| Abstract: | An experiment was conducted to extract red pigment from Hydrangea paniculata by orthogonal design.The optimal extraction conditions were obtained as solid-liquid ratio 1∶20,extraction temperature 80 degrees C,extraction time 6 hours,and extraction solvent 60% alcohol(pH=2).The physical and chemical properties of the red pigment were studied.The red pigment extracted from H.paniculata was very resistant to heat and light and stable under acidic conditions,but it was sensitive to reductants and oxidants.Destructive effects of Cu2+,Fe3+ and Fe2+,unobvious effects of Na+,K+,Ca2+,Zn2+,Mg2+ and Mn2+,and protective effects of carbohydrate and organic acid on the extracted red pigment were observed. |
