Implication

In vivo experiments show Glehniae Radix polysaccharides reduce blood glucose levels in diabetic mice, suggesting PPAR signaling involvement.

Key Points

This research aims to assess the hypoglycemic effects of Glehniae Radix polysaccharides in a diabetic mouse model and elucidate underlying mechanisms.
Extracted GRP using water extraction and ethanol precipitation.
Administered GRP at 300 and 600 mg/kg doses in female db/db mice for five weeks.
Measured fasting blood glucose, insulin tolerance, cholesterol, and triglyceride levels post-treatment.
GRP treatment led to a 40.7% reduction in fasting blood glucose.
Insulin tolerance improved by 28.4% in treated groups.
Cholesterol and triglyceride levels decreased by approximately 40.8% and 24.6%, respectively.
Increased expression of Zonula Occludens-1 by 49.5%.
Enhanced PPAR-α and PPAR-γ expression noted, along with changes in gut microbiota composition.
