从绿藻总状茎叶藻变种turbinata中分离得到3个新的丁烯内酯，caulerpalide A和一对对映体(+)-caulerpalide B和(-)-caulerpalide B，以及7个已知化合物。所有这些结构都是通过光谱技术确定的。用ECD计算方法确定了茎叶苷A、(+)-茎叶苷B和(-)-茎叶苷B的绝对构型。这是首次从Caulerpa属藻类中分离到丁烯内酯。此外，还对分离得到的9个化合物的抗菌活性进行了评价。
Three new butenolides, caulerpalide A and a pair of enantiomers, (+)-caulerpalide B and (-)-caulerpalide B, together with seven known compounds, have been isolated from the green alga Caulerpa racemosa var. turbinata. All these structures were determined by spectroscopic techniques. The absolute configurations of caulerpalide A, (+)-caulerpalide B and (-)-caulerpalide B were elucidated by the method of ECD calculation. This is the first separation of butenolides from the algae of genus Caulerpa. Additionally, the antibacterial activities of the nine isolated compounds were also evaluated.
