Abstract A novel acid polysaccharide (PPRLMF-2) with the Mw of 137,123 Da and a triple-helix conformation was first isolated from the pulp of Rosa laevigata Michx fruit. Structural characterization showed that PPRLMF-2 consisted of rhamnose (7.6%), arabinose (26.5%), xylose (3.5%), mannose (0.9%), glucose (5.7%), galactose (31.9%) and galacturonic acid (23.9%). The methylation and NMR (1D and 2D) analysis revealed that PPRLMF-2 contained 16 types of glycosidic linkages. The immunomodulatory acti...

In a previous study a crude peptide extract was obtained from Dendrobium aphyllum, and this study focused on the functional characterization of the peptide fraction (named DPP) after being purified by DEAE Sepharose. The DPP with high purity contained 16 types of free amino acids and 6 polypeptides. DPP could act as the AAPH-free radical scavenger to protect the erythrocyte under oxidative stress, and the attenuation significantly increased after intestinal digestion. Moreover, the results of th...

Abstract A novel polysaccharide with a molecular weight of 12.3 kDa, was isolated from the root of Pueraria lobata (Willd.) Ohwi using cold water extraction method. Methylation analysis, Periodate oxidation, Smith degradation, and nuclear magnetic resonance analysis showed that 1,4-α-D-Glcp and 1,3,6-α-D-Glcp were the main linkage types of this polysaccharide. It exhibited immunomodulatory activity by enhancing the pinocytic and phagocytic capacities and promoting the secretion of nitric oxide, ...

Abstract A novel polysaccharide designated SLP-4 with the Mw of 19681 Da was purified from the petal of Saussurea laniceps. Monosaccharide composition analysis indicated that SLP-4 was composed of mannose, rhamnose, galacturonic acid, glucose, galactose, xylose and arabinose in a molar ratio of 0.825:2.030:14.998:0.841:8.260:4.039:6.009. Structural features indicated that SLP-4 was a typical pectin polysaccharide with a backbone containing →3,6)-Galp-(1→, →4)-GalpA-(1→, →6)-Galp-(1→, →4, 6)-Galp...

Neutrase-hydrolysates hydrolyzed from mulberry leaf proteins were separated by ion exchange chromatography, gel filtration chromatography, and semipreparative reverse-phase HPLC. Purified fractions were analyzed for their radical scavenging activity, hemolysis inhibition ability, and cellular antioxidant activity (CAA). Three new antioxidant peptides, P1 (SVL, 317 Da), P2 (EAVQ, 445 Da), and P3 (RDY, 452 Da), were obtained from the most active HPLC fraction (R1) and identified using UPLC-QTOF-MS...

To characterize the digestive properties of an antioxidative peptide fraction (DA-P peptide) extracted from Dendrobium aphyllum and its effects following fermentation, DA-P peptide was used as a substrate for artificially stimulated in vitro gastrointestinal digestion and fermentation by human fecal microbiota. After in vitro digestion, the reducing power and DPPH- and ABTS- free radical-scavenging capabilities of DA-P peptide were significantly improved. During fermentation, changes in pH, pept...

Maca protein isolate (MPI) was extracted from maca root, and its physicochemical and functional properties, and the secondary structure and immunomodulatory activity of its major protein component, MMP, were investigated. The MPI lacked essential amino acids compared with soybean protein isolate (SPI) and casein, but was rich in cysteine and proline. The MPI had rich free sulfhydryl (20.6 μmol g−1), and its surface hydrophobicity (H0, 812.4), oil absorption capacity (7.4 g g−1), foaming capacity...

The health‐promoting effects of a polysaccharide (DAP) purified from Dendrobium aphyllum, on mice colon were investigated. The results indicated that consumption of DAP facilitated the differentiation degree of CD4⁺ T cells to Th₁, Th₁₇ and Treg cells; and depressed the differentiation degree to Th₂ cells, since DAP up‐regulated IL‐6 expression (from 1.08 ± 0.24 to 3.40 ± 0.36). Besides, oral administration of DAP reduced the gastrointestinal transit time from 255 ± 1.21 to 164 ± 0.46 min, decre...

A polysaccharide, Ali-1, was isolated from the roots of Eurycoma longifolia, a popular traditional medicinal herb in Malaysia. The structure of Ali-1 was characterized by monosaccharide, methylation, and NMR data analyses. The average molecular weight of Ali-1 is 14.3 ku, and it is composed of arabinose (14.31%), xylose (57.69%), galacturonic acid (13.03%), and glucuronic acid (14.86%). The main chain comprises (1→4)-linked xylose residues. It has branch points in the main chain; (1→2,4)-linked ...
