Sulfated trisaccharide moiety

Similar instances, in which analytical data were of prime importance and where no products were isolated, are the oxidations of various di-D-fructose dianhydrides,80 inositols,81 the trisaccharide moiety of the alkaloid solamargine,82 2-O-a-L-fucopyranosyl-L-fucitol derived from fucoidin83 (a polysaccharide sulfate ester), trehalose and neotrehalose,84 maltotetraose,85 D-galactopyranosyl-glyceritol,86 and a 3-pentulose.87... 

Identical sulfated trisaccharide was found in three additional new saponins (2, S, 7). The genin moieties for these saponins correspond to diverse oxidation degrees of saikogenin F. Thus, the epimeric saponins 2 and 5, wth hydroxyl groups at C-29 and C-30, respectively, were also characterised in aerial fractions. A non-sulfated compound 7, holding also a hydroxyl group at C- 29, was detected only in the roots.
