[PMID: 38805910 DOI: 10.1016/j.bioorg.2024.107487] [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: 04/25/2024] [Revised: 05/13/2024] [Accepted: 05/20/2024] [Indexed: 05/30/2024]
Abstract
The peel of Trichosanthes kirilowii Maxim, is considered one of the primary sources for Trichosanthis pericarpium in traditional Chinese medicine, exhibiting lipid-lowering properties. The impact on hyperlipidemia mice of the crude polysaccharide from the peel of T. Kirilowii (TRP) was investigated in this study. The findings revealed that TRP exhibited a significant improvement in hepatic lipid deposition. Moreover, it significantly decreased serum levels of TC, TG, and LDL-C, while concurrently increasing HDL-C. 16S rRNA amplicon sequencing technique revealed that TRP group exhibited an increased relative abundance of Actinobacteria, a down-regulated relative abundance of Ruminiclostridium, and an up-regulated relative abundance of Ileibacterium. Therefore, TRP might play a role in anti-hyperlipidemia through regulation of the intestinal milieu and enhancement of microbial equilibrium. Consequently, targeted fractionation of TRP resulted in the isolation of a homogeneous acidic polysaccharide termed TRP-1. The TRP-1 polysaccharide, with an average molecular weight of 1.00 × 104 Da, and was primarily composed of Rha, GlcA, GalA, Glc, Gal and Ara. TRP-1 possessed a backbone consisting of alternating connections between → 6)-α-Galp-(1 → 4)-α-Rhap-(1 → 6)-α-Galp-(2 → 6)-β-Galp-(1 → 6)-α-Galp-(2 → 6)-β-Galp-(1 → units and branched chain containing → 6)-α-Glcp-(1→, 2,4)-β-Glcp-(1, and → 4)-α-GlapA-(1→. Both TRP and TRP-1 exhibited significant disruption of cholesterol micelles, highlighting their potential as lipid-lowering agents that effectively inhibit cholesterol absorption pathways.

Abstract
Platycodon grandiflorus (P. grandiflorus), a traditional Chinese medicinal herb used for both medicine and food, has a long history of treating respiratory infections, bronchitis, pneumonia, and other lung-related diseases. The therapeutic effects of P. grandiflorus are attributed to its chemical components, including polysaccharides. Among these components, Platycodon grandiflorus polysaccharides (PGP) are recognized as one of the most important and abundant active ingredients, exhibiting various biological activities such as prebiotic, antioxidant, antiviral, anticancer, antiangiogenic, and immune regulatory properties. Incorporating the principles of traditional Chinese medicine, carrier concepts, and modern targeted drug delivery technologies, PGP can influence the target sites and therapeutic effects of other drugs while also serving as a drug carrier for targeted and precise treatments. Therefore, it is essential to provide a comprehensive review of the extraction, separation, purification, physicochemical properties, and biological activities of PGP. In the future, by integrating new concepts, technologies, and processes, further references and guidance can be provided for the comprehensive development of PGP. This will contribute to the advancement of P. grandiflorus in various fields such as pharmaceuticals, health products, and food.

Abstract
In this study, water-soluble natural polysaccharides were extracted from the stems of Houttuynia cordata Thunb (HCPS). The optimization of the hot water extraction process using response surface methodology (RSM), and the extraction factors, were analyzed by multiple stepwise regression analysis and Pearson analysis. Then, the structural characterization and biological activity of the HCPS were investigated. The results indicated that the maximum extraction yield (2.43%) of the HCPS was obtained at the optimal condition (extraction temperature for 90 °C, extraction time for 5 h, solid-liquid ratio for 1:30 g/mL). The extraction temperature was determined to be the primary factor influencing the extraction yield. The HCPS molecules had an average molecular weight of 8.854 × 103 kDa and were primarily of mannose (Man), rhamnose (Rha), glucuronic acid (GlcA), galacturonic acid (GalA), glucose (Glc), and xylose (Xyl). In addition, the backbone of the HCPS might consist of →6)-α-d-Glcp-(1→ and →6)-β-d-GalpA-(1→. The HCPS had no triple-helix structure. The scanning electron microscopy (SEM) results showed that the HCPS presented a smooth and uniform appearance, and some sheet and chain structures existed. Moreover, the HCPS exhibited significant anti-oxidant activity and inhibited the activity of α-amylase and α-glucosidase. These findings showed that HCPS might be developed into a potential material for hypoglycemia, and provides a reference for the development of Houttuynia cordata polysaccharide applications in food.

