Abstract
By the same treatment as the previous report, holocellulose was prepared from the leaves and stems of Petasites Japonicus or Osmunda Cinnamomea. From the 5% NaOH-soluble fraction, hemicellulose A, hemicellulose B and hemicellulose C were fractionated by Buston's method, and their chemical compositions were roughly determined on the hydrolysed solution of the hemicelluloses, at first by paper chromatography and then by tests for carbohydrate under usual way. These hemicelluloses consisted of a large amount of xylose and of a small amount of glucose.
