Rhizome of is an effective medical plant, which has been extensively applied for centuries in migraine and cardiovascular diseases treatment in China. Polysaccharides from this plant have been shown to have interesting bioactivities, but previous studies have only been performed on the neutral polysaccharides. In this study, LCP-I-I, a pectic polysaccharide fraction, was obtained from the 100 °C water extracts of rhizomes and purified by diethylaminethyl (DEAE) sepharose anion exchange chromatography and gel filtration. Monosaccharide analysis and linkage determination in addition to Fourier transform infrared (FT-IR) spectrometer and Nuclear magnetic resonance (NMR) spectrum, indicated that LCP-I-I is a typical pectic polysaccharide, with homo-galacturonan and rhamnogalacturonan type I regions and arabinogalactan type I and type II (AG-I/AG-II) side chains. LCP-I-I exhibited potent complement fixation activity, ICH of 26.3 ± 2.2 µg/mL, and thus has potential as a natural immunomodulator.

Alkaline pectinases are in demand in industrial processes that require the degradation of plant pectins at high pH, for example, removal of pectin stains from fabrics, cutlery, and porcelain; treatment of pectic wastewater; fermentation of coffee, tea, and cocoa; manufacture of poultry and animal feeds, and processing of textiles, and so forth. The present study aimed to (a) screen four alkaliphilic microbial isolates, previously obtained from samples collected around Lake Bogoria (soda lake), Baringo County, Kenya, for alkaline pectinases, and (b) characterize the pectinase-producers. The screening data revealed that all the isolates were pectinase producers, exhibiting catalytic activities that ranged from 1.

Soluble dietary fibers (SDFs) are recognized for their health benefits through their fermentation and gut microbiota modulation. Previous studies focused on individual SDFs without sufficient structural information and a comparative analysis using different SDFs on microbiota composition and function is lacking. The present study aimed to determine key structural features of different SDFs, including soluble resistant starch (SRS), inulin (INU), four structurally diverse pectins (PS1 to PS4), one pectic derivative (PS5) and larch arabinogalactan (AG).

Morinda citrifolia L. (Noni) has been traditionally consumed as both food and medicine, with its polysaccharides (NPs) increasingly recognized for their diverse bioactivities and potential applications in functional foods and therapeutics. This review provides a comprehensive and critical synthesis of recent advances in the extraction, purification, structural characterization, and biological functions of NPs.

The liverwort Marchantia polymorpha has emerged as an important plant model for developmental studies and may become central to elucidate the complex process of cell wall polysaccharide biosynthesis. This study comprehensively analyses the composition and structure of cell wall glycans across eight different M. polymorpha tissue types.
