Anthocyanins and anthocyanidins are a large group of natural colours. The colour of most fruits, flowers and berries is made up from a combination of anthocyanins and anthocyanidins. Anthocyanins always contain a carbohydrate molecule, whereas anthocyanidins lack this molecule. The individual compounds are isolated from different plant species. E163(i)-(iii) are mixtures. More on anthocyanins and structure, see here.
