Carminic Acid

( Chem.) A purple-brown friable ma , soluble in alcohol and water, and slightly emetic. It unites with bases to form colored salts and precipitates. It may be obtained by treating the powdered cochineal with ether, to remove the fat, and digesting the insoluble portion in water. Acetate of lead is then added, and a lead-like carminate of lead is precipitated. This must be well washed, decomposed by sulphuretted hydrogen, and the filtered solution evaporated in vacuo, over sulphuric acid.-Chlorine, iodine, and bromine change its color to yellow, and the freed alkalies color the aqueous solution purple. With alum, no precipitate occurs until ammonia is added, when it falls down as a brilliant crimson lake. The alkaline earths give purple precipitates, and with salts of tin a bright crimson solution is obtained.
