The effect of geographic variation on chemical composition, antioxidant and hypoglycemic activities of Morus alba L. polysaccharides

Morus alba L. is an edible fruit with multiple medical function. To reveal the geographic variation pattern of polysaccharide content in the mulberry fruits and its antioxidant and hypoglycemic activities, the fruit samples were collected and analyzed from seven geographic locations throughout the distribution areas in China. The polysaccharide content in the mulberry fruits ranged from 4.13 ± 0.04% to 1.07 ± 0.07%. All the polysaccharides...
