AnthocyaninsOverview:It is refined from the vegetable of purple potato, and appears as deep purple powder.It is soluble in water, and provides purple-red shade at pH less than 6, purple to pruple-blue at pH greater than 6.Anthocyanidins bring various benefits for human. Fundamentally, cyanin is a powerful antioxidant, it can protect human from an enzyme called free radicals harmful material damage. Anthocyanins also can enhance hemal flexibility, improve circulation system and enhance skin, inhibit the smoothness of inflammation and allergy, improve joint flexibility. Efficacy for human 1. prevent a variety of diseases associated with free radicals, cluding cancer, heart disease and premature aging and arthritis, 2. prevent stress reaction and smoking-related platelet aggregation to reduce heart disease and stroke occur,3. Enhance the immune system ability to resist carcinogenic substance; 4. Reduce the number of cold and shortening duration, 5. Resistance mutations function thus reduce carcinogenic factor formation; 6. Anti-inflammatory effect, thus can prevent include arthritis and swelling, inflammation, 7. Ease hay fever and other allergies, 8. Enhance arteries and veins and capillaries elastic. 9. Enhance arterial wall, 10. Maintain normal blood cells to help the flexibility of the red blood cell through tiny capillaries, thus enhanced the whole body blood circulation, for different parts of the body's organs and systems brings direct benefits, and strengthen the cell vitality, 11. Relaxation vascular so as to promote the blood flow and prevent on hypertension (fall blood pressure efficacy); 13. Prevent kidney releases of the angiotensin 1-converting enzyme resulting from high blood pressure (another fall blood pressure efficacy); 14. Protect brain cells of the barrier, prevent amyloid beta protein formation, glutamate toxicity and free radical attacks, thereby preventing the alzheimer's, 15. Through the elastase and collagen enzyme inhibition of make skin smooth and rich flexibility, from internal and external to prevent excessive insolation caused by skin damage etc. 16 anthocyanins also has resist radiation effect, anthocyanins color for PH value different can produce change, most anthocyanosides have good light, temperature, PH value, or long-term stability for white-collar in insolation, electric environmental radiation effect of the crowd, anthocyanins but indispensable. 17. Anthocyanidins may promote the cells of the retina of the visual regeneration, prevent myopia, improve eyesight.
