Studies on the Chemical Structure of the Gum from the Seed of Gleditsia sinensis Lam

It is determined that the gum from the endosperm of Gleditsia sinensis Lam. consists of D-galactose and D-mannose in the proportions of 1:(3.9–4.0) and the chemical structure is in the form of the gums from two other plants G. melanacantha Tang et Wang and G. heterophylla Bunge were determined also and their chemical structures are in the form of
