Abstract:: The extraction and stability of pigment from Magnolia liliflora Desr. were studied.The stability of pigment was studied through measuring the effects of pH,temperature,food additives,reductant-oxidant，metal ion and sunshine on its stability.The results showed that this pigment was unstable in the alkali.Temperature had a few effect on the pigments;H₂O₂could decrease the absorbance of pigment,and Na₂S₂O3 made the pigment extract turbid；Pb2+ and Fe3+ ion had a obvious effect on the stability of pigment.This pigment could be used as a good kind of natural plant pigment because of its good stability and safety.
