A new polysaccharide was extracted and purified from the roots of Angelica sinensis (Oliv) Diels (ASD). Its composition and linkage was elucidated by selective hydrolysis and GC/MS analysis of its derivatives. The polysaccharide was made of→1) Fru_f(2→and→6) GlC_p (1→as its backbone with highly branched structure. To our best knowledge, this is the first report of the fructose residue in polysaccharides from the roots of the ASD.
