[PMID: 39084431 DOI: 10.1016/j.ijbiomac.2024.134303] [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: 04/02/2024] [Revised: 07/23/2024] [Accepted: 07/28/2024] [Indexed: 08/02/2024]
Abstract
Skin damage from sun exposure is a common issue among outdoor workers and is primarily caused by ultraviolet rays. Upon absorption of these rays, the skin will experience inflammation and cell apoptosis. This study explored the concept of 'Combination of medicine and adjuvant' by utilizing Gastrodia elata polysaccharide, a key component of Gastrodia elata Bl., to develop a new hydrogel material. Oxidized Gastrodia elata polysaccharide (OGEP) and carboxymethyl chitosan (CMCS) was use to prepare a biocompatible, biodegradable and self-healing hydrogel OGEP/CMCS (OC). And this hydrogel was further loaded with Gastrodin-containing microspheres (GAS/GEL) to create GAS/GEL/OGEP/CMCS (GGOC) hydrogel. Characterization studies revealed that OC and GGOC hydrogels exhibited favorable mechanical properties, antioxidant activity and biocompatibility. The experiments showed that OC and GGOC hydrogels could regulate mitochondrial membrane potential, prevent mitochondrial breakage, inhibit proinflammatory factors, prevent NF-κB protein activation and regulate apoptosis-related pathways. This study highlighted the application potential of Gastrodia elata polysaccharide as a 'Combination of medicine and adjuvant' and the anti-UVB damage effect of the prepared hydrogel.

[PMID: 38945333 DOI: 10.1016/j.ijbiomac.2024.133459] [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: 12/27/2023] [Revised: 06/24/2024] [Accepted: 06/25/2024] [Indexed: 07/02/2024]
Abstract
A new polysaccharide, named SP40015A01, was obtained from Saposhnikoviae Radix by water extraction, isolation and purification. SP40015A01 (9.7 × 105 Da) is composed of Rhamnose (Rha), Galacturonic acid (GalA), Galactose (Gal), and Arabinose (Ara) with the proportion of 1.6:85.6:5.8:7.6. The backbone of SP40015A01 is composed of 3-α-GalAp, 2-α-GalAp, 2,3-β-GalAp and 2,3-β-Galp, and branched at C3 of 2,3-β-GalAp, C3 of 2,3-β-Galp. Zebrafish experiments were used to explore the immunomodulatory activity of SP40015A01. Results showed that SP40015A01 could significantly improve the neutrophils density of immunocompromised zebrafish and reduce the content of nitric oxide (NO) and interleukin-1β (IL-1β). This study demonstrated that SP40015A01 has significant immunomodulatory activity, which can improve the neutrophils density and reduce inflammatory factor content, suggesting SP40015A01 may be a potential immunomodulator in Saposhnikoviae Radix (SR) for treatment of hypoimmunity related disease. This study supplemented the research on the polysaccharide components in traditional Chinese medicine and provided a scientific explanation for the development and clinical applications of SR.

Molecules 2024; 29:2412. [PMID: 38893285 PMCID: PMC11173772 DOI: 10.3390/molecules29112412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 05/13/2024] [Accepted: 05/16/2024] [Indexed: 06/21/2024] Open
Abstract
In the study, natural deep eutectic solvents (NADESs) were used as alternatives to traditional chemical solvents for the extraction of polyphenols from Elaeagnus angustifolia L. Nine NADESs were tested for the first time and compared with ethanol and water (traditional solvents) regarding the extraction of phenolic compounds from E. angustifolia L. These solvents were particularly effective at extracting polyphenols, whose low water solubility usually requires high amounts of organic solvents. The solvent based on choline chloride and malonic acid provided optimal results and was selected for further optimization. The effects of material-to-liquid ratio, ultrasound time, and ultrasound temperature on the extraction efficiency were studied through single-factor experiments. These parameters were optimized by Box-Behnken design using response surface methodology. The optimal conditions identified were 49.86 g/mL of material-to-liquid ratio, 31.10 min of ultrasound time, and 62.35 °C of ultrasound temperature, resulting in a high yield of 140.30 ± 0.19 mg/g. The results indicated that the NADES extraction technique provided a higher yield than the conventional extraction process. The antioxidant activity of the extract of polyphenols from E. angustifolia L. was determined, and UPLC-IMS-QTOF-MS was used to analyze the phenolic compounds in it. The results revealed that the scavenging ability of 1,1-diphenyl-2-picryl-hydrazil and 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulphonate) extracted by NADES was higher than that of polyphenols extracted by water and ethanol. Furthermore, a total of 24 phenolic compounds were identified in the extract. To the best of our knowledge, this is the first study in which a green and efficient NADES extraction method has been used to extract bioactive polyphenols from E. angustifolia L., which could provide potential value in pharmaceuticals, cosmetics, and food additives.

