Ophiopogonanone A has oxygen free radicals(OFRs) scavenging effects, it can scavenge hydroxyl radical(·OH) and hydrogen peroxide(H2O2) in vitro.
体外活性
The scavenging effect of homoisoflavonoids isolated from O.japonicus extracts was examined on superoxide anion(O2·-),hydroxyl radical(·OH),and hydrogen peroxide(H2O2) by chemiluminescence. Ten homoisoflavonoids were obtained from O.japonicus extracts.They were identified as methylOphiopogonanone A(1),methylophiopogonanone B(2),Ophiopogonanone A(3),ophiopogonanone E(4),5,7-dihydroxy-6,8-dimethyl-3-(4'-hydroxy-3',5'-methoxybenzyl) chroman-4-one(5),methylophiopogonone A(6),methylophiopogonone B(7),desmethylisoophiopogonone B(8),5,7,2'-trihydroxy-8-methyl-3-(3',4'-methylenedioxybenzyl) chromone(9) and 5,7,2'-trihydroxy-6,8-dimethyl-3-(3',4'-methylenedioxybenzyl) chromone(10).
