星花绣线菊中的一个新二萜──绣线菊内酯B

SPIRAMILACTONEB,A NEW DITERPENOID FROM SPIRAEA JAPONICA VAR.STELLARIS

从星花绣线菊（Ｓｐｉｒａｅａｊａｐｏｎｉｃａｖａｒ．ｓｔｅｌｌａｒｉｓ）根中得到１个新的Ａｔｉｓｉｎｅ型二萜，命名为绣线菊内酯Ｂ（１），通过光谱分析测定了其结构。此外还得到９个已知化合物，包括１个ａｔｉｓｉｎｅ型二萜──ｓｐｉｒａｍｉｎｏｌ（２）和８个二萜生物碱：ｓｐｉｒａｍｉｎｅＡ，Ｂ，Ｃ，Ｄ，Ｆ，Ｈ，Ｐ，Ｑ．

A new atisine-type diterpenoid named spiramilactone B (1) was islolated from the roots of Spiraeajaponica var. stellaris. Its structure was established by a spectroscopic analysis. In addition, nine known compounds were also obtained, including a atisine-type diterpenoid, spiraminol(2) and eight diterpenoid alkaloids, spiramine A, B, C, D, F, H, P, Q.
