Physiochemical changes, metabolite discrepancies of brown seaweed-derived sulphated polysaccharides in the upper gastrointestinal tract and their effects on bioactive expression. Int J Biol Macromol 2024; 272:132845. [PMID: 38830495 DOI: 10.1016/j.ijbiomac.2024.132845] [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: 02/12/2024] [Revised: 05/09/2024] [Accepted: 05/31/2024] [Indexed: 06/05/2024]
Abstract
Brown seaweed-derived polysaccharides, notably fucoidan and laminarin, are known for their extensive array of bioactivities and physicochemical properties. However, the effects of upper digestive tract modification on the bioactive performance of fucoidan and laminarin fractions (FLFs) sourced from Australian native species are largely unknown. Here, the digestibility and bioaccessibility of FLFs were evaluated by tracking the dynamic changes in reducing sugar content (CR), profiling the free monosaccharide composition using LC-MS, and comparing high-performance gel permeation chromatography profile variation via LC-SEC-RI. The effects of digestive progression on bioactive performance were assessed by comparing the antioxidant and antidiabetic potential of FLFs and FLF digesta. We observed that molecular weight (Mw) decreased during gastric digestion indicating that FLF aggregates were disrupted in the stomach. During intestinal digestion, Mw gradually decreased and CR increased indicating cleavage of glycosidic bonds releasing free sugars. Although the antioxidant and antidiabetic capacities were not eliminated by the digestion progression, the bioactive performance of FLFs under a digestive environment was reduced contrasting with the same concentration level of the undigested FLFs. These data provide comprehensive information on the digestibility and bioaccessibility of FLFs, and shed light on the effects of digestive progression on bioactive expression.

Abstract
This study aims to extract an active heteropolysaccharide Chia seed polysaccharide (CSP-A) and further purified by DEAE Sepharose Fast Flow and Sepharose CL-6B chromatographic column, characterize its structure, and evaluate its antioxidant and immunomodulatory activities. Structural analysis revealed that CSP-A was composed of d-mannose, d-glucuronic acid and d-xylose in a molar ratio of 1:3:4 with molecular weight of 1.688 × 105 Da, owning 4 sugar residues of β-d-Manp-(1→, →4)-α-d-GlcpA-(1→, →2,4)-β-d-Xylp-(1→, and → 4)-β-d-Manp-(1 →. Congo red assay and microscopic characteristics showed that CSP-A in its solution may possess a helical conformation. In vitro experiments showed that CSP-A had moderate DPPH· and OH· scavenging activities. CSP-A also enhanced the phagocytosis ability of RAW 264.7 cells and prompted the release of NO, TNF-α, IL-6 and IL-1β from RAW 264.7 cells, which indicated CSP-A had immune regulation effect. This experiment provides scientific basis for further utilization and development of chia seeds, a kind of functional food.

Effects of Tremella fuciformis Mushroom Polysaccharides on Structure, Pasting, and Thermal Properties of Chinese Chestnuts ( Castanea henryi) Starch Granules under Different Freeze-Thaw Cycles. Foods 2023; 12:4118. [PMID: 38002176 PMCID: PMC10670311 DOI: 10.3390/foods12224118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 11/07/2023] [Accepted: 11/08/2023] [Indexed: 11/26/2023] Open
Abstract
The purpose of this study was to investigate the effect of Tremella fuciformis polysaccharides on the physicochemical properties of freeze-thawed cone chestnut starch. Various aspects, including water content, crystallinity, particle size, gelatinization, retrogradation, thermal properties, rheological properties, and texture, were examined. The results revealed that moderate freezing and thawing processes increased the retrogradation of starch; particle size, viscosity, shear type, hinning degree, and hardness decreased. After adding Tremella fuciformis polysaccharide, the particle size, relative crystallinity, and gelatinization temperature decreased, which showed solid characteristics. Consequently, the inclusion of Tremella fuciformis polysaccharide effectively countered dehydration caused by freezing and thawing, reduced viscosity, and prevented the retrogradation of frozen-thawed chestnut starch. Moreover, Tremella fuciformis polysaccharide played a significant role in enhancing the stability of the frozen-thawed chestnut starch. These findings highlight the potential benefits of incorporating Tremella fuciformis polysaccharides in starch-based products subjected to freeze-thaw cycles.

