Abstract
Total Pectins Fraction (TPF) was extracted at room temperature from dried cladodes of Opuntia ficus indica. TPF is constituted of three pectic fractions WSP, CSP and ASP, which are made up of 66.6%, 44.3% and 81.1% (w/w) of galacturonic acid, respectively. The antioxidant ability of TPF increased with the concentration increasing. It scavenged hydroxyl radical by 90% and chelated 90% of ferrous ions at 5 g/L. FTIR study was carried out. Strong characteristic absorption peaks at 1,618 cm(-1) assigned to the vibration of COO(-) group of galacturonic acid. In the fingerprint region, we noticed three well-defined peaks at 1054, 1085, and 1,154 cm(-1) characteristic of pectic polysaccharides. TPF are non-gelling pectins. The co-crosslinking of TPF with carrageenan was carried out and the gelling behavior was successfully improved. Thermo-sensitive hydrogel was obtained with 82% of TPF and 18% of carrageenan (w/w).

Abstract
Vesicular packing material (VP) made of clusters of extracted higher plant cells with the intact framework of their cell wall was used so far for permeation chromatography (vesicle chromatography). The objective of this study was to devise a method to entrap dextran in the vesicles. This can provide a means to entrap biocatalysts and secondly, to create aqueous two-phase systems with a stationary dextran phase for liquid-liquid partition chromatography. Dextran of molecular sizes above the separation limit of the plant cell wall cannot permeate into the intracellular space in aqueous medium. However, in hydrophilic organic solvent/water mixtures, dextran molecules can diffuse into the capsules. The removal of the organic solvent leaves the dextran trapped inside. There was an inverse correlation between the percentage of dextran permeating through the cell wall (Pperm) and the concentration of solvent required for dextran precipitation. The increase of permeability is therefore considered to be caused, to a great extent, by the decrease of the effective size of dextran molecules due to decreased solvation. Pperm was inversely correlated to the dielectric constants and the polarities of the solvents and, in the case of protic solvents, the hydrogen-bond acidities. No correlation was found to the hydrogen-bond basicities.
