    摘要: An antiulcer agent effective on prevention of ulceration and acceleration of healing of ulcers and processes for preparing the same are disclosed. The antiulcer agent comprises rhamnan (a homopolysaccharide), rhamnose or a rhamnose oligomer as an active ingredient. Rhamnan is prepared by separating rhamnan sulfate from rhamnan sulfate-containing algae and desulfurating the rhamnan sulfate. Rhamnan oligomers are prepared by hydrolyzing rhamnan obtained by desulfuration of rhamnan sulfate or by hydrolyzing microbial cells of a Bifidobacterium or polysaccharides separated therefrom.
