Two new flavones, 5‐hydroxy‐8‐hydroxymethyl‐7,4′‐dimethoxy‐flavone ( 1 ) and 6‐hydroxy‐8‐hydroxymethyl‐7,4′‐dimethoxy‐flavone ( 2 ), together with six known flavones ( 3–8 ), were isolated from the bark of Lindera caudata . The structures of 1–8 were elucidated by spectroscopic methods including extensive 1D and 2D NMR techniques. Compounds 1–8 were evaluated for their anti‐tobacco mosaic virus (anti‐ TMV ) activity. The results showed that Compounds 1 and 2 showed high anti‐ TMV activity with inhibition rates of 31.2 and 28.8%, respectively. These values are close to those of positive control.
