| Description | Ophiopogonanone E has oxygen free radicals(OFRs) scavenging effects, it can scavenge hydroxyl radical(·OH) and hydrogen peroxide(H2O2) in vitro. |
| In vitro | 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). |
