Kumausallene, a new C15-bromoallene has been isolated from the title alga, and its structure was established on the basis of the spectral properties and chemical degradation.
A new halogenated nonterpenoid C15-compound, epilaurallene, has been isolated as a major constituent from the title alga along with several known compounds, and its structure was determined by the spectral and chemical methods. Epilaurallene is an epimer at C-4 of laurallene and was shown to possess S-configuration at C-4.
通过光谱和化学方法确定了一种新的卤代非三萜类 C15 化合物--表月桂烯(epilaurallene)的结构。表月桂烯是月桂烯 C-4 的表聚体,并被证明在 C-4 上具有 S 构型。