Abstract
In recent years, Flammulina velutipes (F. velutipes) has attracted consequential attention in various research fields due to its rich composition of proteins, vitamins, amino acids, polysaccharides, and polyphenols. F. velutipes polysaccharides (FVPs) are considered as key bioactive components of F. velutipes, demonstrating multiple physiological activities, including immunomodulatory, anti-inflammatory, and antibacterial properties. Moreover, they offer health benefits such as antioxidant and anti-aging properties, which have exceptionally valuable clinical applications. Polysaccharides derived from different sources exhibit a wide range of biomedical functions and distinct biological activities. The varied biological functions of polysaccharides, coupled with their extensive application in functional foods and clinical applications, have prompted a heightened focus on polysaccharide research. Additionally, the extraction, deproteinization, and purification of FVPs are fundamental to investigate the structure and biological activities of polysaccharides. Therefore, this review provides a comprehensive and systematic overview of the extraction, deproteinization, purification, characterization, and structural elucidation of FVPs. Furthermore, the biological activities and mechanisms of FVPs have been further explored through in vivo and in vitro experiments. This review aims to provide a theoretical foundation and guide future research and development of FVPs.

Abstract
A new polysaccharide, named SP800201 with Mw of 2.17 × 105 g/mol, was isolated from Saposhnikoviae Radix. The monosaccharide composition of SP800201 mainly contained Gal, GalA, Ara, and Rha. SP800201 has a core structure containing GalA as the backbone and side chains consisting of GalA, Gal, Ara and Rha. Cell and zebrafish experiments were used to explore the immunomodulatory activity of SP800201. Results of vitro RAW264.7 cell experiments showed that SP800201 could significantly improve the proliferation and phagocytosis of macrophages, and promote the release of NO, TNF-α, IL-1β, and IL-6. Results of vivo experiments in immunocompromised zebrafish showed that SP800201 could also significantly increase the density of immune cells, the number of macrophages, and reduce NO, TNF-α, IL-1β, and IL-6. The above results showed that the Saposhnikoviae Radix polysaccharide has certain immunomodulatory activity.

Abstract
In this study, a response surface methodology and an artificial neural network coupled with a genetic algorithm (RSM-ANN-GA) was used to predict and estimate the optimized ultrasonic-assisted extraction conditions of Poria cocos. The ingredient yield and antioxidant potential were determined with different independent variables of ethanol concentration (X1; 25-75%), extraction time (X2; 30-50 min), and extraction solution volume (mL) (X3; 20-60 mL). The optimal conditions were predicted by the RSM-ANN-GA model to be 55.53% ethanol concentration for 48.64 min in 60.00 mL solvent for four triterpenoid acids, and 40.49% ethanol concentration for 30.25 min in 20.00 mL solvent for antioxidant activity and total polysaccharide and phenolic contents. The evaluation of the two modeling strategies showed that RSM-ANN-GA provided better predictability and greater accuracy than the response surface methodology for ultrasonic-assisted extraction of P. cocos. These findings provided guidance on efficient extraction of P. cocos and a feasible analysis/modeling optimization process for the extraction of natural products.

