Preparative extraction of anthocyanins from plant materials Edyta Dutkiewicz Abstract Anthocyanins are one of the most common groups of dyes which are soluble in water. They are responsible for red, blue and violet colour of flowers, leaves and fruits. The basic structure of anthocyanins is flavylium ion, to which saccharide residues are often added. Anthocyanins stability depends on many factors: pH, temperature, presence of light and oxygen. These compounds have a lot of positive properties: they are antioxidants, they protect plants from UV radiations and give colour to flower petals.
