摘　　要：通过正交实验探讨了唐古特白刺红色素的最佳提取工艺并对其稳定性进行了研究。结果表明：在85℃下用1％盐酸．60％乙醇溶液，以1：40的料液比，回流提取2次，每次40min，提取效果最好；白剌红色素对热、光照、碳水化合物、大部分金属离子的稳定性较好，在酸性条件下稳定。本实验为白刺红色素的开发，白刺果实的综合利用提供了理论依据和实用技术。The optimum extracting conditions of red pigment from Nitraria Tangutorun Bobr.were investigated by oorthogonal experiment and the stability of the red pigment was studied in this paper, The results showed that, the best extraction effect was under the conditions of 85℃,1% hydrochloric acid -60% ethanol, 1：40 the ralio,extracting 2 times and 40min for each times;the red pigment was.stable in heat,light,most metal ions,carbohydrate and acid condition.These researches provide academic basis and practical technique for the exploitation of red pigment from Nitraria tangutorun Bobr. and comprehensive use of its fruit.
