Poria cocos Wolf is a popular traditional medicinal plant that has invigorating activity. Water-soluble polysaccharides (PCPs) are its main active components. In this study, four different methods were used to extract PCPs, which include hot water extraction (PCP-H), ultrasonic-assisted extraction (PCP-U), enzyme-assisted extraction (PCP-E) and microwave-assisted extraction (PCP-M). Their chemical compositions and structure characterizations were compared. In vitro antioxidant activities were studied on the basis of DPPH radical, hydroxyl radical, reducing power and metal chelating ability. The results showed that PCPs were composed of mannose, glucose, galactose, and arabinose, and had typical IR spectra characteristics of polysaccharides. Compared with other PCPs, PCP-M had lower neutral sugar content, higher mannose content and higher uronic acid content. The molecular weight were determined as PCP-E
