Polysaccharides in Fungi. XXXVI. Hypoglycemic Activity of a Polysaccharide (CS-F30) from the Cultural Mycelium of Cordyceps sinensis and Its Effect on Glucose Metabolism in Mouse Liver

抄録

A polysaccharide (CS-F30) obtained from the cultural mycelium of Cordyceps sinensis showed potent hypoglycemic activity in genetic diabetic mice after intraperitoneal administration, and the plasma glucose level was quickly reduced in normal and streptozotocin-induced diabetic mice after intravenous administration. Administration of CS-F-30 to normal mice significantly increased the activities of hepatic glucokinase, hexokinase and glucose-6-phosphate dehydrogenase, although the glycogen content in the liver was reduced. Furthermore, CS-F30 lowered the plasma triglyceride level and cholesterol level in mice.
