Four new 3,4\_dihydroxystyrene dimers (3.4.5, and 9) have been isolated from a marine sponge Jaspis sp. along with the known narains (1 and 2). of which 3-5 induced metamorphosis of ascidmn Halocynthia rofetzi larvae. Structures of these metabolites were elucidated on the basis of spectral data. Bio
