The plant pigments constitute a fascinating group of compounds whose constitution has only recently been partially clarified. Roughly speaking, there are two main groups of pigment: the plastids, associated with the protoplasmic structure of plants, and the anthocyanins, generally found in solution in the cell sap. The term “anthocyanin” is derived from the Greek, “antho” signifying flower and “cyan” meaning blue, and was introduced by the botanist Marquart in 1835 to designate the blue pigments of flowers. It has since been extended to include all of the pigments of this group, the anthocyanin pigments being responsible for the innumerable shades of blue, red, violet, mauve, and magenta that are found in nature.
