What is The radical scavenging activities of radix puerariae isoflavonoids: A chemiluminescence study about?
The purpose of this paper was to determine the radical scavenging activities of radix puerariae isoflavonoids (RPI) toward different reactive oxygen species (ROS), including superoxide anion(O ÅÀ 2 ), hydroxyl radical (OH Å ), lipid-derived radicals (R Å ) and singlet oxygen ( 1 O 2 ), using a chemiluminescence technique. RPI used here contained puerarin (PU), daidzin, daidzein and others as tested by HPLC. O ÅÀ 2 , OH Å , R Å , and 1 O 2 were generated from a pyrogallol autoxidation system, Fenton reaction system, H 2 O 2induced oxidation of unsaturated fatty acid system and NaClO-H 2 O 2 system, respectively. RPI could effectively scavenge O ÅÀ 2 , OH Å , R Å , and 1 O 2 at EC 50 of 0.08, 0.005, 0.03, and 0.004 mg/ml, respectively. In addition, the radical scavenging activities of RPI were much higher than that of its main component PU, and similar to that of tea polyphenols, indicating that RPI, not PU, was a powerful antioxidant.
