Abstract: Purification of three hemicellulose fractions isolated by fraction extraction of holocellulose obtained from wood of white willow twigs yielded electrophoretically homogeneous fractions of (4-O-methylglucurono)-xylans, possessing common structural features, but differing in molecular and equivalent weights. The molecular weights of the single fractions of (4-O-methylglucurono)- xylans were 8300, 12 600 and 12 500, while the ratio between 4-O-methyl-D-glucuronic acid and D-xylose was found to be 1 6, 1 8 and 1 10, respectively.
