Abstract: Persimmon (Diospyros kaki cv. Mopan) peel and persimmon pulp were extracted with distilled water and alcohol. Extracts of persimmon were test for antioxidant activity by DPPH method and ABTS method, and also composition of total phenol, β-carotene, VC were determined. The result showed that both persimmon peel and persimmon pulp have antioxidant activity, free radical scavenging capacity of alcohol extracts are higher than aqueous extracts. The contributions of phenolic compounds andβ-carotene to antioxidant activity were much greater than those of VC. There was a strong correlation (0.96~0.98) between total phenolics,β-carotene and antioxidant activity of persimmon. The content of VC has no direct correlation with antioxidant activity of persimmon.
