Abstract: Common varieties of pine needles from Heilongjiang province were selected as the research subject,the flavonoids and polyphenols compound were extracted by different solvents,and DPPH free radical scavenging activities were determined.Results showed that the total flavonoids content,total polyphenol content and DPPH free radical scavenging activities of pine needles extracted by ethanol was better than that by water.The contents of bioactive compounds and DPPH free radicals scavenging activities were significant different between different varieties of pine needles,and showed in following order: Pimcs koraiensis> Larix geelinii>Pinus slverstris.

Key words: pine needles, flavonoids, polyphenols, DPPH free radical
