted with noradrenaline (...
متن کاملCreaming in black tea.
Tea cream is the precipitate formed as tea cools. Its formation has been studied by X-ray scattering, and it is shown that a higher tea concentration leads to earlier onset of creaming and larger particles and that addition of theaflavin and calcium promotes creaming. Association constants between the major components of black tea have been obtained using NMR and show that calcium and glucose e...
متن کاملVascular endothelial growth factor-mediated endothelium-dependent relaxation is blunted in spontaneously hypertensive rats.
The vasodilatory effect of VEGF has not been characterized in the setting of hypertension. This study investigated the in vitro vasorelaxant effects of VEGF in organ chambers in the aorta of the adult (12-week-old) spontaneously hypertensive rats (SHR), young (4-week-old) SHR without hypertension, and age-matched Wistar-Kyoto (WKY) rats compared with acetylcholine (ACh). Cumulative concentratio...
