Abstract
Pectic substances from cherry fruits ( Prunus avium) were studied after extraction and purification. They were subjected to β-elimination by heat treatment and depolymerized by endopolygalacturonase from Aspergillus niger. The degraded pectins were fractionated by gel permeation chromatography (Sephadex G-100, Bio-gel P2). The results suggest that the pectic substances largely consist of an α- d-galacturonic backbone interspersed with occasional l-rhamnosyl residues. Neutral sugars as side-chains of varying lengths appear to be concentrated along certain regions of the polymer (‘hairy ) ̊ in contrast to side-chain free (§mooth’) parts.
