galactomannans from brazilian seeds: characterization of the oligosaccharides produced by mild acid hydrolysis.galactomannans with man:gal ratios ranging from 1.1:1 to 3:1, obtained from the seeds of mimosa scabrella, stryphnodendron barbatiman, schizolobium parahybum and schizolobium amazonicum, were submitted to mild acid hydrolysis. the products were fractionated by gel permeation chromatography on biogel p2 yielding fractions with degrees of polymerization (dp) of 1 to 6. those with dp 2 to 6 from each species were analysed by ion-exchange high-performance liquid chromatography and characterized by 1 ...19957772557
