Blumeatin 是从Blumea balsamiferaDC中分离得到，对 CCl4 和硫代乙酰胺 (TAA) 所致的肝损伤表现出保护活性。

Blumeatin has antioxidant properties, free radical scavenging activity,and has xanthine oxidase (XO) inhibitory activity.

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]
