Abstract:

Anthocyanins are naturally occurring compounds that impart color to fruits, flowers, leaves and other plant organs. They are probably the most important group of visible plant pigments besides chlorophyll. Apart from imparting color to plants, anthocyanins also have an array of health-promoting benefits, as they can protect against a variety of oxidants through a various number of mechanisms. This article reviews their biological activities and also presents a comparative study of some analytical methods used in the determination of anthocyanin content in different extracts. The study results revealed that the measurement using the original standard curve method is the best, simplest and the most accurate one among the other examined methods.
