Tomoda M, Suzuki Y, Satoh N
Plant mucilages. XXIII. Partial hydrolysis of Abelmoschus mucilage M and the structural features of its polysaccharide moiety
Chemical and Pharmaceutical Bulletin 27(7) (1979) 1651-1656
 

Partial acid hydrolysis of Abelmoschus-mucilage M, a representative mucilage isolated from the roots of Abelmoschus manihot MEDICUS, led to the isolation of three oligosaccharides. Analysis of components, reduction and methylation, and partial degradation studies showed that these oligosaccharides are O-α-(D-galactopyranosyluronic acid)-(1→2)-L-rhamnopyranose, O-β-(D-glucopyranosyluronic acid)-(1→3)-O-α-(D-galactopyranosyluronic acid)-(1→2)-L-rhamnopyranose, and O-β-(D-glucopyranosyluronic acid)-(1→3)-O-α-(D-galactopyranosyluronic acid)-(1→2)-O-α-L-rhamnopyranosyl-(1→4)-[O-β-(D-glucopyranosyluronic acid)-(1→3)]-O-α-(D-galactopyranosyluronic acid)-(1→2)-L-rhamnopyranose. The structural features of the polysaccharide moiety in the mucilage are discussed.

Carbon-13 nuclear magnetic resonance spectra of alditol-form oligosaccharides having the fundamental structural units of the Malvaceae plant mucilages and a related polysaccharide
Chemical and Pharmaceutical Bulletin 33 (1985) 5539-5542
 

The carbon-13 nuclear magnetic resonance spectra of five alditol-form oligosaccharides and a polysaccharide having the fundamental structural units of the Malvaceae plant mucilages were measured in aqueous solution and the signals were assigned.

Antidiabetic effect of compounds isolated from plants
Phytomedicine 5(1) (1998) 55-75
 

This review shows some of the compounds isolated and identified from the plants that previously demostrated a hypoglycemic effect. These compounds have been classified in appropiate chemical groups and data are reported on their pharmacological activity, mechanism of action, and other properties. This paper reviews mucilages, glycans, proteins, pectins, flavonoids, steroids and triterpenoids, alkaloids, other nitrogen compounds and miscellaneous substances with hypoglycemic effect.
