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
