摘　　要：以乙醇为浸提溶剂,对枸杞色素的提取条件进行了单因素试验,并用正交试验对枸杞色素的提取工艺条件进行了优选。枸杞色素的乙醇浸提液紫外可见吸收光谱表明,枸杞色素的特征吸收波长为395 nm,优选出的枸杞色素提取条件为:以1 g∶20 mL的体积比加入浓度为60%的乙醇溶液,80℃下浸提3次,每次2 h。The extraction conditions of Lycium pigment was studied with the ethanol solvent. Based on the single factor tests the optimum extraction conditions were obtained by orthogonal test. The ultraviolet-visible spectrum showed that the absorption peak of the ethanol-pigment-solution exists at 395 nm. The optimum extraction condition was performed at 80℃ with 3 times（each for 2 hours） by the 1 g/20 mL 60 % ethanol solvent.
