Objective. Study the influence of pH, heat, time, light, metal ions, oxidants and other substances on the visible light stability of yellow pigment in Chrysanthemum. Methods. use the 75% ethanol as extraction solvent, the absorbance of extraction pigment were measured in the range of 400 520nm. Results: The maximum absorption wavelength of the pigment was 400nm, the wavelength at the absorbance was 0. 580; optimal pH of the pigment stability conditions was ranged from 4 to 6; the pigment was stable to time and heat, but unstable to light; among the oxidants, except for iron and copper ions, other metal particles has little effect on the pigment; the pigment was a salt--sensitive pigment; suitable for the use of acidic and weakly acidic foods. The natural yellow pigment in Chrysanthemum was safe and reliable. It had great development and utilization value in the rapidly developing food industry.
