Separation, purification, and α-glucosidase inhibition of polysaccharides from Coriolus versicolor LH1 mycelia

► LH1 is a new strain of Coriolus versicolor. ► We have separated and purified three polysaccharides from C. versicolor LH1. ► These polysaccharides could be explored as a novel potential antidiabetic. ► These polysaccharides included triterpenoids and polyphenols compounds. ► The amount of glucose and α-(1,4) glycosidic linkages are related to α-glucosidase inhibition.
