摘　　要：To explore the effects of traditional herbal medicine Ganoderrna tsugae（G, tsugae） on immunomodulatory and antitumor activities, the crude polysaccharides of G. tsugae were purified by filtration, diethylaminoethyl（DEAE） sepharose-fast flow chromatography and sephadex G-100 size-exclusion chromatography. Two main fractions, pro- tein-containing glyeans CSSLP-1 and CSSLP-2, were obtained via the gradient elution. The protein content, molecu- lar weight, and monosaccharide composition of the two fractions were analyzed. Furthermore, the influence of the protein-containing glycans from G. tsugae on the activation of human acute monocytic leukemia cell line（THP-l） and their antitumor activities to the human hepatocellular liver carcinoma cell（HepG-2） in vitro were evaluated. The re- sults indicate that CSSLP-1 and CSSLP-2 could increase the pinocytie activity of THP-1 cells and induce THP-1 cells to produce the eytokines of TNFa and IL-2, significantly. CSSLP-1 and CSSLP-2 also played an inhibiting effect on the cancer cell（HepG-2）. Moreover, the anti-proliferation activity of CSSLP-1 and CSSLP-2 increased with the par- ticipation of TNFa and IL-2 or other antitumor factors induced from THP-1 cells by G. tsugae protein-containing glycan fractions.To explore the effects of traditional herbal medicine Ganoderrna tsugae（G, tsugae） on immunomodulatory and antitumor activities, the crude polysaccharides of G. tsugae were purified by filtration, diethylaminoethyl（DEAE） sepharose-fast flow chromatography and sephadex G-100 size-exclusion chromatography.
