Increased intensity emission of the tert -butoxyl radical (2.9 times in relation to the starting level) was observed after the catalyst had been introduced into the reaction mixture, indicating a free radical mechanism for the reaction. 1999 Society of Chemical Industry...
The types of mutation caused by the alkoxyl radical-induced DNA damage were analyzed after transfection of the modified DNA into E. coli. The results show that the DNA damage induced by photoexcited BCBT most probably has to be attributed to tert-butoxyl radicals as the ultimate reactive ...

It is known that t-BuOOH is activated to radical reaction by the absorption of light at 254 nm 28.However, the substrates used in the present work, viz., chlorogenic acid and β-carotene have strong abso...

The rate constant was determined by measuring the phenoxyl radical formation rate at 390 nm as function of resveratrol concentration in acetonitrile. The rate constant was determined to be 6.5×108 M−1s−1. This high value indicates the high reactivity consistent with the strong antioxidant...
REGENERATION OF α-TOCOPHEROL FROM PHOTOCHEMICALLY GENERATED tert-BUTOXYL RADICAL INDUCED α-TOCOPHEROXYL RADICALS BY CHLOROGENIC ACID: A SYNERGISTIC INTERACTIONThe rates of oxidation of α-tocopherol and chlorogenic acid by tert-butoxyl radicals (t-BuO*) were studied by measuring the absorbance of ...

expt and cal values suggested that chlorogenic acid not only protected β-carotene from t-BuO radicals, but also regenerated β-carotene from β-carotene radical cation, formed by the reaction of β-carotene with t-BuO radicals. Results indicated a possible synergistic interaction between chlorogenic...
