This study was conducted to extract and isolate the polysaccharides from buckwheat. Also the sugar composition of the polysaccharides was investigated. The soluble and indigestible polysaccharides were isolated from supernatant and residue after enzyme treatment of raw, roast and steam buckwheat. The yields of low molecular weight soluble polysaccharides(LMS-P: MW10 Kda) were $74.9{\sim}84.2%$ and $5.5{\sim}9.4%$, respectively. The yields of indigestible polysaccharides were low molecular weight insoluble polysaccharides; $0.8{\sim}4.2%$, crude hemicellulose; $3.2{\sim}9.6%$, alcohol insoluble hemicellulose; $0.9{\sim}1.7%$, residue; $2.0{\sim}2.4%$, respectively. The free sugars were detected in the soluble polysaccharides and low molecular weight insoluble polysaccharides but were not detected in the crude hemicellulose, alcohol insoluble hemicellulose and residue. The protein of all fraction were detected and the content was $1.0{\sim}18.9%$. The main sugar of soluble polysaccharides was glucose and the indigestible polysaccharides were composed of glucose, arabinose, rhamnose, xylose, mannose and galactose.
