Carbohydr Polym 2024; 342:122417. [PMID: 39048243 DOI: 10.1016/j.carbpol.2024.122417] [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: 02/21/2024] [Revised: 06/16/2024] [Accepted: 06/17/2024] [Indexed: 07/27/2024]
Abstract
RSA-1 is a polysaccharide obtained from Raphani semen with a relatively clear structure and anti-colon cancer activity. In this study, high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and nuclear magnetic resonance (NMR) spectroscopy were applied to characterise the complex chain structure of RSA-1. Subsequently, the inhibitory effect on colon cancer growth through apoptosis induction in colon cancer cells was explored. The findings indicate that the main chain of RSA-1 consists of →3)-β-D-Galp-(1 → and 3,6)-β-D-Galp-(1 → substituted at C-6 with branched α-L-Araf side chains. RSA-1 disrupts the Bax/Bcl-2 ratio and thus inhibits the viability of colon cancer cells in vitro. Furthermore, it inhibits colon cancer migration by attenuating epithelial-mesenchymal transition. Notably, RSA-1 exhibited negligible impact on the growth of human intestinal epithelial cells within a relevant concentration range. This study establishes a theoretical foundation and provides technical support for the prospective development and application of RSA-1 as a dual-purpose anti-colon cancer drug and functional food.

Bioorg Chem 2024; 153:107790. [PMID: 39241582 DOI: 10.1016/j.bioorg.2024.107790] [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: 07/26/2024] [Revised: 08/30/2024] [Accepted: 09/01/2024] [Indexed: 09/09/2024]
Abstract
Commelina communis L., a functional food and herbal plant in Asia, has been used against obesity, diabetes, and infections for centuries. A growing body of studies has demonstrated that indigestible polysaccharides are significant in obesity management. However, the structures and bioactivities of homogeneous polysaccharides from C. communis remain unclear. This study presented the structural characterization, simulated digestion, and human gut Bacteroides proliferation promotion activity of a novel homogeneous polysaccharide (CCB-3) from C. communis. The results showed that CCB-3 was an arabinoglucuronoxylan, primarily composed of arabinose, galactose, xylose, glucuronic acid (GlcA), and 4-O-methyl GlcA with a molecular weight (Mw) of 58.8 kDa. Following a 6-hour exposure to simulated gastrointestinal fluid, the Mw of CCB-3 remained unchanged, revealing that CCB-3 was an indigestible polysaccharide. Notably, CCB-3 could promote the proliferation of B. thetaiotaomicron, B. ovatus, and B. cellulosilyticus and produce short-chain fatty acids (SCFAs) and 1,2-propanediol. These findings might shed light on the discovery of polysaccharide-based leading compounds from C. communis against obesity.

An arabinan isolated from the antioxidant active fraction of wild blackthorn fruits (Prunus spinosa L.). Carbohydr Res 2023; 523:108730. [PMID: 36543000 DOI: 10.1016/j.carres.2022.108730] [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: 11/14/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022]
Abstract
Despite the many health benefits of wild blackthorn fruits, their use is negligible and little explored. Preliminary results suggest that this fruit is a rich source of natural antioxidants. Antioxidant active fraction, extracted from wild blackthorn fruits by cold water extraction (Cw), was subjected to ion-exchange chromatography, which gave ten fractions after a successive elution with water, sodium chloride and sodium hydroxide solutions. Fraction eluted by water contained an arabinan of a low molecular weight (Mw = 5000). Its chemical and spectroscopic studies have revealed a highly branched structure with backbone composed of 1,5-linked α-l-arabinofuranose residues; about 76% of them are branched dominantly through O3 and much less through O2, however, some arabinose units (∼8%) were fully branched. In addition to terminal α-L-Araf, the presence of β-L-Araf unit was also identified in blackthorn L-arabinan. Antioxidant activity tests of Cw ion exchange fractions revealed significant effects only of fractions eluted with 1 M sodium chloride (6F) and sodium hydroxide (7F) solutions, while phenolic free arabinan did not possess this effect. Phenolic compounds linked via α-l-arabinosyl side chains appear to be responsible for the antioxidant effect of two Cw fractions.

