摘 要：
研究大孔树脂分离纯化野酸梅皮色素的条件与方法,并对树脂法所得色素的性质进行检测。结果表明:D101树脂对野酸梅皮色素的吸附效果最佳,以体积分数80%乙醇溶液作洗脱剂洗脱效果较好;野酸梅果皮色素在酸性条件下(pH≤4)较为稳定,耐光、热性较差;金属离子Al3+、Fe3+、Mg2+、Cu2+、Na+对野酸梅果皮色素有不同程度的降色作用。

摘 要：
The purification of pigments from wild plum skins was studied by macroporous resin adsorption.Macroporous resin type D101 showed the best adsorption effect on pigments from wild plum skins among the resins tested,and the best elution results were achieved using 80% ethanol solution.Pigments from wild plum skins were stable under acidic conditions(pH ≤4),but unstable when exposed to light and heat.Al3+,Fe3+,Mg2+,Cu2+ and Na+ had obvious hypochromic effect on the pigments.
