Electron-transfer mechanism in radical-scavenging reactions by a vitamin E model in a protic medium.
Org. Biomol. Chem. 3(4) , 626-9, (2005) The scavenging reaction of 2,2-diphenyl-1-picrylhydrazyl radical (DPPH.) or galvinoxyl radical (GO.) by a vitamin E model, 2,2,5,7,8-pentamethylchroman-6-ol (1H), was significantly accelerated by the presence of Mg(ClO4)2 in de-aerated methanol (MeOH). Such a... |

An on-line normal-phase high performance liquid chromatography method for the rapid detection of radical scavengers in non-polar food matrixes.
J. Chromatogr. A. 1216(43) , 7268-74, (2009) An on-line method for the rapid pinpointing of radical scavengers in non-polar mixtures like vegetable oils was developed. To avoid problems with dissolving the sample, normal-phase chromatography on bare silica gel was used with mixtures of hexane and methyl... |

Characterization of the radical-scavenging reaction of 2-O-substituted ascorbic acid derivatives, AA-2G, AA-2P, and AA-2S: a kinetic and stoichiometric study.
Biol. Pharm. Bull. 29(4) , 766-71, (2006) The aim of this study was to characterize the antioxidant activity of three ascorbic acid (AA) derivatives O-substituted at the C-2 position of AA: ascorbic acid 2-glucoside (AA-2G), ascorbic acid 2-phosphate (AA-2P), and ascorbic acid 2-sulfate (AA-2S). The ... |

Determination of reactions between free radicals and selected Chilean wines and transition metals by ESR and UV-vis technique.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 71(5) , 1638-43, (2009) Four different types of Chilean wines (Cabernet Sauvignon, Merlot, Carmenere and Syrah) were selected and examined in their free radical scavenging capacities by electron spin resonance (ESR) and spectrophotometric methods. The free radical scavenging propert... |

Antioxidant activity of alpha-pyridoin and its derivatives: possible mechanism.
Org. Biomol. Chem. 8(5) , 1058-63, (2010) alpha-Pyridoin (1, 1,2-di(2-pyridyl)-1,2-ethenediol) is a unique enediol antioxidant. To explore the detailed antioxidant mechanism of alpha-pyridoin, we synthesized alpha-pyridoin and its 5,5'- or 6,6'-bis-substituted derivatives (2-7) and compared their cap... |
