Abstract: The ultrasonic extraction method was used for extracting yellow pigment from Phellodendron chinense Schneid. bark. The yellow pigment has the maximum absorption at 335-nm wavelength. The optimum extraction solvent is alcohol. The optimum extraction conditions are as follows:concentration of solvent 60%,pH 3 to 7 and extraction temperature 0 ℃. The pigment is quite stable,lightfast,heatproof and hardly affected by common food additives as well as Na+,Cu2+,Mg2+ and Ca2+.
