The MeOH extract of the bark of Picea jezoensis var. jezoensis was found to show scavenging activity for the DPPH radical. Bioassay-guided fractionation led to the isolation of two new flavonostilbenes named jezonocinols A ( 1) and B ( 2) and one nor-flavonostilbene named jezonocinol C ( 3) together with six known phenolic compounds. Their structures were elucidated by spectroscopic methods, and the absolute configurations of jezonocinols A ( 1) and B ( 2) were determined by Mosher's method, CD, and NOESY data.
