Protective Role of Black Tea against Oxidative Damage of Human Red Blood Cells

摘要: The purpose of our study was to explore the possible scavenging property black tea and catechins, major flavonols tea-leaf, against damage by oxidative stress. For this purpose, human red blood cell (rbc) taken as model induced a variety inducers, e.g. phenylhydrazine (PHX), Cu(2+)-ascorbic acid, xanthine/xanthine oxidase systems. Lipid peroxidation pure erythrocyte membrane whole could be completely prevented extract. Similarly, provided total protection degradation proteins. Finally, fluidity studies monitored fluorescent probe 1,6 diphenyl hexa 1,3,5-triene (DPH) showed considerable disorganization its architecture that restored back normal on addition or free catechins. Black extract in comparison catechins seemed better protecting agent various types Apparently, conversion partially polymerized products such theaflavin thearubigin during 'fermentation' process for making has no deleterious effect properties.
