anthocyanins from Aronia melanocarpa
Basic Information
- Source: Anthocyanins from Aronia melanocarpa are mainly derived from the fruits of Aronia melanocarpa, also known as chokeberry. It is the fruit of a deciduous shrub belonging to the genus Aronia in the Rosaceae family. The fruits of Aronia melanocarpa are purplish black and are rich in a large amount of nutrients such as anthocyanins.
- Chemical Structure: Anthocyanins from Aronia melanocarpa are mainly composed of glycosides such as delphinidin, cyanidin, petunidin, peonidin, and malvidin. They are a class of flavonoid compounds existing in the form of anthocyanins. These anthocyanins form a variety of different anthocyanin isomers through different glycosylation and acylation modifications.
Physical and Chemical Properties
- Color Characteristics: In an acidic environment, it presents a bright red to purplish red color. As the pH value increases, the color gradually changes to blue and purple. Under alkaline conditions, it may turn blue-green or even yellow. This color-changing property makes anthocyanins from Aronia melanocarpa can be used as a natural pH indicator and colorant in the fields of food and beverages.
- Solubility: It is easily soluble in polar solvents such as water, methanol, and ethanol, slightly soluble in weak polar solvents such as ethyl acetate, and insoluble in non-polar solvents such as n-hexane and petroleum ether. Its good solubility in polar solvents makes it easy to extract from the fruits of Aronia melanocarpa and also convenient for application in various products.
Main Efficacy
- Antioxidant Effect: Anthocyanins from Aronia melanocarpa have a very strong antioxidant activity, and their antioxidant capacity is even higher than that of many common fruits and vegetables. It can scavenge free radicals in the body, such as superoxide anion radicals and hydroxyl radicals, reduce oxidative damage, help prevent diseases related to oxidative stress such as cardiovascular diseases and cancer, and at the same time delay the aging process and maintain the health and vitality of body cells.
- Cardiovascular Health Improvement: It can reduce the levels of cholesterol and triglycerides in the blood, inhibit the oxidation of low-density lipoprotein (LDL), reduce the formation of atherosclerotic plaques, and can also enhance the elasticity of blood vessel walls, lower blood pressure, and improve the function of vascular endothelium, thus providing comprehensive protection for the cardiovascular system and reducing the risk of cardiovascular diseases.
- Anti-inflammatory Effect: It has significant anti-inflammatory effects. It can inhibit the release of inflammatory mediators such as interleukins and tumor necrosis factors, reduce the intensity of the inflammatory response, and alleviate the damage of inflammation to tissues and organs. It has a certain preventive and adjuvant therapeutic effect on chronic inflammatory diseases such as arthritis and enteritis.
- Eye Protection: It can promote the regeneration of rhodopsin in retinal cells, enhance the eyes' sensitivity to light, improve night vision, prevent eye diseases such as retinopathy and macular degeneration, and also has a certain relieving effect on problems such as eye fatigue and dryness caused by long-term use of electronic devices.
- Cognitive Function Improvement: Some studies have shown that anthocyanins from Aronia melanocarpa may protect brain nerve cells through antioxidant and anti-inflammatory effects, promote the growth and repair of nerve cells, and improve the blood circulation of the brain, thus helping to improve memory, attention, and learning ability. It also has potential benefits for preventing neurological diseases such as Alzheimer's disease.
Application Fields
- Food Field: As a natural pigment, it is used for coloring foods such as fruit juices, jams, jellies, candies, and yogurts, giving them an attractive color and increasing consumers' appetite. At the same time, due to its antioxidant properties, it can also be used to extend the shelf life of foods, preventing the oxidative rancidity of oils in foods and the oxidation and deterioration of other components.
- Health Product Field: It is often made into health products in the forms of capsules, tablets, oral liquids, etc., for purposes such as enhancing immunity, antioxidant, anti-aging, protecting the cardiovascular system, and improving eyesight. It is suitable for different groups of people, including the elderly, office workers, and athletes, to meet their health needs.
- Cosmetics Field: Utilizing its antioxidant and anti-inflammatory properties, it is added to skin care products such as facial creams, lotions, serums, and masks. It can help reduce the damage of free radicals to the skin, prevent the formation of wrinkles, fade spots, brighten the skin tone, and enhance the elasticity and luster of the skin, keeping the skin in a young state. It can also be used as a natural colorant and antioxidant in color cosmetics.
- Medical Field: It shows a broad application prospect in medical research. It can be used to develop drugs for the treatment of cardiovascular diseases, eye diseases, inflammatory diseases, neurological diseases, etc. It can also be used as an adjuvant therapeutic drug to improve the antioxidant capacity and immunity of patients and promote the recovery of diseases.
