Barsett H, Paulsen BS "Separation, isolation and characterization of acidic polysaccharides from the inner bark of Ulmus glabra Huds." -
Carbohydrate Polymers 17 (1992) 137-144
Pectin type polysaccharides were extracted from the inner bark of Ulmus glabra Huds., using water at 50°C. After redissolving the product by boiling, fractionation into 9 polymers was achieved by a combination of two different ion exchange columns. The three most abundant polymers were isolated and characterized. The polysaccharides appeared to have structural differences. The two fractions Afplc and Bfplc contain galacturonic acid, galactose and rhamnose, while Cfplc in addition contains 3-O-methylgalactose, glucuronic acid and acetyl groups. The backbone of all three polysaccharides consists of 4-linked α-D-galactopyranosyl-uronic acid interspersed with 2-linked α-L-rhamnopyranosyl residues. The side chains on Afplc and Bfplc consist of galactose units attached to C-3 of the rhamnose, while the side chains of Cfplc are mainly linked through C-4 of rhamnose. These include 4-linked 3-O-methylgalactose. After weak acid hydrolysis, 5 acidic oligosaccharides were isolated and characterized.

A representative mucilage, named Hibiscus-mucilage Mo, was isolated from the roots of Hibiscus moscheutos L.; it was homogeneous by ultracentrifugal analysis, electrophoresis, and gel chromatography. Its intrinsic viscosity in aqueous solution was 32.2. It is a partially acetylated, acidic polysaccharide of molecular weight ≈1,900,000, and is composed of l-rhamnose: d-galacturonic acid: d-glucuronic acid in approximately equimolar ratio. Methylation of the carboxyl-reduced derivative and partial hydrolysis studies indicated a repeating unit of the following structure [see in the text].

Lerouge P, O'Neill MA, Darvill AG, Albersheim P "Structural characterization of endo-glycanase-generated oligoglycosyl side chains of rhamnogalacturonan I" -
Carbohydrate Research 243 (1993) 359-371
Rhamnogalacturonan I (RG-I) has been isolated from the walls of suspension-cultured sycamore cells (Acer pseudoplatanus), and additional structural features of the polysaccharide were elucidated. Treatment of RG-I with a purified endo-(1→5)-α-L-arabinanase released a series of arabinose-containing oligosaccharides with degrees of polymerization (dp's) between 2 and 20. These oligosaccharides were shown, by glycosyl-linkage composition analysis, to contain terminal, 5-, and (3→5)-linked Araf residues. These results provide evidence that a branched arabinan is attached to the backbone of RG-I. RG-I was freed of 95% of its arabinosyl residues by treating the polysaccharide with a combination of endo-(1→5)-α-L-arabinanase and α-L-arabinosidase. No galacturonic acid was released by these enzymes, which is evidence that the arabinosyl-containing portions of the side chains do not contain galactosyluronic acid residues. The galactose-containing portions of the side chains of RG-I were not fragmented by an endo-(1→4)-β-D-galactanase. However, approximately 85% of the galactose and small amounts of galacturonic acid were released by digestion of arabinose-depleted RG-I with a combination of endo- and exo-β-D-galactanases. The galacturonic acid may have been released by small amounts of an exo-α-galactosyluronidase contaminating the galactanases. Treatment of RG-I with this mixture of endo- and exo-glycanases resulted in a relatively size-homogeneous, almost side chain-free backbone composed of the O-acetylated diglycosyl repeating unit →4)-α-D-GalpA-(1→2)-α-L-Rhap. A combination of 1H NMR spectroscopy and periodate oxidation established that the backbone repeating unit contained a single O-acetyl substituent on C-2 or C-3 of each galactosyluronic acid residue.

Carbohydrate Research 259 (1994) 77-91
Protopectinase-T (PPase-T), isolated from the culture broth of Trametes sanguinea, was able to release pectic substances from sugar beet by degrading rhamnogalacturonan. The smallest polysaccharide (SPS) that can serve as a substrate for PPase-T was prepared from sugar beet pulp by extraction with NaOH and digestion with α-L-arabinofuranosidase, α-L-arabinase, and β-(1→4)-D-galactanase. The reaction products of SPS with PPase-T were isolated by chromatography on DEAE-Toyopearl 650M and Toyopearl HW40-S columns, and analyzed by labeling the reducing ends with [3H]NaBH4 and by 13C NMR spectroscopy. The results indicated that PPase-T cleaved galactopyranosyluronic-rhamnopyranosyl linkages in SPS. Moreover, it was confirmed that the chemical structure of SPS contains a backbone based on units of [→4)-α-D-GalpA-(1→2)-α-L-Rha p-(1→].

Zablackis E, Huang J, Muller B, Darvill AG, Albersheim P "Structure of plant cell wall. 39. Characterization of the cell-wall polysaccharides of Arabidopsis thaliana leaves" -
Plant Physiology 107 (1995) 1129-1138
The cell-wall polysaccharides of Arabidopsis thaliana leaves have been isolated, purified, and characterized. The primary cell walls of all higher plants that have been studied contain cellulose, the three pectic polysaccharides homogalacturonan, rhamnogalacturonan I and rhamnogalacturonan II, the two hemicelluloses xyloglucan and glucuronoarabinoxylan, and structural glycoproteins. The cell walls of Arabidopsis leaves contain each of these components and no others that we could detect, and these cell walls are remarkable in that they are particularly rich in phosphate buffer-soluble polysaccharides (34% of the wall). The pectic polysaccharides of the purified cell walls consist of rhamnogalacturonan I (11%), rhamnogalacturonon II (8%), and homogalacturonan (23%). Xyloglucan (XG) accounts for 20% of the wall, and the oligosaccharide fragments generated from XG by endoglucanase consist of the typical subunits of other higher plant XGs. Glucuronoarabinoxylan (4%), cellulose (14%) and protein (14%) account for the remainder of the wall. Except for the phosphate buffer-soluble pectic polysaccharides, the polysaccharides of Arabidopsis leaf cell walls occur in proportions similar to those of other plants. The structure of the Arabidopsis cell-wall polysaccharides are typical of those of many other plants.

Chemické Zvesti = Chemical Papers [Slovak] 51(5) (1997) 289-294
Three pectic polysaccharide fractions isolated from the methanol-and water-insoluble cell-wall material of the Cistanche deserticola drug by fractional extraction have been investigated using chemical, enzymic, and NMR spectroscopic methods. The pectins differed in the galacturonic acid content which varied between 30 % and 80 %, degree of methyl esterification and acetylation, composition of the neutral carbohydrate components, and molecular properties. They contained homogalacturonan and rhamnogalacturonan RG-I sequences in different proportions, and neutral polysaccharides represented mainly by a highly branched (1→3,5)-α-arabinan. All pectin fractions exhibited immunomodulating properties as indicated by their significant activities in mitogenic and comitogenic tests.

Bioorganicheskaya Khimia = Bioorganic Chemistry [Russian] 24(7) (1998) 483-501
The results of studies on the chemical structure and physiological activity of phanerogam polysaccharides, accumulated within the last two decades, are reviewed. Three types of polysaccharides are considered: rhamnogalacturonans (pectins and related gums and mucilages, type A), acidic arabinogalactans (mainly plant mucilages, gums, and some hemicelluloses, type B), and neutral glucans and heteroglycans (reserve polysaccharides, type C). Various physiological activities of these plant polysaccharides are discussed, with particular emphasis being placed on their immunomodulatory action. The data available on the relationship between chemical structure and physiological activity of plant polysaccharides are considered. Information on the medicinal use of some plants containing physiologically active polysaccharides is presented.