Abstract
The optimum extraction condition for the Saussurea involucrata polysaccharide (SIP) was determined to be a temperature of 80 °C, time 2 h, and a liquid-solid ratio of 30 mL/g with a yield of 11.37 %. An acidic homogenous polysaccharide, namely SIP-II was isolated from Saussurea involucrate through anion exchange and gel permeation column chromatography. The structure of the SIP-II was elucidated through the combination of HPLC, GC-MS, IC, peroxide oxidation, smith degradation, methylation, NMR analysis, it was mainly composed of arabinose, rhamnose, galactose, galacturonic acid, and glucose with the molar ratio of 19.85:20.30: 27.12:11.95:8.69 with a molecular weight of 237,570 Da. The glycosidic linkages of SIP-II mainly composed of →1)-α-L-Rhap-(2→, T-Araf, →1)-β-D-GalpA-(4→, →1)-β-D-Galp-(3,6→, →1)-β-D-Galp-(6→, →1)-α-L-Rhap-(2,4→, T-Galp, and →1)-α-L-Araf-(5→. Meanwhile, the structures were characterized through extensive analysis of UV, FT-IR, SEM-EDX, CD, XRD, and TG. SIP-II possessed a remarkable anti-inflammatory activity by effectively inhibiting the expression of pro-inflammatory cytokines and inflammation-related mediators in LPS-stimulated RAW264.7 macrophages, and the anti-inflammatory response of SIP-II might be attributed to the regulation of the NF-κB, MAPK and JAK/STAT pathways. The results showed that polysaccharides from Saussurea involucrate could be a potential ingredient in the functional food and pharmaceutical industry.

Abstract
Citron (Citrus. medica L.) fruits are commonly utilized in the production of essential oil, therefore, the fruits residues turn out to be industrial byproducts. In the present study, a crude polysaccharide was extracted from citron fruit residues by hot water extraction and precipitation of ethanol (95%), after deproteinization, a major polysaccharide component (CMLP-2) was obtained by gradient ethanol precipitation (20%-80%). The physicochemical properties of CMLP-2 such as surface morphology, functional groups, and thermostability were examined by FT-IR spectroscopy, SEM, and thermogravimetric analysis. Moreover, the chemical structure of CMLP-2 was elucidated that CMLP-2 is an acidic pectic polysaccharide consisting of arabinose (Ara), galacturonic acid (GalA), and rhamnose (Rha) in a molar ratio of 4:2:1 with a molecular weight of 202.18 kDa. CMLP-2 is a novel pectic polysaccharide rich in rhamnogalacturonan I (RG-I). Moreover, rheological tests revealed that CMLP-2 solution is pseudoplastic and temperature resistant. The result could be a good basis for the utilization of Citrus medica L. fruits residues as plant-derived food additive.

Abstract
To investigate the structure of Arthrospira platensis polysaccharide (PAP) (intracellular polysaccharide) and the antioxidant activity of the first component of PAP (PAP-1) on pseudorabies virus (PRV) -infected RAW264.7 cells. The PAP was separated and purified by the Cellulose DE-52 chromatography column and Sephacryl S-200 high-resolution gel column to obtain PAP-1. The antioxidant activity and regulation of PAP-1 on PRV-infected RAW264.7 cells of circRNA-miRNA-mRNA network were investigated by chemical kit, Q-PCR, and ce-RNA seq. The results indicated that the molecular weight (Mw) of PAP-1, which was mainly composed of glucose and eight other monosaccharides, was 1.48 × 106 Da. The main glycosidic bond structure of PAP-1 was →4)-α-D-Glcp-(1→. PAP-1 may be increased the antioxidant capacity by regulating the circRNA-miRNA-mRNA network in PRV-infected RAW264.7 cells. This study provided a scientific foundation for further exploring the antioxidant activity of PAP-1 based on its structure.

Abstract
Nitraria tangutorum Bobr. is suggested to be active in immunoregulation and antioxidation. However, the in vivo bioactivity of N. tangutorum Bobr.-derived polysaccharides (NTP) and their anti-inflammatory activity have not been addressed. In the present study, we extracted and purified polysaccharides from N. tangutorum Bobr. and determined their anti-inflammatory activities in vivo. HPGPC, UHPLC/DAD, and NMR analyses identified that the monosaccharide components of NTP were Man, Rha, GalUA, Glu, Gal, and Ara, with relative contents of 3.52%, 15.08%, 10.00%, 26.73%, 38.08%, and 6.59%, respectively. In mice with lipopolysaccharide (LPS)-induced Acute Lung Injury (ALI), NTP treatment attenuated tissue damage, inhibited the production of inflammatory cytokines, and promoted the anti-oxidative response. The supposed mechanism may be via suppressing the Toll-like receptor 4 (TLR4) signaling pathway. In conclusion, our study suggests a protective role of NTP in LPS-induced ALI by inhibiting inflammatory damage.

Abstract
Coreopsis tinctoria is commonly called Kunlun Chrysanthemum and a plateau plant with tremendous commercial value in functional tea and medicinal applications. In folk medicine, Kunlun Chrysanthemum flower is often used as an adjunctive therapy for diabetes and Alzheimer's disease. To further explore the chemicals responsible for the health benefits of Kunlun Chrysanthemum flowers, three homogeneous oligosaccharides, CT70-1A, CT70-1B and CT70-2 were isolated, and their detailed structures were determined from chemical and spectral analyses. The three oligosaccharides were composed of glucose, mannose, galactose, and arabinose in different ratios. They showed dose-dependent α-amylase and α-glucosidase inhibitory effects. In addition, they showed NO production inhibitory activities in BV2 cells, with IC50 values of 0.23, 0.24 and 0.27 mM, respectively. Taken together, these results suggested that Kunlun Chrysanthemum oligosaccharides might ameliorate hyperglycemia and neuroinflammation, which could prevent the development of diseases such as type 2 diabetes and Alzheimer's disease. This study provides chemical and bioactive perspectives that support the consumption of Kunlun Chrysanthemum flower tea for health benefits.

