Abstract
By availing oneself of solubility with the solvents, α-cellulose, β-cellulose and γ-cellulose were separated from Artemisia Capillaris helocellulose. The quantitative analysis gave the following results.
1. All these celluloses contained lignin, and α-cellulose, especially, had much of them. As their sugar components, glucose, xylose and galactose were detected in α-cellulose, and xylose and galactose in both β-cellulose and γ-cellulose. Glucose in α-cellulose was about 46%, the molecular ratio between xylose and galactose in each cellulose being 4: 1, the same as hemicellulose.
2. In the extracts of each cellulose, by 50% alcohol including 1% NaOH or NaClO2, xylose and galactose were detected as the hydrolysed sugars, their molecular ratio being 4: 1. Xylose combining with lignin was also detected.
3. It was concluded that the hemicellulose was a kind of galactoxylan consisting of four parts of xylose and one part of galactose, at a uniform rate, combining with lignin.
