摘要：对密蒙花黄色素分别在pH值、温度、光照、蔗糖、葡萄糖、D-果糖、可溶性淀粉、山梨酸钾、Na₂SO₃、H₂O₂、金属离子等存在条件下进行稳定性研究。结果表明：弱酸和中性条件下密蒙花黄色素稳定性较好，随着温度升高和光照时间延长，色素降解越严重；蔗糖、葡萄糖、D-果糖、Ca^2＋、Cu^2＋对密蒙花黄色素均具有保护作用；可溶性淀粉、H₂O₂、K^＋、Na^＋、Sn^2＋、Zn^2＋、Al^3＋、Mg^2＋对密蒙黄色素的影响不明显；山梨酸钾、Na₂SO₃、Fe^3＋、Pb^2＋对密蒙花黄色素具有破坏作用。

Abstract：The experiment studied the stability of the yellow pigment from Buddleja officinalis Maxim in the presence of pH, temperate, light, sucrose, glucose, D-fructose, starch, potassium sorbate, Na₂SO₃, H₂O₂ and metal ions. The result showed that: the stability of the yellow pigment was better under the condition of weak acid and neutral. With the increase of temperature and the extension of light time, the degradation of pigment is more serious. Sucrose, glucose, D-fructose, Ca^2＋, Cu^2＋ have protective effects on the yellow pigment. The effect of starch, H₂O₂, K^＋, Na^＋, Sn^2＋, Zn^2＋, Al^3＋, Mg^2＋ on the pigment was not significant. Potassium sorbate Na₂SO₃, Fe^3＋, Pb^2＋ exert destructive effects on the pigment.
