Abstract: | Hemicelluloses were isolated from pineapple-leaf fibers under different conditions. Study of the properties of these hemicelluloses gave direct evidence of some ester linkages between the hemicellulose and the lignin in this fiber. An aldobiouronic acid was isolated from this fiber hemicellulose, and characterized as 2-O-(4-O-methyl-α-d-glucopyranosyluronic acid)-d-xylose. This indicates that the general nature of the hemicellulose is similar to those of jute and other fiber hemicelluloses. |
