Superoxide scavenging activities of sixty Chinese medicines determined by an ESR spin-trapping method using electrogenerated superoxide.

چکیده
Superoxide-scavenging activities of 60 kinds of Chinese herbal medicines were determined accurately by an electron spin resonance (ESR) spin-trapping technique using 5,5-dimethyl-1-pyrroline 1-oxide (DMPO) as a spin-trapping reagent. As a source of superoxide in this method, superoxide generated by one-electron reduction of the oxygen molecule in dimethyl sulfoxide solution was used. As a result of these studies, very powerful scavenging activity was found in Chinese medicines for inflammation, diseases of blood circulation and for tumors.

A discrepancy in superoxide scavenging activity between the ESR-spin trapping method and the luminol chemiluminescence method.
In a previous study of ours, the superoxide scavenging activity of aqueous extracts from dinophycean red tide flagellates was detected by an electron spin resonance (ESR)-spin trapping method, but not by an L-012 (luminol analog)-dependent chemiluminescence (CL) method. To investigate the discrepancy between the two methods, the effect of ferric-protein complexes on superoxide scavenging activi...
متن کاملElectron spin resonance analysis of superoxide anion radical scavenging activity with spin trapping agent, diphenyl-PMPO.
Recently, a novel electron spin resonance (ESR) spin-trapping agent, 2-(diphenylphosphinoyl)-2-methyl-3,4-dihydro-2H-pyrrole N-oxide (Diphenyl-PMPO), was synthesized. Because it had some advantages in stability and reactivity over conventional spin-trapping agents, we applied it to the ESR analyses of superoxide anion radical scavenging activity (SOSA) of superoxide dismutase (SOD) and of well-...

The generation of superoxide anion or hydroxyl radical derived from the organic selenium compounds selenomethionine, selenoethionine, selenocystine, selenocystamine and selenocysteine-glutathione selenenyl sulfide (CySeSG) was investigated by the electron spin resonance (ESR) technique with 5,5-dimethyl-1-pyrroline Noxide (DMPO) as a spin trapping agent. The intensity of ESR signals of DMPO-OOH...
متن کاملSpin Trapping Technique Studies on Active Oxygen Radicals from Human Polymorphonuclear Leukocytes during Fluoride-stimulated Respiratory Burst
By means of the ESR spectrum technique it was demonstrated that fluoride (F-) stimulated human polymorphonuclear leukocytes (PMN) in a respiratory burst to generate active oxygen radicals ( • 02 and -OH) and to consume oxygen (02). The experiments' using the spin trapping technique with the nitrone DMPO as the trapping agent indicated that the PMN produce the adduct DMPO-OOH under high concentr...
متن کاملStructure Effect on Antioxidant Activity of Catecholamines toward Singlet Oxygen and Other Reactive Oxygen Species in vitro
The reactivity of catecholamine neurotransmitters and the related metabolites were precisely investigated toward 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and reactive oxygen species. Catecholamines reacted immediately with DPPH radicals, their reactivity being stronger than that of ascorbic acid as a reference. Superoxide scavenging activities of catecholamines determined by WST-1 and elec...
