AI Technical Summary
Current research on the bioactivity of lotus bee pollen polysaccharides is relatively scarce, especially regarding their antioxidant, hypoglycemic, and anti-inflammatory properties, and there is a lack of effective extraction and purification processes.
Microwave-assisted extraction of lotus bee pollen polysaccharides was performed, combined with Sevag method for protein removal and DEAE-52 cellulose ion column chromatography. The extraction conditions were optimized to obtain low molecular weight polysaccharide LBPP-1, which is composed of arabinose, glucosamine hydrochloride, galactose and glucose, and has a β-configuration and triple helix structure.
Lotus bee pollen polysaccharide exhibits significant antioxidant capacity, scavenging DPPH, ABTS and hydroxyl free radicals, inhibiting AAPH-induced erythrocyte hemolysis, and possessing anti-inflammatory effects. In in vitro hypoglycemic experiments, it also showed inhibition of α-amylase and α-glucosidase activity.
