A new halogenated C15 nonterpenoid with a novel carbon framework, named notoryne, has been isolated from the title alga and its structure was established on the basis of spectroscopic and chemical evidence. In addition, the structure of a rearranged product, whose structure has long remained unsettled, of laurefucin derivative was also determined by spectral and chemical methods. Furthermore, the biogenesis of the halogenated C15 nonterpenoids from L. nipponica collected at warm current region in Hokkaido is also discussed.
