Superoxide anion scavenging

Superoxide anion scavenging activity of the enzymatically synthesized poly(catechin) was evaluated. Poly(catechin), synthesized by HRP catalyst, greatly scavenged superoxide anion in a concentration-dependent manner, and almost completely scavenged at 200 p.M of a catechin unit concentration. The laccase-catalyzed synthesized poly(catechin) also showed excellent antioxidant property. Catechin showed pro-oxidant property in concentrations lower than 300 jlM. These results demonstrated that the enzymatically synthesized poly(catechin) possessed much higher potential for superoxide anion scavenging, compared with intact catechin. [Pg.241]

Also in the superoxide anion scavenging assay in the phenazine methosulfate/NADH-nitroblue tetrazolium system, garcinol exhibited potent superoxide anion scavenging activity almost comparable to that of gallic acid and stronger than that of (+)-catcchin [60]. [Pg.706]

L-Carnitine attenuated doxorubicin-induced lipid peroxidation in male Wistar rats (Luo et al. 1999). In vitro, L-propionylcarnitine showed a dose-dependent superoxide anion-scavenging activity, inhibited peroxidation of linoleic acid, and protected pBR322 DNA from cleavage induced by H2O2 UV-photolysis (Vanella et al. 2000). [Pg.743]

For some stictic acid derivates, Lohezic-Le Devehat et al. (2007) found moderate antiradical activity in the l,l-diphenyl-2-picrylhydrazyl (DPPH) assay and very high superoxide anion scavenging activity. [Pg.119]

Antioxidant activities of major lichen metabolites in Hypogymnia physodes lichen (physodic acids, atranorin and usnic acid) were studied by Rankovic et al. (2014b). An physodic acid was found to be the most effective antioxidant in free radical and superoxide anion scavenging, as well as in reducing power assays among tested lichen metabolites. [Pg.121]
