Eight dibenzocyclooctadiene lignans were isolated from the stems of Schisandra propinqua(Wall.)Hook. f. et Thoms. Their structures were elucidated as acetylgomisin R(1), angeloylgomisin R(2), gomisins A(3), B(4), N(5)...Eight dibenzocyclooctadiene lignans were isolated from the stems of Schisandra propinqua(Wall.)Hook. f. et Thoms. Their structures were elucidated as acetylgomisin R(1), angeloylgomisin R(2), gomisins A(3), B(4), N(5) and O(6), 6 O benzoylgomosin O(7) and schisantherin A(8) by spectral studies. Among them, compound 1 was a new one, compound 2 was discovered in the genus Schisandra for the first time and the others were originally isolated from Schisandra propinqua .展开更多
