Abstract
A glucosyl-rich pectin, JMMP-3 (Mw, 2.572 × 104 g/mol, O-methyl % = 3.62%), was isolated and purified from the pericarp of the immature fruit of Juglans mandshurica Maxim. (QingLongYi). The structure of JMMP-3 was studied systematically by infrared spectroscopy, monosaccharide compositions, methylation analysis, partial acid hydrolysis, and 1/2D-NMR. The backbone of JMMP-3 possessed a smooth region (→ 4GalA1 →) and a hairy region (→ 4GalA1 → 2Rha1 →) with a molar ratio of 2: 5. The substitution of four characteristic side chains (R1-R4) occurs at C-4 of → 2,4)-α-Rhap-(1→, where R1 is composed of → 5)-α-Araf-(1→, R2 is composed of → 4)-β-Galp-(1 → and β-Galp-(1→, R3 is composed of α-Glcp-(1→, →4)-α-Glcp-(1 → and → 4,6)-α-Glcp-(1→, and R4 is composed of → 5)-α-Araf-(1→, β-Galp-(1→, → 4)-β-Galp-(1→, → 3,4)-β-Galp-(1→, → 4,6)-β-Galp-(1 → and → 2,4)-β-Galp-(1 → . In addition, the antitumor activity of JMMP-3 on HepG2 cells was preliminarily investigated.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 321:117564. [PMID: 38081400 DOI: 10.1016/j.jep.2023.117564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 11/13/2023] [Accepted: 12/05/2023] [Indexed: 12/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polygala tenuifolia is used in a variety of Chinese medicine prescriptions for the classic dementia treatment, and polysaccharide is an important active component in the herb. AIM OF THE STUDY This study investigated the in vivo anti-Alzheimer's disease (AD) activity of the polysaccharide PTPS from Polygala tenuifolia using the senescence-accelerated mouse/prone8 (SAMP8) model and explored its molecular mechanism to lay the foundation for the development of polysaccharide-based anti-AD drugs. MATERIALS AND METHODS The Morris water maze test (MWM)was used to detect changes in the spatial cognitive ability of mice, and Nissl staining was applied to observe the state of neurons in the classic hippocampus. The levels of acetylcholine (ACh) and acetylcholinesterase (AChE) were measured by ELISA. Immunofluorescence was used to reflect β-amyloid (Aβ) levels in brain tissue. Apoptosis was evaluated by TdT-mediated dUTP Nick-End Labeling (TUNEL) method. The status of dendritic branches and spines was observed by Golgi staining. Meanwhile, the expression levels of recombinant human insulin-degrading enzyme (IDE), brain-derived neurotrophic factor (BDNF), tyrosine kinase receptor B (TrkB), extracellular regulated protein kinases (ERK), and cAMP-response element binding protein (CREB) proteins were determined by Western blotting. RESULTS PTPS improves spatial cognitive deficits in AD mice, reduces cellular damage in the CA3 region of the hippocampus, maintains the balance of the cholinergic system, and exerts an anti-AD effect in vivo. The molecular mechanism of its action may be related to the reduction of Aβ deposition as well as the activation of ERK pathway-related proteins with enhanced synaptic plasticity. CONCLUSIONS PTPS is able to exert anti-AD activity in vivo by mitigating Aβ damage and targeting the ERK pathway.

Int J Biol Macromol 2023; 248:125895. [PMID: 37481185 DOI: 10.1016/j.ijbiomac.2023.125895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 06/14/2023] [Accepted: 07/18/2023] [Indexed: 07/24/2023]
Abstract
This study identified two homogeneous acidic polysaccharides from Gardeniae fructus, GJP50-3 and GJP50-4, which exhibited potential immunomodulatory activities in macrophage activation assays, via liquid-chip technology, and in a zebrafish model. Monosaccharide composition analysis and gel permeation chromatography revealed that GJP50-3 and GJP50-4 were composed of Rha, GalA, Glc, Gal, and Ara in specific ratios and had molecular weights of 91.5 kDa and 140.3 kDa, respectively. Based on FT-IR, GC-MS, and NMR analyses, these polysaccharides were identified as typical pectin polysaccharides with methylation degrees of 24.7 % and 21.4 %, respectively. The primary structures of GJP50-3 and GJP50-4 included linear HG domains and branched RG-I domains with arabinans and AG side chains. In vitro, GJP50-3 and GJP50-4 could stimulate NO release and increase the secretion of TNF-α in a RAW 264.7 macrophage model. Luminex liquid suspension chip detection revealed that GJP50-3 significantly promoted the secretion of multiple interleukins [IL-6, IL-9, IL-10, IL-12 (p40), IL-12 (p70), IL-13], TNF-α, and chemokines (G-CSF, GM-CSF, MCP-1 and RANTES). In vivo, these polysaccharides could also increase NO release and neutrophil count in a zebrafish model. These findings suggested that GJP50-3 and GJP50-4 might have the potential to be used as immunomodulators in the food and pharmaceutical industries.

