β¦ Synopsis
A new sesquiterpene, designated as spironippol, was isolated from the title alga.
The structure, which was determined on the basis of the spectral data and X-ray crystallography,

Laurallene (L), a new brominated cyclic ether having a terminal allene moiety, has been isolated as a main constituent from the marine red alga Laurencia nipponica Yamada (Rhodomelaceae, Rhodophyta) and its structure was determined by its physical and chemical properties.
The absolute configuration of cycloeudesmol, isolated from the red alga Lauren&a nipponica Yamada and Chondria oppositiclada Dawson, is determined by the crystallographic study. In our previous report'), the structure of isocycloeudesmol, C15HZ60, isolated from L. nipponica Yamada, has been proposed