Abstract
Polysaccharides are promising biomolecules with lowtoxicity and diverse bioactivities in food processing and clinical drug development. However, an essential prerequisite for their applications is the fine structure characterization. Due to the complexity of polysaccharide structure, partial degradation is a powerful tool for fine structure analysis, which can effectively provide valid information on the structure of backbone and branching glycosidic fragments of complex polysaccharides. This review aims to conclude current methods of partial degradation employed for polysaccharide structural characterization, discuss the molecular mechanisms, and describe the molecular structure and solution properties of degraded polysaccharides. In addition, the effects of polysaccharide degradation on the conformational relationships between the molecular structure and bioactivities, such as antioxidant, antitumor, and immunomodulatory activities, are also discussed. Finally, we summarize the prospects and current challenges for the partial degradation of polysaccharides. This review will be of great value for the scientific elucidation of polysaccharide fine structures and potential applications.

Structural characterization of exopolysaccharide from Leuconostoc mesenteroides P35 and its binding interaction with bovine serum albumin using surface plasmon resonance biosensor. Int J Biol Macromol 2023; 246:125599. [PMID: 37385309 DOI: 10.1016/j.ijbiomac.2023.125599] [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: 01/24/2023] [Revised: 06/14/2023] [Accepted: 06/26/2023] [Indexed: 07/01/2023]
Abstract
This paper describes the structural elucidation of Leuconostoc mesenteroides P35 exopolysaccharide (EPS-LM). Ln. mesenteroides P35 strain was isolated from a French goat cheese for its capacity to produce EPS increasing the viscosity of a whey-based fermentation medium. The chemical structure of EPS-LM analysis was elucidated by determination of optical rotation degree, macromolecular characterization, sugar units and methylation analyses, FT-IR, 1D NMR spectroscopy (1H and 13C NMR), 2D NMR spectroscopy (1H1H COSY, HSQC and HMBC). EPS-LM was a high molecular weight (ranging from 6.7 × 106 Da to 9.9 × 106 Da) dextran that is composed of only d-glucose units containing α (1 → 6) linkages and paltry α (1 → 3) branches. Since polysaccharide-protein interactions can be exploited to control and design food matrices, EPS-LM interactions with bovine serum albumin (the main constituent of bovine plasma) were investigated by surface plasmon resonance (SPR). Kinetic properties of EPS-LM binding with immobilized BSA via showed an increase of EPS-LM affinity (equilibrium constant (Kd)) for BSA from (2.50 ± 0.01) × 10-5 M-1 at 298 K to (9.21 ± 0.05) × 10-6 M-1 at to 310 K. The thermodynamic parameters revealed that van der Waals and hydrogen binding forces play a major role in the interaction of EPS-LM with BSA. However, EPS-LM-BSA interaction was non-spontaneous, entropy driven and an EPS-LM - BSA binding process was endothermic (ΔG > 0). The structural findings suggested that Ln. mesenteroides P35 α-D-glucan might find widespread technological applications in the biopolymer, medical and food industries.

Development of antimicrobial gelatin-ulvan-beeswax composite films: Optimization of formulation using mixture design methodology. Int J Biol Macromol 2023; 231:123384.

Abstract
A new generation of antimicrobial film was developed by incorporation of ulvan extracted from Ulva intestinalis into gelatin from common carp scale and its water sensitivity was reduced with addition of beeswax. Optimum composition of gelatin (0-100%w/w), ulvan (0-100%w/w) and beeswax (0-10%w/w) for achieving composite films with minimum water solubility (S) and water vapor permeability (WVP) and maximum tensile strength (TS), elongation at break point (EAB) and antibacterial effect on E. coli (EC) were investigated using mixture design methodology. Both pure gelatin and ulvan films and their composites had relatively good mechanical and optical properties. Addition of ulvan to gelatin produced composite films with good antibacterial properties but water resistance of all the films was weak. Addition of beeswax up to ∼5 % improved the water resistance and mechanical properties of the films without jeopardizing their antibacterial properties. The final optimum formulation with a desirability of 0.709 was achieved as 52.18 % of gelatin, 40.83 % of ulvan and 6.97 % of beeswax resulting in a minimum possible S (40 %) and WVP (1.86 10-10 g/ms Pa) and maximum possible TS (6.23 MPa) and EAB (89 %) with good EC (7.66 mm). Finally, good mechanical, thermal and microstructural properties of the optimum composite film was confirmed. Altogether, a combination of ulvan and beeswax can be a promising solution for development of gelatin films with both antimicrobial properties and lower water sensitivity.

