This study aimed to evaluate the immunomodulatory effect of the polysaccharide from Sinonovacula constricta (SCP‐1‐1) in RAW264.7 cells. SCP‐1‐1 with a molecular weight of 440.0 kDa consisted of glucose and mannose. The immunomodulatory assay results showed that SCP‐1‐1 could significantly enhance phagocytic ability, NO production, and some cytokines (TNF‐α, IL‐6, and IL‐1β) secretion of RAW264.7 cell in a dose‐dependent manner. Western blot analysis results demonstrated that SCP‐1‐1 could regulate the expression levels of the key proteins in the signaling pathways of RAW264.7 cell and might associated with NF‐κβ and PI3K signaling pathway. These findings could contribute to elucidate the immunomodulatory activities of the polysaccharide from Sinonovacula constricta.

“…The differences between enzyme-assisted extraction and aqueous extraction were compared using UV-visible and IR spectroscopy. Interesting, the yield from enzymatic extraction was 12.26% higher than that of aqueous extraction ( 26 ). Enzymatic extraction can maintain the integrity of SCP and improve the yield of the polysaccharide as compared to traditional extraction methods.…”

Shellfish are diverse, widely distributed organisms that are a rich source of biological resources. Polysaccharides are an important components in shellfish, hence a great deal of attention has been directed at isolation and characterization of shellfish polysaccharides because of their numerous health benefits. Differences in shellfish species, habits, and environment result in the diversity of the structure and composition of polysaccharides. Thus, shellfish polysaccharides possess special biological activities. Studies have shown that shellfish polysaccharides exert biological activities, including antioxidant, antitumor, immune-regulation, hypolipidemic, antihypertensive, and antihyperglycemic effects, and are widely used in cosmetics, health products, and medicine. This review spotlights the extraction and purification methods of shellfish polysaccharides and analyses their structures, biological activities and conformational relationships; discusses the regulatory mechanism of shellfish polysaccharides on hyperlipidemia, hypertension, and hyperglycemia caused by lipid metabolism disorders; and summarizes its alleviation of lipid metabolism-related diseases. This review provides a reference for the in-depth development and utilization of shellfish polysaccharides as a functional food to regulate lipid metabolism-related diseases. To achieve high value utilization of marine shellfish resources while actively promoting the development of marine biological industry and health industry.

“…According to the position of the infrared absorption peak, the configuration of the glycosidic bond can be determined. The absorption band at 905-876 cm −1 was indicative of β-pyranose, and that at 848-810 cm −1 was indicative of α-pyranose (Huang et al, 2016;Yuan et al, 2019). The OCP fraction mainly contained β-pyranose, and the structure of OPP changed during purification and converted into α-pyranose.…”

Osmunda japonica (Thunb) is a plant with high nutritional and medicinal value (Li & Shah, 2014). Its main components are polysaccharides and flavonoids. Polysaccharides consist of monosaccharides linked by glycosidic bonds. Polysaccharides are a class of carbohydrates with complex molecular structures and large sizes that are widely distributed in nature (Xie et al., 2016). Osmunda japonica (Thunb) has antioxidation (Bowen et al., 2018), antibacterial (Dai & Lei, 2001), and anti-inflammatory functions (Zhu et al., 2013), among others. Moreover, this herb has the effect of relieving fevers, detoxifying the body, moistening lungs, increasing
