摘要
用一维１Ｈ、１３ＣＮＭＲ谱、ＤＥＰＴ１３ＣＮＭＲ谱、选择性远程ＤＥＰＴ１３ＣＮＭＲ、１Ｈ—１ＨＣＯＳＹ和１３Ｃ－１ＨＣＯＳＹ二维核磁共振技术研究了南海海绵Ｄｙｓｉｄｅａｆｒａｇｉｌｉｓ中的两个倍半萜ｈｅｒｂａｄｙｓｉｄｏｌｉｄｅ（１）和ｆｕｒｏｄｙｓｉｎｉｎｌａｃｔｏｎｅ（２），确认了化学结构．并对其１３ＣＮＭＲ和１ＨＮＭＲ谱进行了归属．药理活性试验表明：１和２具有一定的心血管活性．
The usquiterpenoids herbadysidilide (1) and furodysinin lactonc (2) were isolated from the South China Sea sponge Dysidea fragilis. Their structures were elucidated by 1H, 13C NMR, selective long - range DEPT 13C NMR, 1H-1H COSY and 13C -1H COSY spectroscopy. The 1H and 13C NMR data off and 2 were assigned. The bioactivities of 1 and 2 were also studied.