Abstract
A predominant polysaccharide isolated from Ischnoderma resinosum underwent evaluation for its capacity to scavenge free radicals and its potential antioxidant properties at a cellular-oriented level. This proved that Ischnoderma resinosum polysaccharide (IRP) remarkably curtailed AAPH-induced erythrocyte hemolysis through the inhibition of the generation of ROS (p < 0.05). Rather, it caused the restoration of intracellular antioxidant enzyme (SOD, GSH-Px, and CAT) activities at an acceptable pace and the silencing of intracellular MDA formation, as well as the rescaling of LDH leakage. Furthermore, a model of oxidative stress in HepG2 cells was established by adopting 400 μM of hydrogen peroxide, which suggested that IRP manifests promising antioxidant activity. Notably, after the intervention of IRP in the H2O2-induced HepG2 cells, there was a statistical elevation in cell survivability (p < 0.05). IRP diminished the morphological alterations in the nucleus and decreased the secretion of ROS (p < 0.05), with a dose-dependent abrogation of apoptosis (p < 0.05). Consequently, IRP, which was isolated and purified, was able to scavenge free radicals and possessed favorable antioxidant activity that could dampen the occurrence of oxidative stimulation and effectively alleviate the AAPH-induced erythrocyte hemolysis and H2O2-induced oxidative damage in HepG2 cells. This provides a basis and theoretical reference for the development and utilization of IRP as a natural antioxidant, with emphasis on the exploitation of environmentally friendly and cost-effective antioxidants.

Abstract
In this paper, a pectin polysaccharide AP2-c with molecular weight 6.69 × 105 Da was obtained from the lignified okra. The monosaccharide composition analysis indicated that AP2-c consisted of galactose, rhamnose and galacturonic acid in a molar ratio of 2.3: 1.5: 1.5. The structural characterization indicated that the main chain of AP2-c was composed of →2)-α-L-Rhap-(1→ and →4)-α-D-GalAp-(1→. →2)-α-L-Rhap-(1→ was branched at position O-4 and the branched chain consisted of →3,6)-β-D-Galp-(1→, →6)-β-D-Galp-(1→, α-L-Rhap-(1→ and β-D-Galp-(1→. AP2-c could inhibit the mRNA expression levels of TNF-α, IL-1β and iNOS in LPS-induced macrophages with a dose-dependent manner. Furthermore, AP2-c inhibited the phosphorylation of IκB and p65 via NF-κB pathway. The results indicated that AP2-c had obvious anti-inflammatory activity. PRACTICAL APPLICATIONS: When okra seeds were harvested, lignified okra was always abandoned as waste and had not been fully used for exploitation. Nevertheless, it accounted for more than half of the total plant's weight and was abundant in cell wall polysaccharides, which were the main components of okra to perform a variety of biological functions. In the research, the purified pectin polysaccharide AP2-c was obtained from lignified okra and its physicochemical properties, structural features and anti-inflammatory activity were systematically researched. It was detected that AP2-c exhibited anti-inflammatory activity by blocking NF-κB pathway and thus lowering the expression of related inflammatory factors. The results have significant implications for the value-added application of okra and its processing side products can obviously help to promote the anti-inflammatory application of AP2-c and avoid wasting resources.

Abstract
Along with the increasing attempts to explore the wound healing effective substances of Periplaneta americana (L.) (PA), a medicinal insect in traditional Chinese medicine, researchers' attention turned to the endogenetic macromolecules, such as polysaccharides and peptides. Herein, we innovatively isolated two glycoproteins from PA, named PAGP-1 and PAGP-2, which were obtained by Cellulose DE-52 chromatography and purified by Sephadex G-100 gel in succession. The structural characterization of the two PAGPs were performed, including molecular weight, amino acid and monosaccharide composition, morphology analysis, FT-IR and 1H NMR analysis, CD spectroscopy, and glycosides linkage. As a result, two PAGPs belonged to O-glycopeptide bonds linked glycoproteins. The content of carbohydrate and protein of PAGP-1 was approximately 25.23% and 65.92% respectively, which of PAGP-2 was approximately 25.71% and 71.23%. Based on the remarkable anti-inflammatory effects of PAGPs on LPS-induced RAW264.7 cells, the topical administration of PAGP-1 and PAGP-2 could significantly accelerate full-thickness wound healing in diabetic mice, involving to alleviate the inflammation, increase the ratio of type I and type III collagen fibers, and promote the polarization of macrophages M1 to M2. In short, this study provides clear evidence that the glycoproteins would be the potential wound healing bioactive substances in PA.

