The extraction technology of yellow pigments in Coreopsis basalis was studied by use of single factor test and (L_(16)(4~5)) orthogonal experiment design method in this paper. The experimental results indicated that the optimum conditions were the extraction reagent 65% alcohol with pH 3, twelve times of volume of extraction reagent as large as the weight of Coreopsis basalis and extraction temperature at 50 ℃ for 5 hours.
