摘要/Abstract

摘要：

In vitro antioxidant activities of resveratrol and piceid against peroxynitrite(ONOO^-) were examined by the inhibition of 3-nitrotyrosine formation. Trolox was used as a positive control. Resveratrol and piceid exhibited high ONOO^--scavenging activities in a concentration dependent manner. The antioxidant activities(the concentration of test compound required to yield a 50% inhibition of tyrosine nitration, IC₅₀) of resveratrol and piceid against ONOO^- were (48.34±0.97) and (74.69±1.49) μmol/L, respectively. Compared with that of trolox[(105.40±1.16) μmol/L], their scavenging activities were 2.2- and 1.5-fold higher for resveratrol and piceid. Formation of nitro-resveratrol as shown by UV-Vis spectroscopy and liquid chromatography-tandom mass spectrometry(LC-MS/MS) analysis indicates that resveratrol could directly scavenge ONOO^- via nitration reaction. Our results demonstrate that foods and medicinal herbs with resveratrol and piceid as stronger ONOO^- scavengers are valuable ingredients and have healthy application in preventing humans from peroxynitrite-mediated oxidative damage by scavenging peroxynitrite efficiently.
