Powerful Antioxidant: A theoretical study of the conformational behavior and electronic structure of taxifolin correlated with the free radical-scavenging activity.
Anti-Inflammation Activity: The effect of taxifolin on the serum aminotransferase and tissue adenosine triphosphate (ATP) phosphohydrolase activity to elucidate the possible mechanism of its anti-inflammatory activity.
It ameliorates cerebral ischemia-reperfusion: Amelioration of CI/R injury by taxifolin may be attributed to its anti-oxidative effect, which in turn modulates NF-KB activation that mediates CI/R injury.

In food industry: Anti-oxidant additive to increase products shelf life (for instance pastry shelf life is increased 2-2.5 times). Artificial aging of wines, spirits, and cognacs; It also improves its taste while protecting human liver from destruction Perfume production and cosmetology;
