Abstract: Yellow pigment was extracted with ethanol and water from Dioscorea zingiberensis. The effects of temperature,time, ratio of raw material and solvent on the extracting of yellow pigment were ascertained. Based on the results of single factor experiments and orthogonal experiments, the best extraction processing parameter was obtained. The yellow pigment purified by solene could be obtained with the yield at 1.42% and the colority more than 16.
