摘　　要：通过单因素试验和正交实验,确定使用超高压方法提取毛棶色素的最佳提取条件:所用提取液乙醇浓度50%,液料比1:40,保压时间20 min,提取压力200 Mpa。稳定性研究表明,毛株色素具有较好的耐热性:pH严重影响色素的稳定性,中性条件色素较为稳定;毛棶色素对光不敏感;常见食品添加剂对色素稳定性影响较小;Ca"、Mg^(2+)、K^+、Na^+这四种金属离子对毛楝种皮色素影响不大,Al^(3+)、Zn^(2+)、Cu^(2+)、Fe^(2+)这四种金属离子对色素稳定性有较大影响。Through the single factor experiment and orthogonal experiment, we can conclude the most appropriate conditions of using the method of ultrahigh pressure to extract the cornus walteri wanger pigment：the density of ethanol is 50%, the liquid ratio is 1 ： 40, the time is 20 min, the pressure is 200 Mpa. The stability studies have shown that cornus walteri wanger pigment has the capability of heat resistance. The value of pH affects the stability of the pigment seriously, the pigment is stable in the neutral condition relatively. Cornus walteri wanger pigment is not sensitive to the light. Common food additives have little impact on the stability of pigment. Ca2＋, Mg2＋, K＋ and Na＋ metal ions have little impact on the stability of pigment. Al3＋, Zn2＋, Cu2＋ and Fe2＋ metal ions have a great influence on the stability of pigment.
