Hypoglycemic effects of <i>Ganoderma applanatum</i> and <i>Collybia confluens</i> exo‐polymers in streptozotocin‐induced diabetic rats

Abstract

The hypoglycemic effects of Ganoderma applanatum exo-polymer (GAE) and Collybia confluens exo-polymer (CCE) produced by submerged mycelial cultures in streptozotocin (STZ)-induced diabetic rats were investigated. Hypoglycemic effects were achieved in both the GAE- and CCE-treated groups by administration at a level of 100 mg/kg body weight (BW) daily for 3 weeks. The administration of GAE and CCE substantially reduced the plasma glucose levels by as much as 22.0% and 25.9%, respectively, when compared with the control group. The GAE and CCE also lowered the plasma total cholesterol and triglyceride levels by 20.3% and 22.5%, and by 22.7% and 25.5%, respectively. Furthermore, the activity of alanine transaminase (ALT) and aspartate transaminase (AST) was decreased by 23.2% and 20.7% in the GAE-treated group, and it was also reduced by 28.7% and 23.6% in the CCE-treated group. The results strongly demonstrate the potential of GAE and CCE in combating diabetes in experimental animals.
