Reviews on mechanisms of in vitro antioxidant, antibacterial and anticancer activities of water-soluble plant polysaccharides

Multi-crosslinking hydrogels with robust bio-adhesion and pro-coagulant activity for first-aid hemostasis and infected wound healing

“…As proposed, one possibility was that the TA can directly bind to the peptidoglycan on the wall of gram-positive bacteria, whilst the outer lipid membrane of gram-negative bacteria can prevent such binding. Secondly, the positive charges of the hydrogels conferred by the protonated amino groups stick firmly with the negatively charged gram-positive bacteria owning to the teichoic acid in the cell wall, which is absent in gram-negative bacteria, causing inadequate adhesion to the hydrogel [ 47 ]. For their natural origin, both CMCS and TA have inherent antibacterial properties to prevent the resistance caused by antibiotics to some extent [ 48 ].…”

Structural Elucidation and Antioxidant Activities of a Neutral Polysaccharide From Arecanut (Areca catechu L.)

“…Imbalance of reactive oxygen species could lead to many metabolic disorders and diseases, such as cancer, hypertension, and diabetes ( 49 ). It has been reported that plant polysaccharides could protect the body from oxidative damage ( 50 , 51 ). We evaluated the antioxidant activity of PAP1b in vitro by DPPH/hydroxyl radical scavenging, Fe 2+ chelating activity, and total reduction ability ( 21 , 52 , 53 ).…”

Phytochemicals and bioactivities of Goji (Lycium barbarum L. and Lycium chinense Mill.) leaves and their potential applications in the food industry: a review

“…Polysaccharide is structurally composed of homo or hetero monosaccharides and uronic acids connected with glycosidic linkages and are a very interesting component in phytochemical studies (Yarley et al, 2021). A large number of studies have been done focusing on extraction, purification and structural characterisation of L. barbarum polysaccharide (LBP) (Masci et al, 2018).…”
