Extraction and Stability of the Yellow Pigment in Chinese Globleflower

The extraction and stability of Yellow pigment in Trollius Chinensis Bge Flower were studied.The extraction conditions were optimized.The Chinese Bge Flower was taken as raw material with the acetone extracted Chinese bgeflower yellow pigment,and the pigment stability had been done more through research.The Chinese bgeflower yellow pigment was easy to dissolve in the acetone,belonging to the fat soluble pigment.The stability of this pigment was good when pH is within 4.0～7.5.It had no better endurance capability against oxidizing agent(H2O2) and reducing agent(Na2SO3).While NaCl and saccharine had little influence on its stability,it did not react too much to various metal ions.The heat performance of the pigment was good when under 60 ℃ and light will destroy the pigment.The stability of the yellow pigment in Chinese globleflower got worse under reduction media,oxidative media and cast light.So it is not conducive to storage.
