Three new diterpenes and 14 known, brominated and non-brominated diterpenes have been isolated from the red alga Laurencia saitoi collected in 'Isoyake areas' in the Sea of Japan. Some of these diterpenes showed significant feeding-deterrent activity against young abalone (Haliotis discus hannai) and young sea urchins (Strongylocentrotus nudus and S. intermedius), thus suggesting that these metabolites provide a chemical defense against marine herbivorous animals in 'Isoyake areas'.
