Radical chemistry of epigallocatechin gallate and its relevance to protein damage



Radical chemistry of epigallocatechin gallate and its relevance to protein damage



Archives of Biochemistry and Biophysics 414(1): 115-120



The radical chemistry of the plant polyphenolics epigallocatechin gallate (EGCG) and epigallocatechin (EGC) were investigated using electron paramagnetic resonance spectroscopy. Radical species formed spontaneously in aqueous solutions at low pH without external oxidant and were spin stabilized with Zn(II). The spectra were assigned to the gallyl radical and the anion gallyl radical, with only 10% of the signal assigned to a radical from the galloyl ester.