[PMID: 35627036 PMCID: PMC9140784 DOI: 10.3390/foods11101464] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 05/12/2022] [Accepted: 05/16/2022] [Indexed: 11/16/2022] Open
Abstract
Auricularia cornea var. Li. polysaccharide (ACP) has many important biological activities and has potential application value in food engineering, pharmaceutical science, and health care. The results were as follows: the extraction rate of ACP was 28.18% ± 1.41% and the purity of ACP was 86.92% ± 2.80%. ACP contains mannitol 32.41%, glucuronic acid 6.96%, rhamnose 0.32%, glucose 42.35%, galactose 0.77%, xylose 16.83%, and fucose 0.36%, without galacturonic acid and arabinose. In addition, the results of an animal test of diabetes mellitus II (DM II) with ACP showed that the total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and fasting blood glucose and water in the serum of mice with ACP were significantly lower than those in the model group; the serum SOD, hepatic glycogen, and insulin of mice added with ACP were significantly higher than those in the model group. More importantly, ACP had no significant adverse effects on organ index and liver and kidney tissue morphology in mice. These results suggest that ACP can be used as a potential functional food component for the prevention or treatment of diabetes.

Abstract
Gum ammoniacum is a polymer obtained from Dorema ammoniacum and its medicinal use was already known to the ancient times. In this study, a new D. ammoniacum carbohydrate (DAC-1) with a molecular weight of 27.1 kDa was extracted by hot water and then purified on DEAE-52-cellulose and Sephadex G-100 columns. The structural features of DAC-1 were investigated by partial acid hydrolysis, fourier-transform infrared spectroscopy (FT-IR), methylation, gas chromatography-mass spectrometry (GC-MS), gas chromatography-flame ionization detection (GC-FID), and 1D and 2D nuclear magnetic resonance spectroscopy (1D & 2D NMR). The results indicated that DAC-1 was an arabinogalactan including galactose, arabinose, rhamnose, glucuronic acid and 4-O-methyl-β-d-glucopyranosyl uronic acid (meGlcpA) with a relative percentage of 44.63%, 23.30%, 13.46%. 12.47%, and 6.14%. The structure units of DAC-1 were elucidated as 3,1)-β-D-Galp-(6 → 1)-β-D-Galp-(3,6 → containing four branch chains of →1,6)-β-D-Galp-(3 → 1)-α-L-Araf-(5 → 1)-β-D-GlcpA-(4 → 1)-α-L-Rhap-T (two times), →1,6)-β-D-Galp-(3→1)-β-D-Galp-(3 → 1)-β-D-Galp-(3 → 1)-β-D-Galp-(3 → 1)-α-L-Araf-T and →1,6)-β-D-Galp-(3 → 1)-α-L-Araf-(5 → 1)-β-D-meGlcpA-T. X-ray diffraction (XRD) pattern indicated a semi-crystalline structure. Thermal behavior of the polysaccharide was evaluated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) and revealed temperatures higher than 200 °C as dominant region of weight loss. DAC-1 showed acceptable antioxidant activity when analyzed by DPPH, ABTS, FRAP, and OH radical removal methods.

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
A sensitive and efficient fluorescence labeling method was developed and validated for the microanalysis and detection of polysaccharides. Fluorescein isothiocyanate (FITC) was successfully labeled on mulberry fruit polysaccharides (MFP) through a reductive amination reaction with the assistant of tyramine. The fluorescent labeled polysaccharides (FMFP) was identified by fluorescence, UV-visible, flourier transform infrared (FT-IR) and 1H NMR spectrum. Results demonstrated that the labeling efficiency of FMFP was 0.32%, and the FMFP was stable in simulated digestion fluid without cytotoxicity. The pharmacokinetics and biodistribution after administration were analyzed in rats, which indicated that the FMFP obtained could be absorbed in a short time (tmax 0.50 h) but eliminated slowly (t1/2 8.77 ± 1.38 h). At 24 h after administration, the polysaccharide could be tested mainly in intestine, stomach, liver and kidney. The FITC labeling method lays a foundation for investigating the absorption and metabolism of MFP, and provides references for the microanalysis research of bioactive polysaccharides.

