Lignans from Schisandra propinqua var. propinqua

Chem Pharm Bull (Tokyo). 2007 Aug;55(8):1281-3. doi: 10.1248/cpb.55.1281.

Abstract

Two new dibenzocyclooctadiene lignans angeloyl-(+)-gomisin K(3) (1) and methylisogomisin O (2), together with six known ones, isogomisin O, angeloylisogomisin O, gomisin O, angeloygomisin O, benzoylgomisin O, epigomisin O, and four 1,4-bis(phenyl)-2,3-dimethylbutane type lignans, pregomisin, meso-dihydroguaiaretic acid, isoanwulignan, and sphenanlignan were isolated from the aerial parts of Schisandra propinqua var. propinqua. The structures of 1 and 2 were elucidated by spectroscopic methods including extensive 1D- and 2D-NMR techniques.
