Polysaccharides in Cyclocarya paliurus (Batal.) Iljinskaja samples of Xiushui country in jiangxi province were obtained from dried Cyclocarya paliurus (Batal.) Iljinskaja powder by hot water extraction. The effects of extraction times, extraction time and the powder-to-water ratio were studied. A L9(33) orthogonal test was carried out by taking extraction times, extraction time and the powder-to-water ratio as the parameters to determine at extraction temperature of 90 ℃. The optimal comditions are as following: extraction three times, extraction time 150 mintues and the powder-to-water ratio 1:8. Under these conditions, the yield of Cyclocarya paliurus (Batal.) Iljinskaja polysaccharides reached 6.54%.
