Abstract
Two low-molecular-weight polysaccharides (DPSP50 and DPSP70) were obtained using hydrogen peroxide-vitamin C (H2O2-Vc) treatment at 50 °C and 70 °C, respectively. Both DPSP50 and DPSP70 comprised the same six monosaccharides in different ratios, and their molecular weights (Mws) were 640 kDa and 346 kDa, respectively. Functional properties analyses demonstrated that DPSP50 and DPSP70 each had an excellent water holding capacity, oil absorption capacity, and emulsion properties, as well as shear-thinning characteristics and viscoelastic properties. Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectroscopic assays confirmed the existence of α-, β-pyranose rings and the same six sugar residues in DPSP50 and DPSP70. The results of Congo red test, scanning electron microscopy (SEM), and X-ray diffraction (XRD) demonstrated that DPSP50 and DPSP70 did not contain triple-helix conformations, but were amorphous aggregates with flake-like shape and rough surface. Additionally, both DPSP50 and DPSP70 showed strong anti-complementary activities through the classical pathway and the alternative pathway. The results support the potential utility of these degraded polysaccharides from strawberry fruits in functional foods and medicines.

Abstract
At present, there are relatively few studies on the production of exopolysaccharide (EPS) by yeasts. Therefore, exploring the properties of EPS produced by yeast can not only enrich the source of EPS, but also play an important role in its future application in the food field. The aim of this study was to explore the biological activities of EPS (named SPZ) from Sporidiobolus pararoseus PFY-Z1, as well as the dynamic changes in physical and chemical properties that occur during simulated gastrointestinal digestion, and the effects of SPZ on microbial metabolites during fecal fermentation in vitro. The results revealed that SPZ had good water solubility index, water-holding capacity, emulsifying ability, coagulated skim milk, antioxidant properties, hypoglycemic activities, and bile acid-binding abilities. Furthermore, the content of reducing sugars increased from 1.20 ± 0.03 to 3.34 ± 0.11 mg/mL after gastrointestinal digestion, and had little effect on antioxidant activities. Moreover, SPZ could promote the production of short-chain fatty acids during fermentation for 48 h, in particular, propionic acid and n-butyric acid increased to 1.89 ± 0.08 and 0.82 ± 0.04 mmol/L, respectively. Besides this, SPZ could inhibit LPS production. In general, this study can help us to better understand the potential bioactivities, and the changes in bio-activities of compounds after digestion of SPZ.

Abstract
Two polysaccharides were separately extracted and purified from different types of medicinal slices of Massa Medicata Fermentata (Sheng Massa Medicata Fermentata and Chao Massa Medicata Fermentata). The physicochemical properties of these polysaccharides were studied, including the molecular weight, monosaccharide composition, and glycosidic linkage. Moreover, inhibition of trypsin, α-amylase, and α-glucosidase by the polysaccharides and their antioxidant activity were investigated. Compared with polysaccharides from Sheng Massa Medicata Fermentata, polysaccharides from Chao Massa Medicata Fermentata had a lower molecular weight, higher uronic acid content, and a lower proportion of side chains. Polysaccharides from Sheng Massa Medicata Fermentata displayed stronger trypsin, α-amylase, and α-glucosidase inhibition activity, whereas the antioxidant activity of the polysaccharides from Chao Massa Medicata Fermentata was higher. These results indicated that stir-frying changes the physicochemical properties of the polysaccharides significantly, leading to reduced enzyme inhibition activity and an increase in antioxidant activity. This research provides a guide for the selective application of Massa Medicata Fermentata.

Abstract
The structural characterization, the in vitro antioxidant activity, and the hypoglycemic activity of a polysaccharide (SGP-1-1) isolated from Siraitia grosvenorii (SG) were studied in this paper. SGP-1-1, whose molecular weight is 19.037 kDa, consisted of Gal:Man:Glc in the molar ratio of 1:2.56:4.90. According to the results of methylation analysis, GC–MS, and NMR, HSQC was interpreted as a glucomannan with a backbone composed of 4)-β-D-Glcp-(1→4)-, α-D-Glcp-(1→4)-, and 4)-Manp-(1 residues. α-1,6 linked an α-D-Galp branch, and α-1,6 linked an α-D-Glcp branch. The study indirectly showed that SGP-1-1 has good in vitro hypoglycemic and antioxidant activities and that these activities may be related to the fact that the SGP-1-1’s monosaccharide composition (a higher proportion of Gal and Man) is the glycosidic-bond type (α- and β-glycosidic bonds). SGP-1-1 could be used as a potential antioxidant and hypoglycemic candidate for functional and nutritional food applications.

