Título: | Polysaccharides from the cell walls of pineapple fruit |
Autor: | Bartolome, A. P.; Rupérez Antón, Pilar CSIC ORCID ; Prieto Orzanco, Alicia CSIC ORCID | Fecha de publicación: | 1995 | Editor: | American Chemical Society | Citación: | Journal of Agricultural and Food Chemistry 43: 608- 612 (1995) | Resumen: | Cell wall material from pineapple fruit was obtained and sequentially extracted with 50 mM NaOH at 2°C, 1 M KOH at 2 and 20°C, and 4 M KOH at 20°C. From the 4 M KOH-soluble fraction, a >neutral> polysaccharide and an acidic one were isolated by chloride anion exchange chromatography. The >neutral> fraction was composed of xylose, arabinose, glucose, galactose, and minor quantities of mannose. The infrared spectra showed an absorption band at 900 cm-1 of β-linked polysaccharides. The methylation analysis revealed the main glycosidic linkages of the >neutral> polysaccharide: 1,4-linked xylose with branching points in C3 and C2, 1,4-linked glucopyranose with branching points in C6, and terminal glucopyranosyl, arabinofuranosyl, and arabino/xylopyranosyl residues. © 1995 American Chemical Society. | URI: | http://hdl.handle.net/10261/101193 | DOI: | 10.1021/jf00051a010 | Identificadores: | doi: 10.1021/jf00051a010 issn: 0021-8561 |
