“…Pharmacological research into A. cruentus has shown the presence of pectinic polysaccharides in the aerial parts of the plant, which give it cardioprotective and immunostimulating properties (Minzanova et al, 2014). Moreover, phytochemical research into red amaranth has revealed high levels of antioxidative compounds (phenolics, betacyanins, β-carotene, ascorbic acid), which points to the potential healing properties of this species (Mampholo et al, 2015;Li et al, 2015).…”

“…OSP was a densely cross‐linked network structure, forming flake voids; CSP showed round spherical aggregation. The primary structure of polysaccharides led to different spatial conformations (Minzanova et al ., 2014). The spatial conformation of OSP showed that it had less damage to its own helical structure during extraction (Kaya et al ., 2014).…”

This study aimed to investigate the effect of the extraction method on the physicochemical and structural properties of soy hull polysaccharide (SHP). Four types of SHP were extracted from soy hulls under the conditions of microwave-assisted oxalic acid (or citric acid) extraction and hot water extraction: MOSP, MCSP, HOSP and HCSP. The results showed the polysaccharide extraction rate of MOSP, HOSP, MCSP and HCSP was 11.97%, 8.99%, 6.22% and 4.74% respectively. SHP is mainly composed of arabinose, galactose, mannose and galacturonic acid, and the relative molecular weight range was 10 4 -10 6 Da. FT-IR showed that SHP contained hydroxyl, amido, ester, carboxyl and ether bonds. The fingerprints of SHP showed that the main chain composition and molecular weight of the four SHPs were similar, and the main constituent unit was 1,4-a-D-GalpA. In addition, the branched chains of polysaccharides contained 1,5-a-L-arabinoside bond, b-1,4-mannoside bond and b-1,4-galactoside bond.

“…The contents of uronic acid in WBP were determined by the sulfuric acid‐m‐hydroxybiphenyl method (Minzanova et al., 2014; Sosnina et al., 2000). The contents of total sugar were measured by using the traditional phenol‐sulphuric acid method (Dubois et al., 1951).…”

In this study, the structure and pro‐inflammatory activities of water‐soluble wheat bran polysaccharides (WBP) were evaluated. WBP were heteropolysaccharides consisting 60.34% arabinoxylan as the main component and 31.80% mannose residues characterized with the instrumental analyses. The result of cellular experiment displayed that WBP had significant pro‐inflammatory activities by increasing the concentration of nitric oxide (NO) and up‐regulating the inflammatory cytokine expressions of inducible nitric oxide synthase (iNOS), interleukin‐1β (IL‐1β), cyclooxygenase‐2 (COX‐2), and tumor necrosis factor‐α (TNF‐α). WBP mediated macrophages RAW 264.7 pro‐inflammatory response through phosphatidylinositol 3 hydroxykinase/protein kinase B (PI3K/Akt) signaling pathway by significantly promoting Akt and phosphoinositide‐dependent kinase 1 (PDK1) phosphorylations. Meanwhile, the expression of related phosphorylated proteins JNK and ERK1/2 was significantly up‐regulated which suggested that WBP played pro‐inflammatory roles by activating mitogen‐activated protein kinases (MAPKs) signaling pathway. Practical applications In recent years, wheat bran generally has the phenomenon of high yield and low utilization rate. Wheat bran has rich nutritional value and contains a lot of effective biologically active substances. Based on our findings, the water‐soluble polysaccharides extracted from wheat bran have significant effects on regulating immunity and can be utilized as sources of natural immune modulators. The research can develop new functions of wheat bran polysaccharides, and improve processing utilization rate and product added value.
