✦ Synopsis

Investigations

on the hemicellulose released from extractive-free, delignified pineapple [Ananas comosus (L.) Merr.] leaf fiber revealed that it consists of (l-+4)linked D-xylopyranosyl residues in the main chain, from which branches of 4-0methyl-D-ducopyranosyluronic acid, D-xylopyranosyl, and L-arabinofuranosyl groups originate from O-2 of the D-xylosyl residues.

Pineapple-fibre holocellulose was extracted with alkaline solutions of increasing concentration to give hemicellulose fractions I-III. Purified fraction I (major component) contained D-xylose, L-arabinose, and 4-0-methyl-D-glucuronic acid in the molar proportions 10:0.6: 1, and an average of -116 su
