Abstract:

At present, the reports on polysaccharide are very frequent, however the reports on Hazel polysaccharide’s are seldom. Polysaccharide of wild hazelnut research, can improve the scientific utilization of wild plants, to further tap the resources of medicinal plants has important practical significance. The content of polysaccharide from wild-Hazel leaves(PHl)、wild-Hazelnut (PHn) and wild-Hazel leaves＇callus(PHc) were determined by phenol sulfonic spectrophotometry. Mice received respectively with PHl、PHn、Phc (12.5mg/mL) by gavage for ten days. After that, immune organ, the function of macrophages phagocytosis and the content of serolysin in mice were determined and their immunological activity were evaluated. The results showed, the average content of PHl was (2.93±0.06)%, which was the highest, Phc was the second, its content was(2.26±0.01)%, PHn content was the lowest, only(0.40±0.08)%. Among the three polysaccharide, PHn was the strongest on the immunological activity; the second was PHc; PHl had no remarkable effect on immunity.
