- Abstract
A total of 38 methanol and water extracts of macroalgal species (18 brown, 14 red, and 6 green) collected from the Korean coast were investigated for their lethality to brine shrimp larvae. Of the solutions tested, methanol extracts of six species (15.79%) showed larvicidal effects against Artemia salina. Aqueous extracts of two species (5.26%) were lethal to A. salina. The brown algae Dictyota dichotoma, Ecklonia kurome, Ishige okamurae, Sargassum sagamianum, and Pachydictyon coriaceum, and the green algae Enteromorpha linza and Ulva pertusa, displayed significant larvicidal activity in 2.5% methanol extracts. None of the methanol extracts of the 14 red algae species tested had larvicidal effects. The brown alga Colpomenia bullosa and the red alga Lomentaria catenata displayed significant larvicidal activity in 2.5% extracts. No larvicidal effects were observed from extracts of green algae. These results offer insight into the larvicidal potential of Korean seaweed extracts.
