Abstract

Administration of an aqueous methanol/water extract of the Oriental crude drug “maō” (Ephedra), Ephedra distachya herbs, caused transient hyperglycemia followed by long lasting hypoglycemia in mice. Activity-guided fractionation of the extract led to isolation of five glycans, ephedrans A, B, C, D and E, which exhibited significant hypoglycemic effects in normal and alloxan-induced hyperglycemic mice.
