Fu, Yuan published the artcilePolysaccharides from loquat (Eriobotrya japonica) leaves: Impacts of extraction methods on their physicochemical characteristics and biological activities, Application In Synthesis of 59-23-4, the main research area is Eriobotrya polysaccharide extraction method physicochem characteristics biol activity; Bioactivity; Chemical structure; Extraction method; Loquat; Polysaccharide.

Impacts of hot water extraction (HWE), pressurized water extraction (PWE), high-speed shearing homogenization extraction, microwave assisted extraction (MAE), ultrasound assisted extraction (UAE), ultrasound assisted enzymic extraction, and ultrasound-microwave assisted extraction (UMAE) on physicochem. characteristics and bioactivities of polysaccharides from loquat (Eriobotrya japonica) leaves (LLPs) were investigated. Results showed that the degrees of esterification, contents of phenolics and uronic acids, constituent monosaccharides, apparent viscosities, and mol. weights of LLPs varied by different extraction methods. Bioactivities of LLPs were also significantly affected by different extraction methods. The high mol. weight and high degree of esterification of LLP-W and LLP-P extracted by HWE and PWE, resp., might contribute to their strong binding capacities. The strong antioxidant activities and inhibitory effects on α-amylase and α-glucosidase were found in LLP-M and LLP-U extracted by MAE and UAE, resp., which might be attributed to their contents of uronic acids, contents of total phenolics, and mol. weights The low mol. weights and viscosities of LLP-U and LLP-UM extracted by UMAE might contribute to their strong prebiotic effects. These findings could provide scientific foundations for selecting appropriate extraction methods to obtain LLPs with desired bioactivities for applications in the pharmaceutical and functional food industries.

Pegler residues, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Lentinula soluble dietary fiber fraction structure thermal rheol property.

Four soluble dietary fiber subfractions were obtained via stepwise ethanol precipitation from Lentinula edodes byproducts (LESDF). The mol. weight distributions of these four LESDF subfractions were 6.43 × 107 Da, 6.25 × 106 Da, 1.58 × 105 Da and 2.50 × 104 Da, resp., and they exhibited different surface morphol. properties, particle size distribution, ζ-potential and apparent viscosity. Different structural features of LESDF subfractions were analyzed through monosaccharide composition, FT-IR, periodate oxidation and smith degradations These characteristics affected their thermal (TGA-DSC) properties and the rheol. properties of LESDF-containing doughs. Results indicated that the higher the mol. weight of LESDF products, the greater the loss of dietary fiber weight by degradation Meanwhile, LESDF-3 exhibited the most rheol. benefits and the possible repeating unit were investigated by 1D/2D NMR. It was found that addition of LESDF with medium mol. weight and high branching degree played an important role in improving dough elasticity.

Jia, Mengyun published the artcileStructural characteristics and functional properties of soluble dietary fiber from defatted rice bran obtained through Trichoderma viride fermentation, Application of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Trichoderma fermentation soluble dietary fiber defatted rice bran.

Trichoderma viride was utilized to ferment the defatted rice bran (DRB), and soluble dietary fiber was prepared before and after fermentation, named as B-SDF and F-SDF, resp. Optimum fermentation conditions for yield of F-SDF were determined using response surface methodol. (RSM). The yield of F-SDF was significantly increased from 10.5 (weight/weight, %) to 33.4 (weight/weight, %) under the optimal conditions (inoculum size = 10%, pH = 5.8 and time = 41 h). Fourier transform IR spectroscopy (FTIR) demonstrated that both B-SDF and F-SDF had typical characteristics of the IR spectrum of polysaccharides, and X-ray diffraction (XRD) revealed they were mainly substances of amorphous structure. In addition, F-SDF showed looser structure by SEM (SEM) anal., increased mol. weight by high-performance gel permeation chromatog. (HPGPC) anal., and more complex monosaccharide composition by high-performance anion exchange chromatog. (HPAEC) anal. Furthermore, functional properties anal. showed that F-SDF exhibited higher water-holding capacity (WHC), oil-holding capacity (OHC), water solubility (WS) and cholesterol absorption capacity (CAC) than B-SDF. In summary, the present study suggested that SDF from defatted rice bran obtained through Trichoderma viride fermentation has a higher potential to be used as a functional ingredient in foods.

Gleditsia triacanthos polysaccharide, known as galactomannan, has not been exploited as a new functional material even though it possesses industrial potential in food and biomedicine. Galactomannans were recovered from the endosperm of seeds (15 wk to 25 wk after flowering) for deposition and maturation anal. These galactomannans were characterized by using NMR (NMR), X-ray diffraction (XRD), and monosaccharide composition anal. (particularly the mannose to galactose ratio) and mol. weight, solubility, and rheol. measurements. The ratio of the three parts in mature seeds was as follows: endosperm (36.67%), hull (34.41%), and embryo (28.92%). The M/G ratio increased from 2.53 to 3.24 between 15 and 23 wk and then decreased to 3.16 in 25 wk, consistent with the trends of rheol. and solubility The mol. weight (1.28 × 106 g/mol) and intrinsic viscosity (882.53 mL/g) reached the maximum at 23 wk and then decreased. Addnl., NMR and XRD showed that the M/G ratio did not change the basic chem. structure but caused slight changes in crystallinity. The purpose of the study was to reveal the changes in galactomannan structure, rheol., and solubility during G. triacanthos galactomannan deposition and maturation to facilitate exploration of its potential industrial applications.

Guo, Qingwen published the artcileHypoglycemic effects of polysaccharides from corn silk (Maydis stigma) and their beneficial roles via regulating the PI3K/Akt signaling pathway in L6 skeletal muscle myotubes, SDS of cas: 59-23-4, the main research area is Maydis stigma polysaccharide hypoglycemia alpha glucosidase skeletal muscle cell; Corn silk polysaccharides; Hypoglycemia; L6 myotubes; PI3K/Akt signaling pathway.

In the present study, the physicochem. properties of polysaccharides from corn silk (CSP) with different mol. weights were characterized and their inhibitory actions against α-glucosidase and α-amylase were evaluated. Then their effects on glucose uptake and mechanism of action in PI3K/Akt signaling pathway were also determined in L6 skeletal muscle cells. Results demonstrated that CSP could significantly inhibit a-amylase and a-glucosidase. CSP were non-toxic and they considerably increased the 2-NBDG uptake (P < 0.05) in L6 cells. Addnl., CSP regulated the PI3K/Akt signaling pathway and promoted the translocation of GLUT4 to the plasma membrane that would enhanced the glucose uptake in rat L6 skeletal muscle cells. Among the tested polysaccharides, CSP2 with the mol. weight of 62.16 kDa exerted appreciable hypoglycemic activity. Altogether it was suggested that CSP could be the promising candidate in the treatment of Type 2 Diabetes Mellitus (T2DM). The elucidation of the potential anti-diabetic mechanism of the polysaccharides from corn silk will facilitate their utilization in the functional food industries.
