Abstract: The antioxidant properties and contents of phenolic compounds from Picea koraiensis Nakai's cones were examined. Three phenolic compounds parameters (total phenols, flavonoids and proanthocyanidins) and three antioxidant properties parameters (scavenging DPPH radicals, scavenging hydroxyl radicals and reducing power) were measured. The results showed that the extracting solvents significantly effected the contents of total polyphenol, flavonoids, proanthocyanidins and antioxidant activities in Picea koraiensis Nakai's cones.Picea koraiensis Nakai's cones contained high contents of total phenol (88.90±1.37) mg/g and proanthocyanidins (74.26±0.74mg/g) , relatively low flavonoids (47.80±0.86) mg/g. Proanthocyanidins was the major important component of pine polyphenols and played an important role in the antioxidant activities. The chlorogenic acid and catechin identified in Picea koraiensis Nakai's cones extractation might contribute greatly to the high antioxidant activities of the extracts.