Abstract
Diabetes mellitus is a prevalent metabolic and endocrine illness affecting people all over the world and is of serious health and financial concern. Antidiabetic medicine delivered through pharmacotherapy, including synthetic antidiabetic drugs, are known to have several negative effects. Fortunately, several natural polysaccharides have antidiabetic properties, and the use of these polysaccharides as adjuncts to conventional therapy is becoming more common, particularly in underdeveloped nations. Oxidative stress has a critical role in the development of diabetes mellitus (DM). The review of current literature presented here focusses, therefore, on the antioxidant properties of mushroom polysaccharides used in the management of diabetic complications, and discusses whether these antioxidant properties contribute to the deactivation of the oxidative stress-related signalling pathways, and to the amelioration of β-cell dysfunction and insulin resistance. In this study, we conducted a systematic review of the relevant information concerning the antioxidant and antidiabetic effects of mushrooms from electronic databases, such as PubMed, Scopus or Google Scholar, for the period 1994 to 2021. In total, 104 different polysaccharides from mushrooms have been found to have antidiabetic effects. Most of the literature on mushroom polysaccharides has demonstrated the beneficial effects of these polysaccharides on reactive oxygen and nitrogen species (RONS) levels. This review discuss the effects of these polysaccharides on hyperglycemia and other alternative antioxidant therapies for diabetic complications through their applications and limits, in order to gain a better understanding of how they can be used to treat DM. Preclinical and phytochemical investigations have found that most of the active polysaccharides extracted from mushrooms have antioxidant activity, reducing oxidative stress and preventing the development of DM. Further research is necessary to confirm whether mushroom polysaccharides can effectively alleviate hyperglycemia, and the mechanisms by which they do this, and to investigate whether these polysaccharides might be utilized as a complementary therapy for the prevention and management of DM in the future.

Abstract
Chaga mushroom is one of the promising beneficial mushrooms thriving in the colder parts of Northern hemisphere. Chaga polysaccharides (IOP) have been reported to enhance immune response and alleviate oxidative stress during development. However, the effects of IOP on the genotoxicity in model organisms are yet to be clarified. In this study, IOP was extracted using hot water extraction method, followed by GC analysis. Zebrafish embryos (12 h post fertilization, hpf) were exposed to transient UVB (12 J/m2/s, 305–310nm) for 10 s using a UV hybridisation chamber, followed by IOP treatment (2.5 mg/mL) at 24 hpf for up to 7 days post fertilization (dpf). The genotoxic effects were assessed using acridine orange staining, alkaline comet assay, and qRT-PCR for screening DNA repair genes. Significant reduction in DNA damage and amelioration of the deformed structures in the IOP-treated zebrafish exposed to UVB (p < 0.05) was observed at 5 dpf and thereafter. The relative mRNA expressions of XRCC-5, XRCC-6, RAD51, and GADD45 were significantly upregulated, whereas p53 and BAX were downregulated in IOP-treated UVB-exposed zebrafish compared to UVB-exposed zebrafish. ELISA analysis revealed significantly decreased expression of XRCC5 and RAD51 in UVB-exposed compared to IOP-treated UVB-exposed and control zebrafish (7 dpf). However, p53 and BAX levels were high in UVB-exposed zebrafish, indicating higher apoptosis. Pathway analysis demonstrated coordinated regulation of DNA repair genes; p53 playing a pivotal role in regulating the expression of BAX, thereby promoting apoptosis in UVB-exposed zebrafish. Overall, IOP treatment ameliorated the genotoxic effects in UVB-exposed zebrafish by enhanced expression of DNA repair genes, which assisted in normal development. The study delineated the efficacy of IOP in mitigating UV-induced DNA damage in zebrafish.

Abstract
The polysaccharide from Ribes nigrum L. (RCP) was modified by nitric acid-sodium selenite method. After purification by Sepharose-6B, high purity native (PRCP) and three selenized polysaccharides (PRSPs) with different selenium contents were obtained. Compared with PRCP, PRSPs possessed the lower molecular weight, better water-solubility, physical stability and rheological properties. FT-IR and NMR spectra confirmed PRSPs had the characteristic absorption peaks of polysaccharides and the glycosidic bond types were not changed after selenylation modification, whereas the selenyl groups existing in PRSPs were mainly introduced at the C-6 position of sugar residue →4)-β-d-Manp-(1→. Moreover, PRSPs displayed obviously smoother and smaller flaky structure than PRCP, and their inhibitory effects on α-amylase and α-glucosidase also were greater than PRCP. PRSPs exhibited a reversible inhibition on two enzymes in competitive manner and quenched their fluorescence through the static quenching mechanism. The polysaccharide-enzyme complex was spontaneously formed mainly driven by the hydrophobic interaction and hydrogen bonding.

