The immunomodulatory and antitumor activities of crude polysaccharide （Cwps） and purified polysaccharide（Pwps）extraeted from Chinese white wax scale were investigated in vivo and in vitro. The immunomodulatory effect of Cwps and Pwps were evaluated by carbon particle clearance index, thymus index and spleen index in cyclophosphamide-induced immunosuppressed mice. The inhibition rates of Chinese white wax scale polysaccharide on sarcoma 180 tumor in vivo and human leukemia, lung cancer, gastric cancer and hepatoma cell lines in vitro were observed. The results showed that both the Cwps and Pwps could increase phagocytic index significantly, but had no influence on thymus index and spleen index. The growth of S180 cell was significantly inhibited by Cwps in vivo, but both Cwps and Pwps didn＇ t exhibited direct cytotoxic activities for four kinds tested tumor cells in vitro. The result indicated that antitumor properties of Chinese w
