Crude extracts of pine needle have been used as a health-food and cosmetic-good materials. In this study to screen the bioactivities of water, 50, 100% ethanol extracts from three pine (seapine (Pinus thunbergii), generalpine (Pinus halepensis) kumkangpine (Pinus densiflora for. erecta) which were easily colleted in Gyeongbuk regions of korea. This research was performed to determine the antioxidant, tyrosinase, phenolic contents, general composition (water, crude protein, lipid, ash, fatty acid) of pine needle extracts. Antioxidant activities measured DPPH (1.1-diphenyl-2-picrylhydrazyl) assay. 50% ethanol extract of seapine possessed strong DPPH radical scavenging activity. The ethanol extract of kumkangpine had relatively higer tyrosinase activities than the remaining pines Total phenolic content was the highest in 100% ethanol extract of seapine. Most of the biological activities of pine tree extracts were in the order of seapine >kumkangpine >generalpine. This suggest that seapine have the greatest properly as a natural antioxidant resources and raw material for foods cosmetic-goods.
