title: Glycoyessotoxin a, a new yessotoxin derivative from cultures of Protoceratium reticulatum.
abstract: The dinoflagellate Protoceratium reticulatum produces toxins of the yessotoxin group currently included in the diarrhetic shellfish poisoning class. In this paper we report on the isolation and structural elucidation of a 32-arabinoside of yessotoxin, G-YTXA (2), obtained from laboratory cultures of P. reticulatum (strain GG1AM) that possesses a pentose unit, beta-arabinofuranose, as a side chain.
