Polysaccharides from natural plant products are gaining considerable attention due to their multi-faceted health effects, as well their functional applications in food production. We reported the sequential extraction of mulberry leaf polysaccharides (MLPs) with hot buffer (HBSS), chelating agent (CHSS), dilute alkali (DASS) and concentrated alkali (CASS), in order to obtain polysaccharide frac...

The traditional method of gas chromatography-mass spectrometry for monosaccharide component analysis with pretreatment of acetylation is described with slight modifications and verified in detail in this paper. It was then successfully applied to the quantitative analysis of component monosaccharides in polysaccharides extracted from the pine cones. The results demonstrated that the three pine...

Agaricus bisporus (A. bisporus) is a rich source of polysaccharides with medical and nutraceutical interests; however, the complex structure A. (ABPs) poses challenge to its quality control. This study aims investigate immunomodulatory fractions ABPs further establish control system for detection characterization bioactive ABPs. Two were obtained using gradient alcohol precipitation combined ul...

The rumen bacterial strains Butyrivibrio fibrisolvens Hl7c, Fibrobacter succinogenes S8S, Lachnospira multiparus 4°, Ruminococcus albus 7 and R. flavefaciens FD-l were compared individually and as a five-species mixture with a rumen inoculum for their ability to degrade lucerne (Medicago sativa L.) stem cell wall polysaccharides. Two maturity stages oflucerne (bud and full flower) were utilized...

Abrus cantoniensis (Hance) is a popular Chinese vegetable consumed as a beverage, soup or folk medicine. To fully exploit the potential of the polysaccharide in Abrus cantoniensis, nine polysaccharide fractions of Abrus cantoniensis were isolated and purified (AP-AOH30-1, AP-AOH30-2, AP-AOH80-1, AP-AOH80-2, AP-ACl-1, AP-ACl-2, AP-ACl-3, AP-H and AP-L). Fourier-transform infrared spectroscopy (F...

EXPERIMENTS recently reported led to the conclusion that serum albumin, even when obtained in the crystalline condition, contains considerable amounts of another protein which is removable only with difficulty [Hewitt, 1936]. It would thus appear that material regarded as being reasonably pure and used as the starting point of many investigations was a mixture of different proteins. A clear-cut...

The Malian medicinal plant Biophytum petersianum Klotzsch (Oxalidaceae) is used as a treatment against various types of illnesses related to the immune system, such as joint pains, inflammations, fever, malaria, and wounds. A pectic polysaccharide obtained from a hot water extract of the aerial parts of B. petersianum has previously been reported to consist of arabinogalactans types I and II (A...

Sequential treatments of dewaxed Calamagrostis angustifolia Kom with water (60 oC and 90 oC), 70% ethanol, and 70% ethanol containing 0.2%, 1.0%, 2.0%, 4.0%, and 8.0% NaOH at a solid to liquid ratio of 1:25 (g/mL) at 80 oC for 3 h yielded 36.2% soluble polysaccharides of the dry dewaxed material. The eight polysaccharide fractions obtained were comparatively studied by sugar analysis, GPC, FT-I...

AIM The aim of this objective is to evaluate the antinociceptive and anti-inflammatory potential of sulfated polysaccharide purified fractions isolated from brown seaweed Sargassum wightii and seagrass Halophila ovalis in male Wistar rats. SUBJECTS AND METHODS Crude sulfated polysaccharide from S. wightii and H. ovalis was subjected to anion exchange chromatography, and the chemical compositi...
