## Abstract Together with five known sesquiterpenes, EtOH extraction of __Laurencia saitoi__ yielded four new compounds, including three sesquiterpenes and one norsesquiterpene derivative. Their structures and relative configurations were elucidated by spectroscopic methods, including 1Dโ and 2DโNM
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
