Sesquiterpenes from the red algal genus Laurencia appear to be valuable taxonomic markers and have shown, for various species, strong correlation with morphological data. In the present study, four chamigrane sesquiterpenes (1–4) were isolated from L. filiformis collected in Salvador, Brazil; these compounds have also been reported for L. scoparia. As discussed by various phycologists, Brazilian specimens of L. scoparia should be considered synonymous with L. filiformis.
