Galactomannans and arabinans from seeds of Caesalpiniaceae
Phytochemistry 49(3) (1998)

Schizolobium parahybae
(later renamed to: Schizolobium parahyba)
(NCBI TaxID 46664,

Cassia fastuosa
(Ancestor NCBI TaxID 53851,

Taxonomic group: plant / Streptophyta
(Phylum: Streptophyta)
Organ / tissue: seed
The structure was elucidated in this paperPublication DOI: 10.1016/S0031-9422(98)00228-3Journal NLM ID: 0151434Publisher: Elsevier

Schizolobium parahybae and S. amazonicum seeds yielded galactomannans with identical 3.0:1 Man:Gal ratios and with the same D-galactose distribution along the main chain. Although the galactomannan from seeds of Cassia fastuosa showed the same Man:Gal ratio, its line structure differed significantly from that of the two Schizolobium species as shown by the analysis of cligosaccharides (DP 2 to 6) obtained by partial acid hydrolysis. Seed coats of S. parahybae and S. amazonicum furnished similar unusual neutral linear alpha-L-arabinofuranan (1-->5) linked, as determined by methylation analysis, optical rotation and C-13 NMR spectroscopy. On the other hand, C. fastuosa seed coats furnished two acidic arabinans. These results in terms of using galactomannans and arabinans in chemotyping, support the suggestion of Rizzini that S. parahybae and S. amazonicum are not different species.

Structure type: structural motif or average structure
Location inside paper: Abstract
Compound class: galactomannan

Methods: gel filtration, 13C NMR, 1H NMR, methylation, GC, HPLC, GPC, extraction, acetylation, column chromatography, TFA hydrolysis, C13 NMR
Comments, role: structure of Cassia fastuosa galactomannan differs significantly from S. parahybae and S. amazonicum galactomannans, unsubstituted regions along the main chain are less abundant in the galactomannan of C.fastuosa.
