摘要:研究了光、热、酸、碱、氧化剂、还原剂、金属离子、蔗糖、Vc等添加剂对用95%乙醇浸提的月见草花黄色素溶液稳定性的影响,结果表明:该色素易溶于95%的乙醇、无水乙醇、丙酮、乙酸乙酯等溶剂.对光、热、碱、氧化剂、金属离子(Na+,Ca2+,Mg2+)及添加剂有一定的稳定性,而对酸、还原剂的稳定性不太好,Cu2+和Fe3+对色素溶液有一定的影响.

关键词: 月见草花, 黄色素, 稳定性

Abstract: This paper studied the stability of yellow pigment from Oenothera biennis L.flower in the following different additive agents:light,heat,acid,sodium hydroxide,hydrogen peroxide,reducer,metal ions,saccharose,Vc,etc.The experimental results show that the pigment can easily dissloved in the solvent of 95% ethanol,pure ethanol,acetone,ether,ethyl ethanoate etc.It has a certain stability toward light,heat,sodium hydroxide,hydrogen peroxide,metal ions(Na+,Mg2+,Ca2+) and food additives ect,however,it has less stability to solutions of hydrochloric acid,sodium sulfite,Cu2+ and Fe3+gave undesirable effects.

Key words: Oenothera biennis L., yellow pigment, stability
