The alkali-soluble galactomannan-like oligosaccharides from the seed of Gleditsia triacanthos
Extraction with alkali of the seeds of Gleditsia triacanthos, after exhaustive extraction with water and neutralization of the extracts by dialysis, permits isolation of the 75% ethanol-soluble products. Gel permeation chromatography of these products allows isolation of an homogeneous galactomannan...
