Abstract

Vengono descritti alcuni oligosaccaridi ad attività biologica ed il procedimento per la loro preparazione da glicosaminoglicani, anche sovrasolfatati, in particolare da condroitini, dermatati e miscele di glicosaminoglicani a varia composizione mediante reazioni di beta-eliminazione in solventi organici, o anche in solventi acquosi nel caso di GAGS sovrasolfatati, attraverso un processo con o senza isolamento di prodotti intermedi esterificati.
