method for producing d-psychosis from d-psychosis borate complex using chromatography and composition containing d-psychosis

摘要

the present application relates to a method for the production of d-psychosis, the method comprising the steps of: placing a composition containing a complex of d-psychosis borate in a chromatography comprising a divalent cation; and separating the composition containing the d-psychosis borate complex into a fraction comprising d-psychosis (i) and a fraction comprising borate (ii).