Abstract
Several strains of microorganism are capable of converting carbohydrates into extracellular polysaccharide. The preset research is a first effort made to optimize extracellular polysaccharide (CRMEP) by Rhodotorula minuta ATCC 10658 using one factor at time and response surface methods. One factor at time was applied in the initial screening of substrates prior to optimization study. Of all the substrates examined, starch as carbon source and defatted soy bean powder as protein source were discovered to be best for CRMEP production. Response surface analysis revealed that 15 g/L starch and 30g/L defatted soy bean powder were the optimal chemical conditions. The model predicted 13.22 g/L for CRMEP, which went along with the experimentally observed result. Purification of CRMEP by anion-exchange column of DEAE-cellulose yielded RMEP. Structural investigation indicated that the main chain of RMEP was composed of (1 → 3) and (1 → 4)-linked mannopyranosyl residues, with branches attached to O-6 of some (1 → 3)-linked mannopyranosyl residues. The branches were composed of Glcp-(1 → residues.

Abstract
Chinese water chestnut peels are a kind of vegetable processing waste containing many active components such as polysaccharides, the structure of which remains unknown. To elucidate the structure of polysaccharides from Chinese water chestnut peels, two polysaccharides named WVP-1 and WVP-2 were isolated. WVP-1 (3.16 kDa) consisted of mannose (1.75 %), glucose (84.69 %), galactose (6.32 %), and arabinose (7.24 %), while WVP-2 (56.97 kDa) was composed of mannose (3.18 %), rhamnose (1.52 %), glucuronic acid (1.42 %), galacturonic acid (4.83 %), glucose (11.51 %), galactose (36.02 %), and arabinose (41.53 %). Linkage and NMR data indicated that WVP-1 was composed mainly of →4)-α-d-Glcp(1→ and a certain proportion of →3)-β-d-Glcp-(1→, including linear and branched polysaccharides simultaneously. WVP-2 was a pectin-like polysaccharide with →4)-α-d-GalpA6Me-(1→ units and the branch points of →3,4)-α-l-Arap-(1→, →3,6)-β-d-Galp-(1→. WVP-2 exhibited stronger potential antioxidant and immunomodulatory activities than WVP-1 in vitro. These results provide a foundation for the further study of polysaccharides from Chinese water chestnut peels.

Abstract
In this study, Polygonum Cillinerve polysaccharide (PCP) was extracted, and characterized by high performance gel permeation chromatography, high performance liquid chromatography, fourier transform infrared spectroscopy, nuclear magnetic resonance and mass spectroscopy. The results showed that PCP was composed of glucose, it was α-D-glucan and the backbone of PCP was consisted of repeating units of (1→4)-α-D-Glucose. In addition, the antioxidant potential of PCP was assessed in vitro. The results showed that PCP had strong hydroxyl radical scavenging ability, some DPPH scavenging ability and good reducing power. Moreover, the results of the enzyme-linked immunosorbent assays showed that PCP at 15.625-0.975 μg/mL could significantly improve the level of superoxide dismutase and glutathione peroxidase, and could significantly decrease the level of myeloperoxidase, malondialdehyde and xanthine oxidase in macrophages. These results indicated that PCP could potentially be developed as a natural antioxidant.

Abstract
In this study, optimization of enzyme-assisted extraction, purification, characterization, and its bioactivities of polysaccharides from Hedyotis corymbosa (HCP) was investigated. It was found that the optimum extraction conditions were 3% of enzyme concentration (X 1 ), 30 of liquid-to-solid ratio (X 2 ), 56°C of extraction temperature (X 3 ), 200W of ultrasonic power (X 4 ), 10 min of extraction time (X 5 ), and 5 of pH value (X 6 ). Under optimum conditions, the experimental yield (4.10 ± 0.16%) was closed to the predicted value (4.02%). The crude HCP was further purified using DEAE-52 and Sephadex G-150 gel column, and a major polysaccharide fraction from HCP, designed as HCP-1a with molecular weight of 33.9 kDa, was obtained. The HCP and HCP-1a were characterized by chemical analysis, FT-IR, and HPLC. For antioxidant activities in vitro, HCP possessed strong hydroxyl radical scavenging, DPPH radical scavenging, and Fe2+ chelating activities. In subsequent immunostimulatory studies, significantly decreased NO, IL-1β, and TNF-α concentrations were observed in both of HCP and HCP-1a treated RAW264.7 cells. Therefore, this study may indicate some insights into the application of polysaccharides from Hedyotis corymbosa as potential natural antioxidants and immunostimulants.
