Investigation on the Structure and Immunomodulating Activities of Polysaccharides from the Seeds of Zea Mays / 国际中医中药杂志

ABSTRACT

Objective To investigate the glycosidic linkage and immunomodulating activities of crude polysaccharides from the seeds of Zea mays. Methods Extraction, isolation and purification of polysaccharides were carried out with boiling-water extraction plus resolving deposit repeatedly. The structure was elucidated on basis of physicochemical properties and spectral data, and the biological activities were evaluated by means of Immunopharmacological examination. Results The structure of polysaccharides from the seeds of Z. mays exhibited identical structure with rice bran polysaccharides, i.e., a kind of glucan withα-1,4 andα-1,6 glucosidic bonds as the main frame. Conclusion Polysaccharides was obtained from the seeds of Z. mays for the first time, and it showed significant immunomodulating activity in mice.
