ANALYSIS OF MIXTURES OF SOME MONO-O-METHYLALDOSES WITH THE COMMON ALDOSES BY G.L.C.-M.S. AFTER ISOPROPYLIDENATION

Article abstract of DOI:10.1016/0008-6215(83)88350-5

The O-isopropylidene derivatives of seven naturally occurring mono-O-methylaldoses have been characterised by g.l.c-m.s.G.l.c conditions have been found under which almost complete separation of the O-methyl sugars and the common aldoses as their O-isopropylidene derivatives can be achieved.This analysis procedure has been applied to the hydrolysates of three polysaccharides that contain O-methyl sugars.
