Our previous study revealed that the antioxidant activity of polysaccharide (coded as FGFP) extracted from Grifola frondosa by enzymolysis treatment was significantly superior than that (coded as GFP) extracted by boiling-water. In this study, one purified polysaccharide fractions (coded as FGFP-11) was obtained from FGFP by purified using DEAE-52 column and Sephacryl S-500HR column. Results in...

Natural antioxidants such as polysaccharides with strong antioxidant activities are used to protect against oxidative damage, yet little is known so far about the antioxidant effects of litchi fruit polysaccharides. In the present study, four different polysaccharide-enriched fractions were isolated from litchi pulp tissue and partially purified by a stepwise method of ethyl alcohol (EtOH) prec...

aqueous (hydrophilic) and chloroform (lipophilic) extracts of nine medicinal plants currently used in traditional medicine, in egypt, to treat some gastrointestinal tract (git) disorders were tested for their gastro-protective effect against the incidence of peptic ulcer. indomethacin-induced ulcer in a rat model was used for this testing. mentha microphylla, brassica oleracea capitata (cabbage...

In the present study ethanol and water extracts of 15 seaweeds, Dictyota dichotoma var. velutricata, Dictyota indica, Iyengaria stellata, Padina pavonia, Sargassum swartzii, Sargassum variegatum, Stoechospermum marginatum, Stokeyia indica, Jolyna laminarioides, Caulerpa taxifolia, Halimeda tuna, Ulva fasciata, Ulva lactuca, Solieria robusta, and Melanothamnus afaqhusainii, were evaluated for th...

1. The C polysaccharide from pneumococci has been fractionated by gel filtration and by chromatography on diethylaminoethyl Sephadex. The results show that this material is composed of fractions ranging in molecular weight from 65,000 to over 200,000. Furthermore it was noted that all fractions contained the same hexosamine and amino acid components, but in markedly different proportions. 2. Wh...

Lycium barbarum and Ganoderma lucidum, highly valued Chinese medicinal fruit and mushroom, have attracted more and more attention because of the antitumour activities they have shown, and polysaccharides are considered their most important functional constituent. Forming new compounds of L. barbarum polysaccharides, isolated from dried L. barbarum fruits, and G. lucidum polysaccharides, derived...

Five soluble polysaccharide fractions were sequentially extracted with water, EDTA, Na2CO3, 4% KOH, and 14% KOH solutions at room temperature for 4 h from cell wall material of rabbiteye blueberry (Vaccinium ashei) fruits, and their physicochemical properties were examined. The sequential treatments yielded a total 36.02% soluble polysaccharides of the dry cell wall material. HPAEC and spectros...

Reduced, S-aminoethylated porcine ribonuclease was subjected to tryptic hydrolysis. A sequence of fractionation steps that included gel filtration and chromatography over SE-Sephadex C-50, Dowex 50-X2, and Dowex l-X2 afforded a series of glycopeptide fractions which were recognized to derive from three separate regions of the molecule. Heterogeneity of the attached polysaccharide chains preclud...
