Synthesis and antioxidant activity of selenium polysaccharide from Lotus root

Characteristics of selenium polysaccharide from sweet corncob and its effects on non-enzymatic glycosylation in vivo

“…This suggested that the SCP was successfully introduced into the selenium functional group. This was consistent with previous studies on pumpkin selenium polysaccharide [21] and pomegranate peel selenium polysaccharide [22].…”

Bioactive polysaccharides from lotus as potent food supplements: a review of their preparation, structures, biological features and application prospects

“…Mw reflects the polymerization of polysaccharides, whose detailed elucidation is crucial to study the physiological properties of polysaccharides ( 79 ). Conventionally, size exclusion chromatography (SEC), GFC, and gel permeation chromatography (GPC) were used to determine the Mw of LPs ( 52 , 59 , 62 , 74 ). Presently, GPC is most frequently used to detect the Mw of LPs.…”

“…The number-average Mw and weight-average Mw of LRP1 were 251,783 g/mol and 10,236 g/mol, respectively. The LPs were roughly grouped into neutral and acidic fractions, and the Mw distribution of LPs was relatively broad, ranging from 1.095 kDa to 578.09 kDa ( 32 , 74 ). In particular, the Mw of root LPs is relatively low.…”

“…For instance, the seed LPs (LSSP) exhibit significant immunomodulatory activity by stimulating the production of nitrous oxide (NO), interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α), in activated RAW 264.7 cells ( 50 ). Four root PLs (LP30, LP45, LP30, and LP60) induced the release of NO and enhanced the activity of macrophages ( 74 ). Song et al ( 76 ) investigated the mechanism of macrophage activation of crude leaf LPs (LLWP-C) and two derived ingredients (LLWP-1 and LLWP-3), which effectively improved the phagocytic and secretory effects of macrophages via upregulating the mitogen-activated protein kinase (MAPK) and nuclear factor κB (NF-κB) pathways.…”

“…Due to the ability to promote the growth of beneficial bacteria and stimulate the production of SCFAs ( 61 , 65 , 100 ), LPs hold promising potential as prebiotics in the food industry. Additionally, LPs exhibit significant immunomodulatory activity ( 16 , 74 ), making them a favorable food supplement for individuals with compromised immune function. Recent studies showed that lotus pectic polysaccharides possess characteristics that contribute to satiety and hinder digestion, rendering them suitable for the development of weight loss products ( 13 ).…”