Abstract
Hemicellulose-type polysaccharides were isolated from Campomanesia xanthocarpa fruits by alkaline extraction and submitted to fractionation processes giving rise to eluted (GE-300) and retained (GR-300) fractions. GE-300 presented a mixture of galactoglucomannans (GGM) and glucuronoxylans (MGX), while the GR-300 fraction is composed only of MGX. In this way, the chemical structure of MGX, investigated by 1D 1H, 13C and 2D 1H-13C HSQC, 1H-1H COSY and 1H-13C HMBC NMR spectroscopy, revealed that the chemical structure of polysaccharide is a (4-O-methyl-α-D-glucurono)-D-xylan. Deep and precise NMR chemical shift determination of clean and specific 1H NMR glycosyl units were developed by 1D TOCSY and 1D NOESY analysis. This approach demonstrated unequivocally that 4-O-methyl-α-D-glucopyranosyl uronic acid group is linked to O-2 of a (1 → 4)-β-D-xylan in the main chain. Furthermore, MGX scavenged DPPH radical (0.5 to 1.0 mg mL-1) and was not cytotoxic to human dermal fibroblasts at concentrations up to 1.0 mg mL-1, as demonstrated by neutral red and crystal violet assays, evidencing in vitro biocompatibility. The structure elucidation of GR-300 together with its bioactivity assessment contributed to better understand the chemical characteristics of C. xanthocarpa hemicelluloses and may provide structural basis for future structure-property studies.

Abstract
Polygonatum sibiricum is traditionally used as Chinese medicine for immunity enhancement. Exploration of polysaccharides from Polygonatum species would provide a wider insight into the studies on their chemical structures and function activities. In this study, the alkali-extracted polysaccharide from P. sibiricum (PSP) was isolated and examined. The polysaccharide was firstly isolated by ion-exchange chromatography equipped with DE52 column, followed by isolated through Superdex-200 column. The obtained PSPJWA fraction was a homogenous one with average molecular weight of 141 kDa. The monosaccharide composition was galactose, arabinose and rhamnose in a ratio of 14:4:1. The glycosidic linkages of PSPJWA fraction were indicated to be Araf-(1→, →5)-Araf-(1→, →3,5)-Araf-(1→, Galp-(1→, →4)-Galp-(1→, →4,6)-Galp-(1→ and →2,4)-Rhap-(1→ residue by methylation analysis. NMR and enzymatic studies showed that PSPJWA was a novel arabinogalactan-type structure. PSPJW polysaccharides with different molecular weight and similar chemical structure had different antioxidant activities. Together, P. sibiricum polysaccharide has the potential to be a natural antioxidant.

Abstract
Amomum Villosum Lour. (A. villosum) is a folk medicine that has been used for more than 1300 years. However, study of the polysaccharides of A. villosum is seriously neglected. The objectives of this study are to explore the structural characteristics of polysaccharides from A. villosum (AVPs) and their effects on immune cells. In this study, the acidic polysaccharides (AVPG-1 and AVPG-2) were isolated from AVPs and purified via anion exchange and gel filtration chromatography. The structural characteristics of the polysaccharides were characterized by methylation, HPSEC-MALLS-RID, HPLC, FT-IR, SEM, GC-MS and NMR techniques. AVPG-1 with a molecular weight of 514 kDa had the backbone of → 4)-α-d-Glcp-(1 → 3,4)-β-d-Glcp-(1 → 4)-α-d-Glcp-(1 →. AVPG-2 with a higher molecular weight (14800 kDa) comprised a backbone of → 4)-α-d-Glcp-(1 → 3,6)-β-d-Galp-(1 → 4)-α-d-Glcp-(1 →. RAW 264.7 cells were used to investigate the potential effect of AVPG-1 and AVPG-2 on macrophages, and lipopolysaccharide (LPS) was used as a positive control. The results from bioassays showed that AVPG-2 exhibited stronger immunomodulatory activity than AVPG-1. AVPG-2 significantly induced nitric oxide (NO) production as well as the release of interleukin (IL)-6 and tumor necrosis factor alpha (TNF-α), and upregulated phagocytic capacities of RAW 264.7 cells. Real-time PCR analysis revealed that AVPG-2 was able to turn the polarization of macrophages to the M1 direction. These results suggested that AVPs could be explored as potential immunomodulatory agents of the functional foods or complementary medicine.

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.

Abstract
Two neutral polysaccharides (PSNP-1, 104.7 kDa; PSNP-2, 24.5 kDa) were isolated from the pulp of Pyrus sinkiangensis Yu. by using the combined techniques of ion-exchange and gel permeation chromatography. According to the IR, NMR spectra, monosaccharide composition, and methylation analyses, PSNP-1 was mainly composed of glucose and xylose residues, which form a typical xyloglucan. PSNP-2 contained an arabinan region composed of 1,5-linked Araf residues, a xyloglucan region that was mainly composed of t-, 1,2-linked Xylp, and 1,4-, 1,4,6-linked Glcp residues. PSNP-1 and PSNP-2 could stimulate the cell viability, NO release, and cytokine secretion (IL-6 and TNF-α) of RAW264.7 macrophages at the adosage of 250 μg/mL. It was suggested that PSNP-1 and PSNP-2 may increase macrophage-mediated immunostimulatory activity.
