Structural Characterization and Hypoglycemic Effects of a Purified Polysaccharide From <i>Cinnamomum cassia</i>. [PDF]

Food Sci Nutr
CCP1A, a polysaccharide purified from Cinnamomum cassia with a molecular weight of approximately 8.16 kDa and rich in glucose and galacturonic acid, exerts anti‐type 2 diabetes effects through a multi‐target synergistic mechanism. On one hand, it delays intestinal glucose absorption by inhibiting the activities of α‐amylase and α‐glucosidase in the ...
