A New Neolignan from Justicia Procumbens

A new neolignan, named (7′S,8′R)-5,3′-dimethoxy-4,4′,9′-trihydroxy-2-8′,9-O-7′-neolignan (1), along with two known compounds, secoisolariciresinol (2) and lariciresinol (3), was isolated from the whole plant of Justicia procumbens L. The structure of 1 was established by spectroscopic methods, and the absolute configuration was determined using circular dichroic (CD) spectra.
