The quenching of singlet molecular oxygen (1O2) by the flavylium cation form of six widespread anthocyanin derivatives: cyanidin 3-glucoside (CG), cyanidin 3-rutinoside (CR), cyanidin 3-galactoside (CGL), malvidin (M), malvidin 3-glucoside (MG) and malvidin 3,5-diglucoside (MDG) was studied in 1% HCl methanol solution by time-resolved phosphorescence detection (TRPD) of 1O2 and photostationary actinometry using perinaphthenone and methylene blue as sensitizers, respectively. The average value…

LC-MS/MS analysis of the photolyzed solutions supports the product identification as 2-decarboxy-2,3-dehydrobetanin, based on the molecular ion [M](+) observed at m/z 505, and betanin also undergoes a similar photooxidation reaction.

Singlet oxygen quenching and radical scavenging capacities of structurally-related flavonoids present in Zuccagnia punctata Cav.

The theoretical calculations for both the gas and solution phases at the B3LYP level of theory for the Osanger reaction field model agreed with the experimental findings, thus supporting the characterization of the antioxidant mechanism of the Z. punctata flavonoids.

Determination of singlet oxygen quenching and antioxidant activity of Bieckols isolated from the brown alga Eisenia bicyclis

In this study, we determined 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging activities as well as the reducing power for

Triplet Excited States and Singlet Oxygen Production by Analogs of Red Wine Pyranoanthocyanins

The strong visible light absorption, the relatively small singlet‐triplet energy differences, the excited state redox potentials and the reasonably long lifetimes of pyranoflavylium triplet states in the absence of molecular oxygen suggest that they might be useful as triplet sensitizers and/or as cationic redox initiators in polar aprotic solvents like acetonitrile.

Kinetic study of the quenching reaction of singlet oxygen by flavonoids in ethanol solution.

The quenching rate of singlet oxygen (1O2) by seven kinds of flavonoids with 2,3-double bonds has been measured spectrophotometrically in ethanol at 35 degrees C, and the result suggests that these flavonoid may contribute to the protection of oxidative damage in foods and plants, by quenched 1O2.
