bupleurum krylovianum/carbohydrate

Glycosphingolids and glycoproteins in cell membrane are thought to play important roles in variety biological phenomena. Our interests focused on elucidation of their functions at the molecular level. We are especially interested in organic chemistry and physical chemistry of carbohydrates. Physical

Several pharmacological activities have been observed in pectic polysaccharides which were isolated from Chinese herbs containing Kampo medicines. We found two different bioactive pectic polysaccharides, bupleuran 2IIb and 2IIc, from the roots of Bupleurum falcatum. These bioactive pectic

Binding of glucose oxidase-anti-glucose oxidase complexes (GAG), a model of immune complexes, to macrophages was enhanced by treatment with an acidic pectic polysaccharide, bupleuran 2IIb, from Bupleurum falcatum L. GAG binding to macrophages by bupleuran 2IIb increased in a dose-dependent fashion,

Direct ELISA was performed using normal human sera and human colostrum, to analyse the presence of antibodies which react with pharmacologically active pectic polysaccharides isolated from plants used in traditional Japanese herbal (Kampo) medicine. All sera and colostrum were shown to contain IgM,

Many osteopenic disorders, including a postmenopausal osteoporosis and lytic bone metastasis in breast and prostate cancers, are linked with a hyperosteoclast activity due to increased receptor activator of nuclear factor kappa-B ligand (RANKL) expression in osteoblastic/stromal cells. Therefore,

A new sulfated triterpene glycoside with the sulfate group located in an unusual position in the carbohydrate moiety, was isolated from the MeOH extract of the aerial parts of Bupleurum rigidum. This compound was identified by a combination of chemical degradation and spectral methods as

Radix bupleuri, roots of Bupleurum species, is a widely used traditional Chinese medicine. Here, we compared the root transcriptomes of both Bupleurum chinense DC. and Bupleurum scorzonerifolium Willd. A total of 313 483 and 342 263 high quality expressed sequence tags were obtained, respectively.

The effect of T-cell-independent B cell mitogen, a pectic polysaccharide, bupleuran 2IIc, from a medicinal herb, the roots of Bupleurum falcatum L. on interleukin 6 (IL-6) production of murine B cells and B cell lines was investigated in order to clarify the mechanism of enhanced immunoglobulin (Ig)

Many Chinese herbs and herbal mixtures are fed to domestic animals for their reputed medicinal properties. These herbs could contribute to the intake of essential nutrients and toxic metals, but their composition is mostly unknown. The purpose of this study was to measure major nutrient (crude
