| | CURRY POWDER: Curcumin |
 | | As thus obtained, curcumin crystallizes in amber-yellow prisms, appearing orange-yellow in reflected light, insoluble in water and diluted acids, sparingly soluble (1 in 2000) in benzene (Daube's solvent, which refuses to dissolve the resins); easily soluble in ether, chloroform, and alcohol; also in diluted alkaline solutions with a striking red-brown, fluorescent color. |
 | | Chemically, curcumin is a substituted aromatic oxyacid, yielding vanillin with weak oxidizers, and protocatechuic acid when fused with caustic potash. |
 | | Curcumin: Confusion exists in present usage of this word; Curcumin is the name for turmeric in many countries; however, expensive products called "Curcumin" are now being sold with the vitamins at health food outlets, and research on curcumin abounds in current medical literature. |