Abstract
Elaeagnus angustifolia Linnaeus is a medicinal plant and its fruit has pharmacological activity such as antiinflammatory, antiedema, antinociceptive, and muscle relaxant functions, etc. Two acidic homogeneous polysaccharides (EAP-H-a1 and EAP-H-a2) were isolated from the fruits of Elaeagnus angustifolia L. through DEAE-52 and Sephadex G-75 column chromatography, and the physicochemical, structural properties, and biological activities of the polysaccharides were investigated. Both EAP-H-a1 and EAP-H-a2 were composed of Rha, Ara, Xyl, Glc, and Gal with the molar ratios of 13.7:20.5:23.3:8.8:33.4 and 24.8:19.7:8.2:8.4:38.6, respectively, and with the molecular weights of 705.796 kDa and 439.852 kDa, respectively. The results obtained from Fourier transform infrared spectroscopy (FTIR) confirmed the polysaccharide nature of the isolated substances. Congo red assay confirmed the existence of a triple-helix structure. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis revealed that EAP-H-a1 and EAP-H-a2 had irregular fibrous, filament-like surfaces; and both had crystalline and amorphous structures. Bioactivity analysis showed that the crude polysaccharide, EAP-H-a1, and EAP-H-a2 had clear DPPH and ABTS free radical scavenging activity, and could promote the secretion of NO and the phagocytic activities of RAW 264.7 and THP cells, which showed clear antioxidant and immuno-regulatory activity. These results indicated that Elaeagnus angustifolia L fruit acidic polysaccharides may have potential value in the pharmaceutical and functional food industries.

Abstract
The traditional media used for the fermentation of Lactobacilli always contain carbohydrate polymers, which interfere with the analysis of the exopolysaccharide (EPS) produced by the bacteria. In this investigation, a novel medium formulation that could avoid such interference was successfully developed. The beef extract, yeast extract, and peptone used in this formulation were subjected to the removal of polysaccharides before use. The factors affecting the EPS production were optimized by a single factor test, Plackett-Burman design, and Box-Behnken design. The optimum formula was ascertained as: 7.5 g L-1 yeast extract, 12.5 g L-1 beef extract, 10 g L-1 peptone, 21.23 g L-1 maltose, 5.51 g L-1 yeast nitrogen base, 2 g L-1 K2HPO4, 5 g L-1 anhydrous sodium acetate, 2 g L-1 ammonium citrate, 0.58 g L-1 MgSO4⋅7H2O, 0.25 g L-1 MnSO4⋅H2O, and 1 mL L-1 Tween 80. The initial pH of the medium was 6.5. The optimized conditions for fermentation of the strain to produce EPS were as follows: seed size 1%, culture temperature 37°C, and culture time 20 h. Optimum results showed that EPS yield was 496.64 ± 3.15 mg L-1, being 76.70% higher than that of unoptimized conditions (281.07 ± 5.90 mg L-1). The EPS was mainly comprised of glucose and guluronic acid, with a weight average molecular weight of 19.9 kDa; it was also characterized by Fourier transform infrared spectroscopy and UV analysis. EPS was found to significantly enhance the phagocytic capacity, promote the NO, TNF-α, IL-1β, and IL-6 secretion, and improve mRNA expression of cytokines in RAW 264.7 macrophages, indicating its considerable immunomodulatory activity. Western bolt and immunofluorescence results demonstrated that the EPS was able to increase p65 nuclear translocation in the macrophages, indicating that EPS enhanced immunity via the NF-κB signaling pathway. EPS investigated in this work has potential as an attractive functional food supplement candidate for the hypoimmunity population.

Abstract
An efficient compound enzyme extraction process was developed and optimized to extract the polysaccharide from Erythronium sibiricum bulb via response surface methodology. The polysaccharide E2P was obtained. Then, the preliminary characteristics of E2P were determined via colorimetry and chromatography. Additionally, the immunoregulatory activities of E2P and another polysaccharide (ESBP, extracted using the hot water method) were compared. The optimized extraction results were as follows: temperature (54.56 °C), time (2.52 h), pH (6.53), and enzyme concentration ratio (0.5% cellulase:1.5% amylase). The yield (64.18% ± 2.91%) obtained under the aforementioned conditions was considerably higher than the yield of ESBP (37.25% ± 0.17%). The total sugar, uronic acid, starch, and protein contents of E2P were 81.77% ± 2.84%, 3.31% ± 0.45%, 3.29% ± 0.01%, and 0.24% ± 0.02%, respectively. The HPLC result suggested that the predominant monosaccharides of E2P included glucose, galactose, and arabinose, with a molar ratio of 543.2:1:1.8. The in vitro tests in RAW264.7 cells indicated that ESBP exhibited better immunomodulatory activities than E2P. In particular, ESBP can promote the proliferation, phagocytosis, and cytokine secretion abilities of cytokines, such as nitric oxide, tumor necrosis factor-α, and interleukin (IL)-1β of RAW264.6 cells. By contrast, E2P can only promote phagocytosis ability and the secretion of IL-1β.

