Abstract: This paper uses 95% ethanol for Flower of Indian Dendranthema yellow pigment ultrasonic extraction,in different ultrasonic frequency,extraction temperature and the ratio of material to water,extracting time etc condition of the extraction technology of yellow pigment had studied,and of pigment in different temperature,light,pH,oxidant,reductant,food additives and some metal ion of conditions of stability for research.The results show that the pigment best extraction process for: ultrasonic frequency 45 kHz,extraction temperature for 60℃,ratio of material to water 1:50,extracting time for 50 min.The yellow pigment stability is poor in light,acidic,reductant,sodium benzoate.In heat,alkaline,oxidant,Vc,citric acid,glucose solution stability is high.Its stability to most metal ion is high,but K+,Fe3+and Al3+ can reduce its colour.
