摘　　要：采用乙醇水溶液提取栀子黄色素,正交试验分析了料液比、乙醇的浓度、回流温度、回流次数等因素对栀子黄色素提取率的影响。用大孔树脂法分离纯化栀子黄色素,考察了HPD100A、H103等13种大孔树脂对栀子黄色素和栀子甙的吸附性能,确定以HPD100A、H103相结合分离纯化栀子黄色素,可以得到色价>368、OD值<0.24的高品质栀子黄色素。Gardenia yellow was extracted with ethanol and water. The ratio of raw material and solvent, concentration of ethanol, circumfluence temperature and times, impacting on extracting quotiety of gardenia yellow, were ascertained. In the same time, the adsorption characteristic of 13 kinds of resins including HPD100A and H103 for gardenia yellow and geniposide were investigated. Gardenia yellow was purified with HPD100A and H103 and the purified gardenia yellow could be obtained with the colority more than 368 and OD value ess than 0.24.
