The present study was aimed to evaluate the anti-diabetic potential of
Terminalia chebula (T. chebula) fruits on streptozotocin (STZ)-induced
experimental diabetes in rats.
Oral administration of ethanolic extract of the fruits (200 mg/kg body
weight/rat/day) for 30 days significantly reduced the levels of blood
glucose and glycosylated hemoglobin in diabetic rats. Determination of
plasma insulin levels revealed the insulin stimulating action of the
fruit extract.
Also, the alterations observed in the activities of carbohydrate and
glycogen metabolising enzymes were reverted back to near normal after
30 days of treatment with the extract.
Electron microscopic studies showed significant morphological changes
in the mitochondria and endoplasmic reticulum of pancreatic â cells of
STZ-induced diabetic rats.
Also, a decrease in the number of secretory granules of â-cells was
observed in the STZ-induced diabetic rats and a these pathological
abnormalities were normalized after treatment with T. chebula
extract.
The efficacy of the fruit extract was comparable with glibenclamide, a
well known hypoglycemic drug.
