Abstract

The invention relates to derivatives and reduction products of D-glucopyranosyl-alpha(1.fwdarw.5)-d-arabinonic acid, having the general formula: ##STR1## wherein X is one of the following groups: --COOM, --COOR', CONH.sub.2 or --CH.sub.2 OH, where M is an alkali metal and R' is an alkyl group; and where R is a hydrogen atom or an acyl group. The compounds of formula (I) include compounds in which the arabinonic acid chain is closed in a lactone ring. A method for producing the derivatives and reaction products is described, and uses therefor are also provided.
