    Abstract: To deeply explore the pharmacological activities of the Chinese truffle <I>Tuber sinense</I> (CT) in this study, three kinds of the crude polysaccharides from Chinese Truffle <I>Tuber sinense</I> (CTCP) were extracted by the method of water extracting-alcohol precipitating which include Water-soluble Polysaccharide (W-CTCP) and Alkali-soluble Polysaccharides (A-CTCPI, A-CTCPII) and then the polysaccharide content of the CTCP were determined. The antioxidant activities of the CTCPs were evaluated by reducing power, superoxide radical and hydroxyl radical free radical-scavenging assay. As the results, the polysaccharide (W-CTCP, A-CTCPI and A-CTCPII) content was 46.76, 74.05 and 57.68%, respectively. The polysaccharides all exhibited antioxidant activities <I>in vitro</I> and W-CTCP showed the strongest activity. It can be concluded that the polysaccharides extracted from CT should be explored as a potential natural antioxidant agent for use in functional foods or medicine.
