Abstract
The authors compared the chemical properties of hemicellulose isolated from Artemisia Capillaris holocellulose (I) with that isolated directly as Cu-complex from the leaves of Artemisia Capillaris (II). The following results were obtained.
Treatment with NaClO2 or as Cu-complex was more effective in removing lignin than that with 1% NaOH. By hemicellulose with much lignin, the sugars were extracted more than lignin, but by hemicellulose with a smaller quantity of lignin, the relation was reversed.
Sample I, hemicellulose A, was hydrolysed completely with 2% HCl solution at 100°C in 90 minutes, and sample II in 70 minutes.
Both hemicelluloses were not hydrolyzed by malt-diastase.
Xylose, galactose, xylobiose, xylotriose and the sugars combining with lignin were detected in the extract with NaClO2 by carbon column chromatography.