Abstract
BACKGROUND Dry skin is a common skin condition caused by reduction of water-holding capacity, which is regulated by skin barrier function. Dry skin can also be a symptom that indicates a more serious diagnosis. There are a number of moisturizers on the market, which play an important role in dermatologic and cosmetic therapies. However, the demand for these products with good and therapeutic efficiency is still growing. AIMS It remains necessary to investigate the effects of Elaeagnus L gum polysaccharides (EAP), which are prepared from gum of Elaeagnus angustifolia L. on the epidermal permeability barrier function and their possible underlying mechanisms. PATIENTS/METHODS EAP were purified, analyzed, and tested on human keratinocyte cell line (HaCaT) and then on the skin in vivo to evaluate their antiinflammatory activities and their impacts on impaired skin barrier function. RESULTS Histological analyses revealed that topical administration with EAP effectively attenuated dryness-like skin condition, including less percutaneous water loss rate, less infiltrate inflammation cells, and less epidermal thickening. Moreover, EAP inhibited the production of various inflammatory mediators and increased AQP-3, FLG, and LOR expression. CONCLUSION Our results indicated that EAP enhances epidermal permeability barrier function, and they can be used as a promising adjuvant agent in skin care cosmetics and in treating some skin disorders characterized by cutaneous inflammation and abnormal barrier function.

Abstract
Fully ripe fruits and mature leaves of Elaeagnus angustifolia were harvested and analyzed by means of analytical and biological tests to better comprehend the chemical composition and therapeutic/nutraceutical potential of this plant. Fruits and leaves were dried and the obtained powders were analyzed to study their color character and (via headspace gas chromatography) describe the chemical profile. Subsequently, they were submitted to a chloroform-methanol extraction, to a hydroalcoholic extraction procedure assisted or not by microwaves, and to an extraction with supercritical CO2, assisted or not by ethanol as the co-solvent, to detect the polyphenolic and the volatile content. The resulting extracts were evaluated in terms of chlorophyll and carotenoid content, polyphenolic content, volatile fraction, total phenolic content, total flavonoid content, antioxidant activity, radical scavenging activity, and enzymatic inhibition activity. The results confirmed the correlation between the chemical composition and the high antioxidant potential of leaf extracts compared to the fruit extracts in terms of the phenolic and pigment content. A promising effect against tyrosinase emerged for all the extracts, suggesting a therapeutic/nutraceutical use for this plant. Conversely, the volatile content from both natural matrices was similar.

Abstract
Natural polysaccharide is a kind of natural macromolecular which can be extracted from
plants, fungi, algae, animals, and bacteria. The monosaccharide compositions and glucosidic bonds of
polysaccharides from different origins vary substantially. Natural polysaccharides have been shown to
possess complex, important and multifaceted biological activities including antitumor, anticoagulant,
antioxidative, antiviral, immunomodulatory, antihyperlipidemic and antihepatotoxic activities. Their
properties are mainly due to their structural characteristics. It is necessary to develop polysaccharide
immunomodulators with potential for preventive or therapeutic action. The present paper summarizes
the structural features, immunostimulatory activity and the immunomodulatory mechanisms of natural
polysaccharides. In particular, it also provides an overview of representative natural polysaccharide
immunomodulators.

Abstract
To investigate the structure and immunomodulatory activity of polysaccharide from Solanum muricatum, a novel acid polysaccharide named SMP-3a was purified from Solanum muricatum pulp through DEAE-52 cellulose column and Sephadex G-200 chromatography. Monosaccharide composition analysis showed that SMP-3a was mainly composed of rhamnose, arabinose, galactose, and galacturonic acid with the molar ratio of 1.09:2.64:1.54:1. The average molecular weight was found to be 227 kDa by high performance gel permeation chromatography (HPGPC). Thermal studies revealed the SMP-3a was a thermally stable polymer. Based on the results of methylation and NMR analysis, the backbone chain of SMP-3a was composed of →2)-α-l-Rhap-(1→, →4)-α-d-GalpA-(1→ and →4)-α-d-Galp-(1→. The side chain was consisted of α-l-Araf-(1→ and →5)-α-l-Araf-(1→. Immunomodulatory assay indicated that SMP-3a could significantly promote the proliferation of macrophages and stimulate the secretion of cytokines, including TNF-α, IL-1β, and IL-6. Our results suggested that SMP-3a could be used as a novel potential immunomodulatory agent in functional food.

