The optimal technical parameters for extracting pigment from the root of Phellodendron by cellulase assisted microware and its antioxidant activity was studied. The results showed that the optimal conditions were microwave power of 390 W, enzymolysis temperature of 50 ℃, enzymolysis pH of 4.5, microwave time of 120 s, and using water as the extracting solvent. The results of antioxidation showed that pigment extracted from the root of Phellodendron had a certain scavenging effect on free radical of DPPH and hydroxyl radical. The reduction capability was increased with the increase of pigment concentration in experiment. Pigment from the root of Phellodendron was a powerful natural axtioxidant.
