The hydroxyl radical (OH.) quenching abilities of the following compounds were compared in the deoxyribose degradation system (initiated by the ferrous-ascorbate Fenton reaction): (a) 5 beta-scymnol, the hepatoprotective shark bile sterol, and its mono- and di-sulfate esters; (b) three marketed pycnogenol preparations (syn: proanthocyanidin--natural plant-derived polyphenolic bioflavonoids) extracted from pine tree (Pinus maritima) bark and grape (Vitis vinifera) seeds; and (c) two known… CONTINUE READING
