Abstract
(1) The hemicellulose was isolated from the kernel of “Haze” Rhus succedanea L. and its chemical composition was studied.
(2) The amounts of pentosan and uronic acid anhydride in this preparation were 89%, and 8%, respectively, in the organic matter except lignin, the amount of which was about 8%. The molecular ratio of pentosan to uronic acid anhydride was 15:1.
(3) The hydrolysed solution was examined by phenylosazone, cadmium-xylono-bromide, acid potassium saccharate and other tests for carbohydrates. Furthermore, paper partition chromatography by various methods was also examined.
(4) It was concluded that this hemicellulose consisted of a large quantity of xylose and a small quantity of glucuronic acid and no other carbohydrates.
(5) This hemicellulose was nearly insoluble in water and was hydrolysed scarcely by the snail xylanase.