Abstract
In this study, a novel polysaccharide fraction from Ocimum album seed was extracted and then purified by Cellulose DEAE-52 and Sephadex G-200 anion exchange chromatography. The structural, physicochemical and antioxidant properties of the main polysaccharide fraction (OAP-1A) were evaluated. The purified polysaccharide contained 94.3% carbohydrate, 3.56% moisture and 2.14% ash and result of gel permeation chromatography (GPC) showed average molecular weight of 593 kDa. The results of high-performance liquid chromatography (HPLC) showed that OAP-1A was a neutral hetero-polysaccharide composed of mannose (35.7%), glucose (33.32%), galactose (19.6%) and rhamnose (11.38%). In addition, GC-MS data, nuclear magnetic resonance (NMR) spectrum and Fourier transform infrared (FT-IR) analysis revealed that the backbone of OAP-1A consists of →3)-β-D-Manp-(1→, →3,4)-β-D-Manp-(1→, →3,6)-β-D-Manp-(1→, →3)-α-D-Glcp-(1→, →6)-β-D-Galp-(1→, →4)-α-L-Rhap-(1→ and α-D-Glcp-(1→. X-ray diffraction (XRD) analysis showed semi-crystalline structure in OAP-1A. Differential scanning colorimeter (DSC) and thermo-gravimetry analysis (TGA) indicated that OAP-1A had relatively high thermal stability. Moreover, OAP-1A showed strong scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals.

Abstract
In this research, a novel polysaccharide (PCP) was extracted from Pleurotus citrinopileatus and purified by Sephadex G-150 gel column, and its antitumor activity was investigated using the model H22 tumor-bearing mice. PCP was found to be composed of arabinose, galactose, glucose, xylose, mannose and glucuronic acid in a proportion of 0.66: 14.59: 10.77: 1: 0.69: 0.23 with average molecular weight of 7.30 × 105 Da. Further analysis suggested that PCP was a pyranose with α-type and β-type glycosidic residues. The antitumor assays in vivo indicated that PCP could effectively suppress H22 solid tumor growth, protect immune organs and improve inflammation and anemia. Besides, Annexin V-FITC/PI double staining and JC-1 staining demonstrated that PCP could induce apoptosis of H22 hepatoma cells. The PI staining assay revealed that PCP induced H22 hepatoma cells apoptosis by arresting cell cycle in S phase. These results suggest that the polysaccharide from Pleurotus citrinopileatus possesses potential value in the treatment of liver cancer.

Abstract
In this study, two polysaccharide fractions were isolated from wheat bran by sequential extraction with water and alkaline solution, DEAE Cellulose-52 chromatography and Sephacryl S-400 gel permeation chromatography, they were named as WXA-1 and AXA-1, respectively. Structural analyses indicated that both polysaccharide fractions were heteropolysaccharides, their average molecular weights were 193 kDa and 107 kDa, respectively. The backbone of WXA-1 was → 4)-β-d-Xylp-(1→, which was substituted at O-3 positions by arabinose, glucose and galactose residues, while the backbone of AXA-1 was → 4)-β-d-Xylp-(1→, which was mainly substituted at O-3 positions by arabinose. AXA-1 exerted a stronger inhibitory effect on the activities of α-amylase and α-glucosidase compared with WXA-1. Moreover, AXA-1 exhibited a competitive inhibition of α-amylase and a mixed-type noncompetitive inhibition of α-glucosidase. These results suggest that AXA-1 can be used as α-amylase and α-glucosidase inhibitors.

