摘　　要：目的 :比较山蓝色素和九头狮子草色素的稳定性。方法 :用紫外分光度法扫描两种色素光谱,确定最大吸收波长。并测定色素液置于光照处、阴暗处,不同的pH、不同的温度、不同的基质中的色素残存率。结果 :九头狮子草红色素液最大吸收波长为580 nm,山蓝红色素液最大吸收波长为585 nm。两种色素液对阳光稳定性差,耐热性好。Na_2S_2O_3、H_2O_2、苯甲酸钠、蔗糖、葡萄糖、淀粉、Na^+、K^+、Ca^(2+)、Zn^(2+)、Mg^(2+)、Mn^(2+)对山蓝色素液和九头狮子草色素液的颜色无不良影响。维生素C、Al^(3+)、Cu^(2+)、Fe^(3+)、Fe^(2+)对两种色素颜色有影响。结论 :此研究为进一步开发红色素资源提供理论依据。Abstact： Objective： to compare the stability of Peristrophe Baphica pigment with that of Peristroph Japoica pigment. Methods：to determine the maximum absorption wavelength by scanning two pigment solution spectrum by ultraviolet spectrophotometry and determine pigment survival rate by placing it in the light, the shadows, different pH, different temperature and different matrix. Results：the maximum absorption wavelength of red pigment from Peristroph Japoica is 580nm and the maximum absorption wavelength of red pigment from Peristrophe Baphica is 585nm. Two kinds of pigment solution display light stability and good heat resistance. Na2S2O3, H2O2, sodium benzoate, sucrose, glucose, starch, Na＋, K＋, Ca2＋, Zn2＋, Mg2＋and Mn2＋exert no adverse effect on the color of pigment solution. Vitamin C, Al3＋, Cu2＋,Fe3＋and Fe2＋have inlfuence on the color of pigment solution. Conclusion：the study provides theoretical basis for further development of red pigment resources.
