Developments in the Chemistry of the Anthocyanins

Abstract

IT is a remarkable fact that almost the whole range of anthocyanin pigments of flowers, fruits, and blossoms is derived from the three fundamental anthocyanidins, namely, pelargonidin, cyanidin, and delphinidin, by various substitutions in the hydroxyl group. A very extensive survey of the colouring matters of this class conducted during the last two seasons has only served to emphasise the prevalence of the three known types.
