从法国布列塔尼罗斯科夫附近的褐藻Bifurcaria bifurcata中分离到了两个新的二萜类:甲酰基eleganolone(1)和bibifuran(2)。通过一维和二维核磁共振谱和质谱(ESI和EI)分析确定了新化合物的结构。甲酰基eleganolone(1)是由eleganolone(4)的羟基甲酰化而得。bibiuran(2)已被鉴定为呋喃4的新衍生物。此外,从该属植物中首次报道了二萜类化合物16-羟基香叶醇(3)。
Two new diterpenoids formyleleganolone (1) and bibifuran (2) were isolated from a sample of the brown alga Bifurcaria bifurcata collected near Roscoff (Brittany, France). The structures of the new compounds were established on the basis of 1D and 2D NMR spectroscopic and mass spectrometric (ESI and EI) analyses. Formyleleganolone (1) is derived from eleganolone (4) by formylation of the hydroxy group. Bibifuran (2) has been identified as a new furan derivative of 4. Additionally, the diterpenoid 16-hydroxygeranylgeraniol (3) is reported for the first time from this species.
