Taxifolin, also known as dihydroquercetin, is a flavonoid compound belonging to the subclass of flavanonols. It is a natural bioactive substance widely found in various plants, including onions, milk thistle, and particularly in the bark of coniferous trees like Siberian larch (*Larix sibirica*). Its chemical structure is characterized by a flavanone backbone with hydroxyl groups at positions 3, 5, 7, 3', and 4'. Taxifolin has garnered significant interest in the pharmaceutical and nutraceutical industries due to its potent antioxidant, anti-inflammatory, and free radical scavenging properties. Its primary research and application focus is in the field of medicine, where it is investigated as a potential active pharmaceutical ingredient (API) or a key intermediate for drug development. Studies have explored its therapeutic potential in areas such as cardiovascular health, liver protection, and notably, in cancer prevention and therapy, where it may exhibit chemopreventive and anti-proliferative effects. Beyond its direct pharmaceutical applications, taxifolin is also a valuable reference standard and a subject of research in life sciences for studying flavonoid metabolism and biological pathways. It is commercially available as a high-purity standard for analytical purposes and as a raw material for dietary supplements.
