Study of Scavenging Action of Longyanshen on Oxygen Free Radicals / 中国药房

ABSTRACT

OBJECTIVE:To study the scavenging action of Longyanshen on O2 ?- and ? OH.METHODS:Spectrophotometry (wavelength 322nm and 536nm)was used to detect the effects of Longyanshen upon O2 ?- and?OHRESULTS:Longyanshen in concentration of 30g/ml could reduce the level of?OH by 284%,and Longyanshen in concentrations of 15g/ml,30g/ml and 60g/ml could decrease the levels of O2 ?- by 441%,630% and 479% and inhibit the generation of O2 ?- by 489%,589%and 675% in vitro,respectivelyCONCLUSION:The results show that Longyanshen could scavenge and inhibit O2 ?- markedly(P
