| Description | Blumeatin has antioxidant properties, free radical scavenging activity,and has xanthine oxidase (XO) inhibitory activity. |
| In vitro | The free radical scavenging activity of organic extracts of B. balsamifera DC leaves and that of pure flavonoids isolated from the leaves was evaluated using 1,1-diphenyl-2-picrylhydrazyl radical. A dose response curve was plotted for determining SC50 values (the concentrations required to inhibit radical formation by 50%). The antioxidant activities of crude extracts decreased in the order: methanol extract > chloroform extract > pet-ether extract. The antioxidant activities of all compounds tested decreased in the order: quercetin > rhamnetin > luteolin > luteolin-7-methylether > L-ascorbic acid > Blumeatin > butylated hydroxyanisole > 5,7,3',5'-tetrahydroxyflavanone > tamarixetin > butylated hydroxytoluene > alpha-tocopherol > dihydroquercetin-4'-methylether > dihydroquercetin-7,4'-dimethylether[1] |
