During a further and comprehensive phytochemical investigation on the shed trunk barks of the critically endangered plant Abies beshanzuensis, one new (1) and ten known (211) lignans with diverse structures were isolated. On the basis of spectroscopic methods, the new structure was established to be (7S,8R,8′R)-4′-methoxyl-α-conidendrin (1). Among the isolated lignans, (−)-matairesinol (5) and (−)-arctigenin (6) showed significant anti-neuroinflammatory activities by inhibiting the overproduction of nitric oxide in lipopolysaccharide-stimulated murine BV-2 microglial cells, with IC50 values of 11.5 and 19.0 μM, respectively.
