摘　　要：研究了不同溶剂对小檗色素的提取效果,以及不同pH、不同金属离子、氧化剂和还原剂对该色素稳定性的影响。结果表明,小檗色素在40%的乙醇溶液及水中的溶解效果最好;在酸性条件下色素较稳定;铁离子对其有增色作用;氧化剂、还原剂对色素稳定性均有影响,其中以还原剂影响较大。通过对小檗色素理化性质的研究,表明该色素在化妆品、食品、染料、饮料等工业领域有很大的应用前景。This essay focuses on the extraction of Berberis heteropoda pigment with different impregnants, the influences that different pH condition and different mentalion take on the Berberis heteropoda pigment＇s stability, as well as that oxidizer and reducing agent take on its stability. The results indicated that 40% ethanol and water can dissolve Berberis heteropoda pigment better; the pigment is stable in acidic condition; iron ion can increase the absorbency of the pigment; the influences of reducing agent is greater than oxidizer＇s. By the study of the physical and chemicla characters of the pigment, it showed that the pigment has a great practical prospect on things as cosmetic, foodstuff, dyestuff and beverage.
