Sugar content and components of Fraction 1 and 2 were investigated by paper chromatography and thin layer chromatography after hydrolysis of the alkaline extracts. Sugar content of Fraction 2 was higher than one of Fraction 1. Main components of Fraction 2 were xylose, arabinose, and glucose. Fraction 1 mainly contained xylose at ratio of 96.4%. Factions 1 and 2 were found to contain xylose also by thin layer chromatography. Fractions land 2 were realized to contain absorption spectrums of OH and CH radicals, and those of ester and ether bonds by infrared spectrum. Infrared absorption spectrums of Fractions 1 and 2 were different but those of hydrates from Fractions 1 and 2 were same. β-Bond absorption showing sugar bond form and ultraviolet absorption of 280nm were found from Fractions 1 and 2 Fractions 1 and 2 were estimated to include structure of bonding sugars to lignin. Negative ninhydrin reaction of Fractions 1and 2 showed absence of amino acids or protein. Fractions 1 and 2 did not bind with bile acids as sodium cholate, sodium deoxycholate and taurochlate.
