Quadratic general rotary design of tetra-factor is employed to optimize the extraction of pigment from corn cob on the basis of mono-factor tests with a purple corn cob as raw materials in order to obtain good yield. The results showed that the yield of primary product of the purple corn cob reached availably 6.88% under the condition of 40 ℃ leaching temperature, 60：1 ratio of liquid-to-solid, 60% ethanol volume fraction, 80 mesh particle diameter, and 3 h extraction time. Furthermore, the color value reached 14.
