以紫红色四季报春花为原料提取色素，并对该色素的稳定性进行研究。结果表明，适宜的提取溶剂为pH＝1的95％乙醇溶液，该色素在382 nm处有最大吸收峰；该色素热稳定性差，有较强的耐光性，耐氧化性，还原性差，在酸性条件下不稳定；金属离子Na＋、K＋、Mg2＋、Zn2＋对色素的影响较小，而Fe3＋对该色素稳定性的影响较大；常用食品添加剂（葡萄糖、蔗糖、可溶性淀粉和柠檬酸）对该色素色泽无不良影响。

Pigment is extracted from purple primrose seasons as raw material,and its stability was studied.The results showed that the 95% ethanol solution with pH=1 was a better extraction solvent,the pigment had maximum absorption peak at 382 nm;the pigment had good light resistance,bad reduction and oxidation resistance,and was unstable under acid condition ;The metal ions Na+、K+、Mg2+、Zn2+have less effect on the pigment,but Fe3+has larger effect on the stability of the pigment,while food additives(for example:glucose,sucrose,soluble starch and citric acid),low valence metal ions had no negative effect.
