Coloring matter in camillia japonica flowers

<p>The coloring matter in flowers has been used for centuries as a dye. Early man did not know the chemical nature of these coloring matters. Recent investigations have shown that the dark pigments whereas the lighter pigments of flowers are in the anthoxanthin group of pigments. Both of these groups of pigments have a heterocyclic structure. A large number of these pigments have been isolated and identified.</p> <p>The object of this research was to isolate and identity the coloring matter in the Camillia japonica (Belgian red) flowers. This was done by extracting the pigment with methanol and then crystallizing the pigment as a chloride. Color reactions, solubility, spectra, and other physical properties were obtained for this pigment.</p>
