Ultrafiltration isolation, hypoglycemic activity analysis and structural characterization of polysaccharides from Brasenia schreberi

Brasenia schreberi (B. schreberi) is a rare and precious vegetable, which coat with a gelatinous mucilage. This study is aiming to investigate the relationship between structural characteristics and hypoglycemic activities of polysaccharides with different molecular weight (Mw) range. Three polysaccharides fractions, namely BSP-U100 (50–100 kDa), BSP-U50 (10–50 kDa) and BSP-U10 (<10 kDa), were isolated from B. schreberi mucilage using...
