In this study, we determined the biochemical composition and biological activities of extracts from three pine species: red pine (RP, Pinus densiflora S et Z), Keumkang pine (KP, Pinus densiflora for. erecta) and sea pine (SP, Pinus thunbergii). The SP extract had the highest levels of moisture, ash, crude protein, and lipids based on the dry weight. The SP extract also had the highest level of polyunsaturated fatty acids (PUFAs). The SP extract had much more β-pinene, β-caryophyllene, and germacrene-D than extracts from the other species. Total phenolic content was the highest in the 100% ethanol extract of SP, and the 50% ethanol extract of SP had the highest DPPH radical scavenging activity. The SP extract had the greatest antimicrobial effect. These results indicate that SP has the greatest potential as a natural antioxidant resource and raw material for cosmetic-goods. http://pubs.sciepub.com/jfnr/5/1/6/jfnr-5-1-6.pdf pine needles biochemical composition nutritive value polyphenol physiological activity
