Evaluation of the Peroxynitrite Scavenging Activity of Heat-Processed Ginseng

다국어 초록 (Multilingual Abstract)

To ascertain the principal active peroxynitrite (ONOO−) scavenging components of heat-processed Panax ginseng C.A. Meyer (sun ginseng [SG]), the ONOO− scavenging activities of fractions and components of SG were compared. The results demonstrated that the ONOO− scavenging ability of SG was due to its ether fraction containing phenolic compounds. High-performance liquid chromatography analysis and ONOO− scavenging activity tests of the phenolic acids contained in SG identified vanillic acid, ferulic acid, p-coumaric acid, syringic acid, and maltol as the main active ONOO− scavenging components of SG. The ONOO− scavenging activities of phenolic acids and maltol were dependent on the degrees of their proton donating ability.