Abstract
It is an important aspect of current cancer research to search for effective and low-toxicity anticancer drugs and adjuvants. Polysaccharides, as immunomodulators, can improve the immune function of the body, kill tumor cells directly and prevent tumor development by increasing the resistance of the body to carcinogenic factors. The aim of the present study was to identify natural polysaccharide compounds with novel structure and antitumor activity via the separation and analysis of polysaccharide components from Ramaria flaccida (Fr.) Quél. (RF-1). In the present study, high-performance gel permeation chromatography, gas chromatography-mass spectrometry and nuclear magnetic resonance were used to identify the structure of polysaccharides from RF-1. Subsequently, the antitumor activity and mechanism of RF-1 were studied by establishing an in vivo S180 tumor model, and by using Illumina sequencing technology and enzyme-linked immunosorbent assay (ELISA). The present results revealed that the average molecular weight of RF-1 was 17,093 Da and that RF-1 was composed of the monosaccharides glucose and galactose, with a 2:1 ratio. The main chain of RF-1 consisted of (1→6, 2)-α-D-galactopyranose and (1→6, 4)- α-D-glucopyranose. One of the branched chains was linked to 4-O of the main glucose chain by (1→6)-α-D-glucopyranose and next linked by one (→4)-β-D-glucopyranose. The other two branched chains were both linked to 2-O of the main glucose chain by one (→4)-β-D-glucopyranose. In addition, RF-1 inhibited the growth of S180 tumors in vivo. When the concentration of RF-1 was 20 mg/kg, the inhibition rate of S180 tumors in mice was 48.4%. Compared with the blank control group, 1,971 differentially expressed genes were identified, of which 818 were upregulated and 1,153 were downregulated in the RF-1 group. A Gene Ontology enrichment analysis generated 47,091 assignments to biological processes, 5,250 assignments to cellular components, and 6,466 assignments to molecular functions. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that the Wnt and MAPK signaling pathways were significantly enriched. The number of differentially annotated genes in these two pathways was 19 and 33, respectively. Additionally, ELISA results revealed that the protein levels of interleukin (IL)-1β, IL-6, vascular endothelial growth factor (VEGF) and VEGF receptor in the RF-1 group were significantly downregulated compared with the S180 blank control group (P<0.01).

Abstract
The aim of this work was to extract, isolate, and purify polysaccharides from the heads of Hypomesus olidus and to evaluate their anticoagulant activities and anticoagulant mechanisms. Response surface methodology was used to optimize the extraction conditions for ultrasonic-assisted extraction of polysaccharides from the heads of Hypomesus olidus. The optimal extraction conditions consisted of ultrasonic power of 275 W, ultrasonic time of 50 min, and solid-liquid ratio of 5 ml/g, giving the yield of crude polysaccharides (GYT) of 7.73 ± 0.042%. Three polysaccharide fractions, GYT-1, GYT-2, and GYT-3 were purified from GYT by using DEAE-cellulose-52 column and Sephadex G-100 column for anticoagulant activities. The results showed that two doses (2 and 4 mg/ml) of GYT-1 and GYT-3 could significantly prolong (p < .01) in partial thromboplastin time (APTT) (2.19 and 2.37 times, 2.22 and 2.44 times, respectively) and thrombin time (TT) (2.39 and 2.46 times, 2.44 and 2.80 times, respectively) compared with normal control. In particular, GYT-3 had stronger anticoagulant activity than GYT-1, and it was composed of arabinose, fructose, glucose, and lactose with molar ratios of 0.595:1: 2.026:0.273. However, GYT-2 had no anticoagulant activity (p > .05). In addition, anticoagulation mechanism of polysaccharides from the heads of Hypomesus olidus (GYT-3) was evaluated. The results showed that the anticoagulant activity of GYT-3 was based on their binding with antithrombin AT-III. And the inhibitory effects of GYT-3 on factor IIa and Xa were related to the concentration of AT-III in plasma. This study may provide a new and promising anticoagulant drug.