Abstract
Narrow-leaved oleaster (Elaeagnus angustifolia) fruit is a kind of natural product used as food and traditional medicine. Narrow-leaved oleaster fruits from different geographical origins vary in chemical and physical properties and differ in their nutritional and commercial values. In this study, near-infrared hyperspectral imaging covering the spectral range of 874–1734 nm was used to identify the geographical origins of dry narrow-leaved oleaster fruits with machine learning methods. Average spectra of each single narrow-leaved oleaster fruit were extracted. Second derivative spectra were used to identify effective wavelengths. Partial least squares discriminant analysis (PLS-DA) and support vector machine (SVM) were used to build discriminant models for geographical origin identification using full spectra and effective wavelengths. In addition, deep convolutional neural network (CNN) models were built using full spectra and effective wavelengths. Good classification performances were obtained by these three models using full spectra and effective wavelengths, with classification accuracy of the calibration, validation, and prediction set all over 90%. Models using effective wavelengths obtained close results to models using full spectra. The performances of the PLS-DA, SVM, and CNN models were close. The overall results illustrated that near-infrared hyperspectral imaging coupled with machine learning could be used to trace geographical origins of dry narrow-leaved oleaster fruits.

Abstract
In the present study, a novel neutral polysaccharide SMP-0b was extracted and purified from the pulp of Solanum muricatum. Monosaccharide composition analysis revealed that SMP-0b was mainly composed of l-arabinose, d-mannose, d-glucose and d-galactose with the molar ratio of 5.31:2.92:42.23:25.38. The weight-average molecular weight and number-average molecular weight of SMP-0b was calculated to be 13.51 kDa and 9.91 kDa respectively through high performance gel permeation chromatography. The structure of SMP-0b was characterized by methylation and NMR analysis. It showed that the backbone chain of SMP-0b was consisted of →4)-β-d-Galp-(1→, →3,6)-β-d-Manp-(1→ and →6)-α-d-Glcp-(1→, and the side chain was composed of α-l-Araf-(1→ and →4)-α-d-Glcp-(1→. In immunomodulation assays in vitro, SMP-0b exhibited good immunomodulatory activity and could significantly stimulate proliferation and NO production of RAW 264.7 macrophage cells. The results suggested that the neutral polysaccharide from Solanum muricatum might have potential as an immunomodulator or supplement in functional food to enhance immunity.

Abstract
In this paper, polyethylene glycol (PEG)-based ultrasonic-assisted enzymatic extraction (UAEE) was employed in polysaccharides extraction from Lonicerae japonica leaves (LJLP). The optimal extraction conditions (extraction time of 33 min, PEG concentration of 30%, and ultrasonic power of 191 W) were obtained by Box-Behnken design (BBD). Under this condition, the LJLP yield was 14.76%. Furthermore, LJLP was identified as a typical heteropolysaccharide considering the main constitutive monosaccharides include galactose (32.3%), glucose (20.9%), and ribose (15.2%). Moreover, LJLP exhibited high total reducing power and considerable scavenging activities on superoxide radicals, in a concentration-dependent manner in vitro. In addition, antioxidant analysis in vivo revealed that for the LJLP-treated mice, the superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) activities, and total antioxidant capacity (TAOC) were significantly increased, while the level of malondialdehyde (MDA) was decreased in both serum and liver.

