Effects of Baoyuan Anticancer Oral Solution on Scavenging of O-2 and DPPH Free Radi-cals / 医药导报

Objective To investigate the scavenging effect of Baoyuan anticancer oral solution on superoxide anion (O-2 ) and 1,1-diphenyl-2-picrylhydrazyl hydrate(DPPH) free radicals. Methods O-2 and DPPH were examined with the ESR (electron spin resonance) spin trapping method. Results The scavenging effect of Baoyuan anticancer oral solution diluted to 50 fold, on O-2 and DPPH free radicals was 81. 32% and 98. 47% , respectively. Conclusion Baoyuan anticancer oral solu-tion has a dose-related effect on free radical elimination.