Abstract
Humulus lupulus is a perennial climbing plant of the subfamily Cannabioideae native to the Northern Hemisphere. The primary use of H. lupulus is in the brewing industry, where it is an essential ingredient for imparting a unique flavor (bitterness and aroma) to beer. The female flowers of H. lupulus are also used in traditional Chinese medicine, but the biologically active ingredients underlying its benefits remain unclear. China is the largest producer and consumer of H. lupulus in Asia. Using the waste from the beer-brewing process of H. lupulus as raw materials, the biologically active polysaccharides can be screened. This is useful for the full utilization of H. lupulus, potentially leading to disease prevention and treatment. In this study, we isolated a homogeneous polysaccharide (HLP50-1) with a molecular weight of 49.13 kDa from female flowers of H. lupulus via a DEAE-Cellulose 52 anion exchange column and a Sephadex G-75 gel filtration column. Methylation, GC-MS, and NMR analyses revealed that the HLP50-1 comprised →4)-α-d-Glcp-(1→, →6)-α-d-Manp-(1→, →3)-α-l-Rhap-(1→, β-d-Glcp-(1→, α-l-Araf-(1→, →4,6)-2-OAc-β-d-Galp-(1→, β-d-Galp-(1→, →3,6)-β-d-Glcp-(1→, →2,3,4)-α-d-Xylp-(1→, →6)-α-d-Glcp-(1→, →3)-α-d-Galp-(1→, →4)-α-d-Galp-(1→. Advanced structural analysis showed that the HLP50-1 contained irregular fragments of different sizes and shapes with a smooth surface. The aggregates appeared be composed of accumulated crystals. Furthermore, the osteogenic activities of the HLP50-1 were evaluated via MC3T3-E1 cells in vitro. The results showed that 0.13 μM HLP50-1 led to outstanding proliferation, differentiation, and mineralization of the MC3T3-E1 cells. Therefore, HLP50-1 has osteogenic effects, and it may be a candidate for the treatment of osteoporosis. It has broad application prospects in functional foods, health-care products, and pharmaceuticals.

Abstract
Auricularia cornea var. Li. is an edible fungi and polysaccharides in Auricularia cornea var. Li. may have bioactive activities. Polysaccharides from Auricularia cornea var. Li. (ACP) was extracted using ultrasound-assisted extraction (UAE) method and compared with hot water extraction (HWE) for extraction yield, extraction rate, purity of polysaccharides, microstructure of residues after extraction, preliminary structure and rheological properties of polysaccharides. Optimum conditions for UAE (particle size of 150⁻200 mesh, water to raw material ratio of 70:1, extraction temperature at 70 °C for 40 min, ultrasonic amplitude of 40%) and HWE (particle size of 150⁻200 mesh, water to raw material ratio of 60:1, extraction temperature at 90 °C for 3.0 h) were obtained via single-factor experiment. Under optimum conditions, extraction yield of polysaccharides by UAE was 30.99 ± 1.93% which showed no significant difference with that by HWE (30.35 ± 1.67%) (P > 0.05). Extraction rate (29.29 ± 1.41%) and purity (88.62 ± 2.80%) of polysaccharides by UAE were higher than those by HWE (extraction rate of 24.95 ± 2.78% and purity of 75.33 ± 6.15%) (P < 0.05). Scanning Electron Microscopy (SEM) images of residues by UAE showed more broken cells than those by HWE. Fourier Transform Infrared (FTIR) spectra showed that the dialyzed ACP extracted by HWE and UAE (DACP-HWE and DACP-UAE) had similar characteristic absorption peaks of polysaccharides. Both DACP-HWE and DACP-UAE solutions showed typical shear thinning and temperature-independent behaviors (25⁻90 °C) and UAE resulted in polysaccharides with remarkably lower viscosity in comparison with HWE. DACP-UAE solutions exhibited more liquid-like state while DACP-HWE solutions solid-like system. Data indicated that ultrasound treatment may be a useful means for extraction of polysaccharides from Auricularia cornea var. Li.

Abstract
Enzyme assisted extraction was used to extract the polysaccharides from pumpkin seeds (PSP) and the extraction parameters were optimized by response surface methodology (RSM). Under the optimum experimental parameters: Extraction temperature of 60 °C, extraction time of 43 min, enzyme concentration of 2.5%, and pH of 6.0, the yield of PSP was 3.22 ± 0.04%, which was in close agreement with the predicted value (3.24%). After further purification on anion exchange column and gelfiltration column, a novel purified polysaccharide (PSPE) with molecular weight of 16,700 g/mol was obtained. PSPE was mainly composed of mannose, galactose and glucose in the molar ratio of 1.00:3.84:1.62. NMR spectra analysis showed that the major backbone of PSPE consisted of →4)-α-d-Glcp-(1→, →4)-β-d-Manp-(1→, →3,6)-β-d-Glap-(1→, and β-d-galactose.
