Polyphenolic flavanols as scavengers of aqueous phase radicals and as chain-breaking antioxidants.
TLDR
Against propagating lipid peroxyl radical species, epicatechin and catechin are as effective as ECG and EGCG, the least efficacious being EGC and GA. Expand
A single dose of tea with or without milk increases plasma antioxidant activity in humans
TLDR
Consumption of a single dose of black or green tea induces a significant rise in plasma antioxidant activity in vivo, and addition of milk to tea does not abolish this increase. Expand
Bioavailability of catechins from tea: the effect of milk
TLDR
Catechins from green tea and black tea are rapidly absorbed and milk does not impair the bioavailability of tea catechins. Expand
No effect of consumption of green and black tea on plasma lipid and antioxidant levels and on LDL oxidation in smokers.
TLDR
It is concluded that consumption of black or green tea (6 cups per day) has no effect on plasma lipids and no sparing effect on Plasma antioxidant vitamins and that intake of a high dose of isolated green tea polyphenols decreases plasma vitamin E. Expand
The antioxidant properties of theaflavins and their gallate esters — radical scavengers or metal chelators?
TLDR
Spectroscopic studies show that all the compounds chelate iron and copper; enhanced absorbance in the visible region is observed in the case of the iron‐digallate complex, but not with copper. Expand
Total antioxidant activity of low density lipoproteins and the relationship with α‐tocopherol status
TLDR
A rapid method is described for measuring the antioxidant activity of low density lipoproteins and results show a positive correlation between the antioxidants activity and α‐tocopherol content of LDL in the supplemented group. Expand
Antioxidant fortified margarine increases the antioxidant status
TLDR
Consumption of moderate doses of vitamin E, vitamin C, α-carotene and β- carotene, supplied in a full-fat margarine and consumed as part of a normal diet, effectively increases the blood levels of these antioxidants. Expand
