Abstract

The invention relates to a process for isolating O-{4,6-dideoxy-4-[[1S-(1,4,6/5)-4,5,6-trihydroxy-3-hydroxymethyl-2-cyclohe xen-1-yl]-amino]-.alpha.-D-glucopyranosyl}-(1.fwdarw.4)-O-.alpha.-D-glucopy ranosyl-(1.fwdarw.4)-D-glucopyranose from culture broths such as are obtained by fermenting micro-organisms of the family Actinoplanaceae, especially of strains of the genus Actinoplanes involving the use of ion exchangers.