Abstract
The extraction of Ramulus mori polysaccharides (RMPs) was optimized using response surface methodology (RSM). The optimal process conditions, which gave the highest yield of RMPs (6.25%) were 80 °C, 50 min, and a solid–liquid ratio of 1:40 (g/mL), with the extraction performed twice. The RMPs contained seven monosaccharides, namely, mannose, rhamnose; glucuronic acid, glucose, xylose, galactose, and arabinose, in a 1.36:2.68:0.46:328.17:1.53:21.80:6.16 molar ratio. The glass transition and melting temperatures of RMPs were 83 and 473 °C, respectively. RMPs were α-polysaccharides and had surfaces that resembled a porous sponge, as observed by scanning electron microscopy. RMPs inhibited the proliferation of Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa and showed antioxidant activity (assessed by three different methods), although it was generally weaker than that of vitamin C. RMPs showed anti-inflammatory activity in a concentration-dependent manner. This study provides a basis for exploring the potential uses of RMPs.

Cis-3-O-p-hydroxycinnamoyl Ursolic Acid Induced ROS-Dependent p53-Mediated Mitochondrial Apoptosis in Oral Cancer Cells. Biomol Ther (Seoul) 2019; 27:54-62. [PMID: 30261716 PMCID: PMC6319548 DOI: 10.4062/biomolther.2017.237] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 07/05/2018] [Accepted: 08/08/2018] [Indexed: 11/05/2022] Open
Abstract
Cis-3-O-p-hydroxycinnamoyl ursolic acid (HCUA), a triterpenoid compound, was purified from Elaeagnus oldhamii Maxim. This traditional medicinal plant has been used for treating rheumatoid arthritis and lung disorders as well as for its anti-inflammation and anticancer activities. This study aimed to investigate the anti-proliferative and apoptotic-inducing activities of HCUA in oral cancer cells. HCUA exhibited anti-proliferative activity in oral cancer cell lines (Ca9-22 and SAS cells), but not in normal oral fibroblasts. The inhibitory concentration of HCUA that resulted in 50% viability was 24.0 µM and 17.8 µM for Ca9-22 and SAS cells, respectively. Moreover, HCUA increased the number of cells in the sub-G1 arrest phase and apoptosis in a concentration-dependent manner in both oral cancer cell lines, but not in normal oral fibroblasts. Importantly, HCUA induced p53-mediated transcriptional regulation of pro-apoptotic proteins (Bax, Bak, Bim, Noxa, and PUMA), which are associated with mitochondrial apoptosis in oral cancer cells via the loss of mitochondrial membrane potential. HCUA triggered the production of intracellular reactive oxygen species (ROS) that was ascertained to be involved in HCUA-induced apoptosis by the ROS inhibitors YCG063 and N-acetyl-L-cysteine. As a result, HCUA had potential antitumor activity to oral cancer cells through eliciting ROS-dependent and p53-mediated mitochondrial apoptosis. Overall, HCUA could be applicable for the development of anticancer agents against human oral cancer.

Sulfated Cyclocarya paliurus polysaccharides markedly attenuates inflammation and oxidative damage in lipopolysaccharide-treated macrophage cells and mice. Sci Rep 2017; 7:40402. [PMID: 28094275 PMCID: PMC5240341 DOI: 10.1038/srep40402] [Citation(s) in RCA: 72] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2016] [Accepted: 12/06/2016] [Indexed: 12/22/2022] Open
Abstract
Natural polysaccharides and their modified derivatives are crucial supplements to the prevention of inflammation. This study aimed to evaluate the effect of sulfated modification on the anti-inflammatory and anti-oxidative activities of Cyclocarya paliurus polysaccharides (CP). A sulfated CP, S-CP1-4 was obtained using chlorosulfonic acid-pyridine method. The chemical components and FT-IR spectrum confirmed that sulfated group was synthesized to the polysaccharide chains successfully. S-CP1-4 was found to inhibit nitric oxide production, phagocytic activity and the release of interleukin (IL)-6 and IL-1β in lipopolysaccharide-treated macrophage cells, RAW 264.7. S-CP1-4 significantly decreased the secretion of IL-6 and TNF-α and the thymus and spleen indexes, and increased the production of IL-10 in lipopolysaccharide-treated mice. S-CP1-4 could better protect the liver by inhibiting the activities of alanine aminotransferase and aspartate aminotransferase, and malondialdehyde level while increasing the superoxide dismutase activity and total anti-oxidative capacity. These results suggested that S-CP1-4 may be an effective anti-inflammatory agent, and sulfated modification may be a reliable method for the development of food supplements.
