[Objective] The aim was to study on the effects of polysaccharides extracted from Dendrobinm chryseum Rolfe on the proliferation of mice spleen lymphocytes and peritoneal macrophages. [Method] The mice spleen lymphocytes and peritoneal macrophages were cultured in vitro and treated with or without polysaccharides. The changes in proliferations of these immune cells were detected by MTT. [Result] Medium and high concentrations of polysaccharides could significantly increase the proliferation of mice spleen lymphocytes and peritoneal macrophages, while the low concentration one had no enhancement effect. [Conclusion] Polysaccharides could promote the proliferation of mice spleen lymphocytes and peritoneal macrophages in vitro, indicating that it was able to enhance the immunity of mice.
