title: Six trigalactosylceramides from the leech (Hirudo nipponica).
abstract: Six neutral glycosphingolipids were isolated in the pure state from the leech, Hirudo nipponica (Annelida). In contrast to the zwitterionic monogalactosylceramides carrying a choline phosphate group so far obtained, all compounds are non-zwitterionic glycosphingolipids, trigalactosylceramides. Five compounds possess a Ga1 alpha 1-6Ga1 alpha 1-6Ga1 beta 1-Cer core, and one is unique in having a Ga1 alpha 1-6Ga1 beta 1-Cer structure. Their full structures have been determined on the bases of chemical and spectral evidence.
