From the aerial parts of Schisandra rubriflora ( Franch ) Rehd . et Wils ., four new dibenzocyclooctadiene lignans, methylgomisin R ( 1 ), (+)‐14‐tigloylgomisin K 3 ( 2 ), 12‐demethylwuweilignan I ( 3 ), schisandrene A ( 4 ), together with 13 known lignans, were isolated. The structures of four new compounds were elucidated by spectroscopic methods including extensive 1D‐ and 2D‐NMR techniques.
