Four flavonoids, 5,7,4'-trihydroxy-3,8,-dimethoxy-6-C-methylflavone (1), 5,8,4'-trihydroxy-3,7-dimethoxy-6-C-methylflavone (2), 7-methoxy-6-C-methylkaempferol (3) and kaempferol-7-O-(2″-E-p-coumaroyl)-α-l-arabinofuranoside (4), together with 15 known compounds, were isolated from the twigs and leaves of Picea neoveitchii Mast. Their structures were elucidated on the basis of analyses of spectroscopic data. Compound 4 showed strong anti-fungal activity against Fusarium oxysporum whereas compounds 1-4 were all active against Rhizoctonia solani.