Abstract
Ribes meyeri leaves are used as traditional Kazakh medicine in China. However, no study on the characterization of the phenolic compounds in R. meyeri leaves has been reported, resulting in the lack of quality control measures and poor standardization. This study was conducted to identify the phenolic compounds in R. meyeri leaves and evaluate their antioxidant and antidiabetic activities. A total of 77 phenolics were tentatively identified by liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry. Ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry was applied to simultaneously quantify 12 phenolics in R. meyeri leaves. Rutin, epigallocatechin, isoquercitrin, epicatechin, protocatechuic acid, and kaempferol-3-O-rutinoside were abundant in the R. meyeri leaves. The methanol extract and four different extracts enhanced the glucose uptake in 3T3-L1 adipocytes. The ethyl acetate extracts showed a total phenolic content of 966.89 ± 3.59 mg gallic acid equivalents/g, a total flavonoid content of 263.58 ± 17.09 mg catechin equivalents/g, and good protein-tyrosine phosphatase-1B inhibitory activities (IC50 : 0.60 ± 0.03 μg/mL). To our knowledge, this work is the first to identify and quantify the major phenolics in R. meyeri leaves.

Abstract
Abelmoschus esculentus L (okra) is widely used as a healthy vegetable and favourable source of dietary medicine. Okra flowers which are by-products of okra, are rich in polysaccharide, polyphenols and trace elements etc., however, except a few for health tea, most of them were discarded as the waste of resources. In this study, a polysaccharide named AEFP22 was extracted, purified and identified from okra flowers, and its physicochemical property and antioxidant activity were also elucidated. AEFP22, with a molecular weight of 2.741 × 105 Da, was composed of Rha, GalA and Gal in the ratio of 1: 1.02: 0.86. The methylation and nuclear magnetic resonance (NMR) analysis indicated AEFP22 was composed of [2)-α-D-Rhap-(1 → 4)-α-D-GalpA-(1 → 2,4)-α-D-Rhap-(1 → 4)-α-D-GalpA-(1] with branch of terminal T-α-D-Galp pointed at C4 of 1,2,4-α-D-Rhap. The Conge-red test, Atomic force microscope (AFM) and Scanning electron microscope (SEM) further revealed the triple-helical conformation, irregular sheet structure with molecule aggregations of AEFP22. The physicochemical property analysis indicated AEFP22 possessed stable thermal property and exhibited shear-thinning and normal Newtonian fluid in different concentrations, -7.04 mV zeta potential and polymerization phenomenon existed in AEFP22 solution. AEFP22 exhibited good 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging ability. These results indicated potential utilization of AEFP22 in nutritional food and material application.

J Food Biochem 2019; 44:e13126. [PMID: 31877235 DOI: 10.1111/jfbc.13126] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Revised: 10/17/2019] [Accepted: 11/28/2019] [Indexed: 12/11/2022]
Abstract
Garlic protein (GP) was enzymatically hydrolyzed using pepsin and trypsin followed by the evaluation of antioxidant and angiotensin-converting enzyme (ACE) inhibitory activities of GP and its hydrolysates. The antihypertensive effects of GP and its hydrolysates were determined in vivo. The results showed that GP and its hydrolysates namely GPH-P (pepsin) and GPH-T (trypsin) possessed appreciable antioxidant and ACE inhibitory activities. The ACE inhibitory activity of GP, GPH-T, and GPH-P was in consistent with their antioxidant activities. GP and its hydrolysates offered significant protective effects against H2 O2 -induced oxidative damage (p < .05). In addition, the administration of GP, GPH-T, and GPH-P reduced the blood pressure in hypertensive rats. The mechanism might be to reduce blood pressure by inhibiting the activity of ACE, reducing the formation of ACEII, and protecting the activity of bradykinin. This study suggested that GP might be utilized as a promising functional food as antioxidant and antihypertensive agents. PRACTICAL APPLICATIONS: Garlic (Allium sativum L.) is one of the oldest cultivated plants that belongs to the Liliaceae family and it has been used in cooking and medicinal applications. Large quantities of garlic residuals were produced with the development of the garlic essential oil industry. These residuals are highly rich in proteins and they can be used for the preparation of protein hydrolysates. Generally, hydrolysates are considered as a promising food supplement due to the enrichment of amino acids present in it. In this study, garlic proteins (GPs) and its hydrolysates retain effective antioxidant effects. They were found to reduce the blood pressure and prevent oxidative stress induced by H2 O2 . The information from this study could be used to develop a new nutritional supplement from GP and its hydrolysates to treat hypertension as well as prevent oxidative damage.
