Antocianina

Natural organic coloring compounds, notably the red coloring of buds and young shoots and the purple and purple-red colors of autumn leaves, which only becomes apparent when the green chlorophyll decomposes with the approach of winter. Anthocyanin pigment for art and other uses is derived from seeds and flowers, for example myrtle berries, blackberries, peonies, delphinium, petunia, and elderberry. These compounds do not form stable insoluble lake pigments. They are water soluble glycosides, red, blue, or violet in color. Examples include pelargonidin, cyanidin, peonidin, delphinidin, petunidin, and malvidin.