Int J Biol Macromol 2023:125540. [PMID: 37355063 DOI: 10.1016/j.ijbiomac.2023.125540] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 06/06/2023] [Accepted: 06/21/2023] [Indexed: 06/26/2023]
Abstract
Gardenia jasminoides (GJ) is a classic edible medicine in China of which the fruit has been proved to alleviate liver damage. We hypothesized whether polysaccharide in the fruit could have comparable bioactivity. To address this, a novel polysaccharide GJE0.2-2, is purified from the fruit of Gardenia jasminoides. Indeed, GJE0.2-2 may attenuate CCl4-induced liver fibrosis in mice and impede the expression of critical fibrogenesis associated molecules such as α-SMA, FN1, and Collagen I induced by TGF-β in human hepatic stellate LX-2 cells. Mechanism studies suggest that this bioactivity may be implicated in TLR4/NF-κB signaling pathway via directly binding to TLR4. The structure characterization shows that the backbone of this polysaccharide is mainly composed of galacturonic acid with minor rhamnose, branched with galactose and arabinose, galacturonic acid, and esterified hexenuronic acid (HexpA). These findings provide evidence for a novel pectin-linked polysaccharide-based new drug candidate development for liver fibrosis therapy.

Abstract
Polysaccharide is one of the major factors for shaping the gut microbiota. However, bioactivity of polysaccharide isolated from Semiaquilegia adoxoides on human gut microbiota remains unclear. Thus, we hypothesize gut microbes may act on it. Herein, pectin SA02B from the roots of Semiaquilegia adoxoides with molecular weight 69.26 kDa was elucidated. The backbone of SA02B was composed of alternate 1, 2-linked α-Rhap and 1, 4-linked α-GalpA, with branches of terminal (T) -, 1, 4-, 1, 3- and 1, 3, 6-linked β-Galp, T-, 1, 5- and 1, 3, 5-linked α-Araf and T-, 1, 4-linked-β-Xylp substituted at C-4 of 1, 2, 4-linked α-Rhap. Bioactivity screening showed SA02B promoted the growth of Bacteroides spp. which deconstructed it into monosaccharide. Simultaneously, we observed competition might exist between Bacteroides spp. and probiotics. Besides, we found that both Bacteroides spp. and probiotics could generate SCFAs grown on SA02B. Our findings highlight SA02B may deserve as a prebiotic to be explored to benefit the health gut microbiota.

Abstract
Polysaccharides were extracted by hot water and alkali in sequence from Dolichos lablab L. hull, and further purified by ion-exchange and gel columns. Hot water extracted D. lablab hull polysaccharide (DLHP) was rich in glucuronoxylan and pectin, and alkali extracted polysaccharide (DLHAP) mostly embraced glucuronoxylan. The structures of purified glucuronoxylans from DLHP and DLHAP were mainly analyzed by HPAEC-PAD, methylation combined with GC-MS, NMR and SEC-MALLS. DLHP-1 was identified as acetylated glucuronoxylan containing →4)-β-Xylp-(1→ backbone with substitution at O-2 site by α-GlcpA/4-O-methyl-α-GlcpA. The molar ratio of β-Xylp to α-GlcpA was 6.9:1, and acetylation was mainly at O-3 site of β-Xylp with acetylation degree of 21.5%. DLHP-1 and DLHP-2 had similar physicochemical properties, except for molecular weight (Mw). DLHAP-1 was the non-methylated glucuronoxylan almost without acetylation, and it had the molar ratio of β-Xylp to α-GlcpA of 5.6:1. Besides, DLHP-1 (Mw of 20.0 × 103 g mol-1) adopted semi-flexible chain, while DLHAP-1 (Mw of 15.4 × 103 g mol-1) showed flexible chain. These results provided a structural basis for study on polysaccharides from D. lablab hull, which was benefit for understanding biological activities and developing functional food or pharmaceuticals of D. lablab.
