Taxifolin-rich extract from Siberian Larch

Taxifolin- rich extract (Taxifolin, Dihydroquercetin, DHQ), with high-order crystal structure is a natural bioflavonoid, extracted from the wood of Dahurian or Siberian larch tree. Taxifolin with the highest antioxidant capacity, and the ability to bind free oxygen radicals, that can cause negative changes in the human body cells, to prevent body-aging processes, to preserve and increase body's natural immune capabilities, can extend human life by 20-25 years.Chemical name: [(2R,3R)-2-(3,4 dihydroxyphenyl)-3,5,7-trihydroxy-2,3-dihydrochromen-4-one, also called (+) trans (2R,3R)- dihydroquercetin] 

Chemical formula: C15H12O7; molecular weight: 304,25

Taxifolin-rich extract is free of GMO products and free from BSE (Bovine spongiform encephalopathy - known as mad cow disease).

Due to its powerful anti-oxidative and capillary protection activities Taxifolin-rich extract (DHQ) is most widely used in dietary supplements and pharmaceutical products. DHQ is compatible with vitamins, mineral complexes, and medicinal plant extracts.

Taxifolin-rich extract proven biological effects include:

  • Anti-oxidative activity
  • Vitamin P activity
  • Capillary protection: improving microcirculation and blood flow at the capillary level, promoting the development of new capillaries
  • Helping to maintain blood pressure at physiological levels, providing a mild hypotension effect
  • Improvement of the elasticity of red blood cells, reduction of blood viscosity
  • Improvement of the coronary blood flow and myocardial contractility, reduction of the affected zone of the cardiac muscle
  • Anti-ischemic effect
  • Antidepressant effect
  • Reduction of the low density lipoprotein levels in blood plasma
  • Stomach protection
  • Liver protection
  • Immune system regulation
  • Inactivation of cytotoxic substances
  • Radiation protection
  • Synergist to vitamins А, С, Е

Taxifolin in Food Industry

The Taxifolin application in the food industry does not modify organoleptic properties of the food products.

Adding to pre-packed foods to cause a health benefit as antioxidant and anti-inflammatory agent, accelerates stability over 30 weeks, corresponding to 5 years of normal shelf life.

Taxifolin can reduce the lipid peroxidation, with the prolongation of food products shelf life in 1.5 – 4.0 times. The presence of even small amounts of DHQ prevents an "oxidative stress" and also helps to protect the body against free radicals.

Performance and endurance training, required in professional sports, is closely related to the training of one’s cardiovascular system in order to adapt it to exercise workload. This is especially important during the competition period, when physical demands are at their peak and athletes strive to push their limits.

An individual, undergoing intense physical training, utilizes oxygen at levels exceeding 75% of maximum values. The challenge here is that sustained physical exercise may result in an inadequate supply of oxygen to working muscles (known as tissue hypoxia), a result of insufficient blood supply to the tissues due to poor microcirculation.

Moreover, during maximal exercise, the metabolism of the tissue is violated. Muscles accumulate lactic acid, which causes fatigue and complicates recovery after training.

Studies show that the application of taxifolin is able to solve these problems very efficiently. Specifically, taxifolin is able to:

  • Improve intracardial hemodynaimcs and intensify blood flow to the myocardium
  • Help to return pathologic microcirculation to normal, thus, optimizing tissue blood flow
  • Contribute to the redistribution of blood flow within small arteries, thus, enhancing blood supply to ischemia-affected tissues
  • Enhance blood flow to muscles
  • Enhance pulmonary mechanics and improve lung ventilation and blood gas composition
  • Help to increase РО2 (oxygen partial pressure) and blood oxygenation.

Taxifolin in Cosmetics

DHQ can be utilized in cosmetics, specifically to preserve raw material, oil and fat components, finished products; render therapeutic effects to products.

Enhance protective functions of the skin against external and internal toxicity, radiation, germs, and other environmental factors; normalize general metabolic processes through topical application, those in lymphatic and blood system; renew skin and slowing skin aging.
