General description

Taxifolin or dihydroquercetin is a naturally occurring secondary metabolic compound found in many plants such as onions, milk thistle, Douglas fir bark, and French maritime pine bark.

Application

(±)-Taxifolin hydrate has been used to evaluate its effects when co-supplemented with trehalose to improve the quality of post-thawed ram semen. It may have been used as a reference standard to analyze the bioactive components of ethanolic extract of P. orientale (POE) using high-performance liquid chromatography (HPLC).

Biochem/physiol Actions

(±)-Taxifolin exerts various pharmacological properties that include anti-inflammatory, anti-cancer, antiviral, and antimicrobial activities. It displays neuroprotective, hepatoprotective effects, and it also protects against cardiovascular diseases.
Flavonoid, antioxidant. Inhibits lipogenesis in cancer cells, most likely by targeting fatty acid synthase activity.
