- Abstract
The red alga Laurencia nipponica Yamada (Rhodo- melaceae, Ceramiales) is known to contain several chemical races, each of which is characterized by a particular, major halogenated secondary metabolite. Both field-collected and cultured plants of a population of this species found recently at Shikanoshima Island, Fukuoka Prefecture, southern Japan, produced C15 bromoethers, (3E)-laureatin and (3E)-iso- laureatin, and sesquiterpenoids, 2, 10-dibromo-3- chloro-9-hydroxy-α chamigrene and 2, 10-dibromo-3- chloro-ct-chamigrene. Laurencia nipponica can be referred to as a turther chemical race that is char- acterized by the production of two C[sup15] bromoethers, (3E)-taureatin and (3E)-isolaureatin, and a sesqui- terpenoid, 2,10-dibromo-3-chloro-9-hydroxy-a- chamigrene as major compounds.
