Abstract
The shaddock ped polysaccharide (SPP) was extracted by ultrasound-assisted enzyme method. Phosphorylated shaddock ped polysaccharides (P-SPP) and acetylated shaddock ped polysaccharides (Ac-SPP) were obtained by chemical modification of SPP. The characterization methods such as infrared spectroscopy and nuclear magnetism were employed to characterize the structures of the two derivatives. The antioxidant activity of SPP and its derivatives was investigated by measuring their DPPH radical scavenging capacity, hydroxyl radical ion scavenging capacity and superoxide anion scavenging capacity. In comparison, P-SPP showed better antioxidant activity. The results indicated that the antioxidant activity of the polysaccharides varied with different chemical modifications.

Structural characterization and anti-inflammatory activity of neutral polysaccharides from American ginseng. Int J Biol Macromol 2023; 248:125586. [PMID: 37379950 DOI: 10.1016/j.ijbiomac.2023.125586] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 05/29/2023] [Accepted: 06/25/2023] [Indexed: 06/30/2023]
Abstract
American ginseng, a precious classic herbal medicine, is used extensively in China for life prolongation purpose. This study aimed to elucidate the structure and anti-inflammatory activity of a neutral polysaccharide isolated from American ginseng (AGP-A). Nuclear magnetic resonance in conjunction with gas chromatography-mass spectrometry were used to analyze AGP-A's structure, whereas Raw264.7 cell and zebrafish models were employed to assess its anti-inflammatory activity. According to the results, AGP-A has a molecular weight of 5561 Da and is primarily consisted of glucose. Additionally, linear α-(1 → 4)-glucans with α-D-Glcp-(1 → 6)-α-Glcp-(1→ residues linked to the backbone at C-6 formed the backbone of AGP-A. Furthermore, AGP-A significantly decreased pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α) in Raw264.7 cell model. AGP-A in zebrafish model significantly lower the massive recruitment of neutrophils to the neuromast of the caudal lateral line. Inflammation may be relieved by the AGP-A component in American ginseng based on these results. In conclusion, our study shows the structural characterization, remarkable anti-inflammatory properties of AGP-A and its potential curative efficacy as a safe, valid natural anti-inflammatory medicine.

Food Res Int 2022; 157:111444. [PMID: 35761684 DOI: 10.1016/j.foodres.2022.111444] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 05/20/2022] [Accepted: 05/26/2022] [Indexed: 11/04/2022]
Abstract
Low molecular weight sulfate glycosaminoglycan has attracted more attention recently for its great bioactivity. In the present study, a degraded sulfate glycosaminoglycan (named D-SBSG) was prepared from swimming bladder by enzymatic depolymerization, the structure characteristics of D-SBSG and its effects on blood coagulation and inflammation in vitro was investigated. HPGPC analysis showed that the molecular weight (Mw) of SBSG was 115.84 kDa, while the Mw of D-SBSG was 4.96 kDa. The bioactivities had arose dramatic differences, though its main molecule structure had little change after enzymatic degradation. Compared with heparin sodium, relatively milder anticoagulant activity in vitro, which were positively associated with molecular weight, were found in SBSG and D-SBSG. In contrast, the results of anti-inflammatory assays indicated that D-SBSG with the lower molecular weight possessed higher bioactivity than SBSG. Additionally, the D-SBSG inhibited the LPS-induced inflammatory in RAW264.7 macrophages by down-regulation of inflammatory mediators, both of NF-κB (including p65) and MAPK (including p38) signaling pathways to exert its anti-inflammatory function. These results indicated that enzymolysis is a viable strategy for degradation of sulfate glycosaminoglycan, and D-SBSG could be a promising ingredient for inflammation management.
