Isolation and Characterization of an Acidic Xylan from Jojoba (Simmondsia chinensis) Hulls

Abstract

An acidic xylan in the 24% KOH extract of jojoba (Simmondsia chinensis) hulls was isolated and characterized by methylation analysis and enzymatic degradation studies. The results suggested that jojoba hull-acidic xylan had a linear chain of β- (1→4) -D-xylosyl residues in the backbone, about 13% of which were branched at the 0-2 position, with 4-0-methyl-α-D-glucopyranosyluronic acid residues.
