Blackcurrant Extracts and Their Main Functions

 

1. Anthocyanins

 

• Chemical Structure and Property: Anthocyanins are water - soluble pigments belonging to the flavonoid family. They are glycosides formed by anthocyanidins (the aglycone part) and sugars. For example, in blackcurrants, common anthocyanins include cyanidin - 3 - rutinoside and delphinidin - 3 - glucoside.
• Main Functions:
  • Antioxidant Activity: Anthocyanins have strong antioxidant properties. They can scavenge free radicals such as superoxide anions, hydroxyl radicals, and peroxyl radicals. By donating hydrogen atoms, they prevent the oxidation of lipids, proteins, and DNA in cells. For instance, in vitro studies have shown that anthocyanins can inhibit the oxidation of low - density lipoprotein (LDL), reducing the risk of atherosclerosis.
  • Vision Protection: They play a crucial role in eye health. Anthocyanins can improve microcirculation in the eyes and promote the regeneration of rhodopsin in the retina. This helps in enhancing visual acuity and relieving eye fatigue. They may also have a preventive effect on age - related macular degeneration and other eye diseases.
  • Anti - inflammatory Effect: Anthocyanins can inhibit the activity of inflammatory enzymes such as cyclooxygenase - 2 (COX - 2) and lipoxygenase (LOX). By reducing the production of inflammatory mediators like prostaglandin E2 (PGE2) and leukotrienes, they can alleviate inflammatory responses. This makes them potentially beneficial for conditions such as arthritis.

 

2. Proanthocyanidins

 

• Chemical Structure and Property: Proanthocyanidins are polymers of flavan - 3 - ol units. They have a complex structure and are a type of condensed tannin. In blackcurrant extracts, they contribute to the astringency and antioxidant capacity.
• Main Functions:
  • Powerful Antioxidant: Proanthocyanidins are among the most potent natural antioxidants. They can neutralize a wide range of free radicals more effectively than many other antioxidants. Their antioxidant effect is long - lasting as they can form stable radical - scavenging intermediates. This helps in protecting various tissues and organs from oxidative damage.
  • Cardiovascular Health: Proanthocyanidins can lower blood pressure by inhibiting the activity of angiotensin - I - converting enzyme (ACE). They also reduce blood lipid levels, including cholesterol and triglycerides. Moreover, they prevent platelet aggregation and the formation of atherosclerotic plaques, thus playing a vital role in maintaining a healthy cardiovascular system.
  • Improving Microcirculation: They enhance the permeability and elasticity of microvessels. By improving microcirculation, proanthocyanidins ensure better delivery of nutrients and oxygen to cells and facilitate the removal of metabolic waste products. This can be beneficial for conditions like poor blood circulation in the extremities and varicose veins.

 

3. Vitamin C

 

• Chemical Structure and Property: Vitamin C (ascorbic acid) is a water - soluble vitamin present in blackcurrant extracts. It is an essential nutrient for the human body and is involved in many physiological processes.
• Main Functions:
  • Antioxidant and Immune Support: Vitamin C is a well - known antioxidant that can scavenge free radicals and regenerate other antioxidants such as vitamin E. It plays a crucial role in the immune system. It stimulates the production and function of white blood cells, enhancing the body's defense against infections.
  • Collagen Synthesis: It is essential for the synthesis of collagen, a protein that provides structure to the skin, blood vessels, bones, and other tissues. Adequate vitamin C intake helps maintain the integrity and elasticity of the skin and blood vessels, reducing the risk of bruising and promoting wound healing.
  • Iron Absorption: Vitamin C enhances the absorption of non - heme iron (the form of iron found in plant - based foods) in the intestine. This is beneficial for preventing iron - deficiency anemia.
