Abstract

The O-acetyl groups in Zizyphus-pectin A from the fruits of Zizyphus jujuba Miller Var. Inermis Rehd. Were located at positions 2,3,6 of most of the D-galactopyranosyl residues in galactan side chains. A controlled Smith degradation study supported this conclusion and suggested the presence of continuous branching units in parts of arabinan side chains.
