Abstract
The structures and distributions of C25 highly branched isoprenoid (HBI) alkenes (Haslenes) have been determined following isolation from cultures of the diatoms Haslea ostrearia, Haslea crucigera, Haslea pseudostrearia and Haslea saltstonica. The distributions of the HBIs change between Haslea species and also between different cultures of the same species. Large scale culturing of H. ostrearia and H. pseudostrearia has enabled the structures of three new tetra-unsaturated alkenes to be determined by NMR spectroscopy. The structural relationships between different Haslenes together with the potential significance of the biosynthesis of HBIs by the Haslea genus is discussed.Entities:
