title: Mechanisms of hypoglycemic activity of aconitan A, a glycan from Aconitum carmichaeli roots.
abstract: Aconitan A did not affect plasma insulin levels in normal, glucose-loaded and alloxan-induced hyperglycemic mice and gave no influence on insulin binding to isolated adipocytes. Aconitan A exerted no effect on the activities of hepatic hexokinase, glucokinase, glucose-6-phosphatase and glucose-6-phosphate dehydrogenase, whereas it significantly increased hepatic phosphofructokinase activity. Although the activity of hepatic glycogen synthetase showed a tendency to increase, the activity of liver phosphorylase and glycogen content were unchanged by aconitan A. Aconitan A did not change the total cholesterol and triglyceride contents of plasma and liver.
