Anthocyanin
Definition
A water-soluble plant pigment belonging to the flavonoid class, present in the cellular vacuoles of many plants, flowers, and fruits (such as blueberries, blackberries, grapes, or red cabbage), responsible for coloring them in intense shades of red, purple, or blue. These compounds alter their color based on the environmental pH and play a major physiological role as powerful antioxidants, protecting plant tissues from ultraviolet radiation and oxidative stress.
