Abstract: | In addition to the salts described previously (with a sulfated steroid as the anion and the alkaloid salsolinol as the cation), nine other steroidal compounds including three new compounds were isolated from the Far-Eastern starfish Lethasterias nanimensis chelifera collected near the coast of the Onekotan island (Kuril isles). A nonsteroidal compound found in this starfish is (1S,3S)-1-methyl-1,2,3,4-tetrahydro--carboline-3-carboxylic acid. The structures of the isolated compounds were determined by NMR spectroscopy and mass spectrometry. |
