Antidiabetic,hypolipidemic and histopathological analysis of Dillenia indica (L.) leaves extract on alloxan induced diabetic rats

Objective:To investigate antidiabetic,hypolipidemic histopathological analysis of Dillenia indica(D.indica) methanolic leaves(DIME) extract in alloxan induced diabetic rat by administering oral doses(250 and 500 mg/kg body weight).Methods:Blood glucose levels were measured using blood glucose test strips with elegance glucometer on weekly intervals till the end of study(i.e.3 weeks).Other parameters e.g.liver profile,renal profile and total lipid levels were determined in normal and alloxan induced diabetic rats after oral administration of the extract for 21 days.Histopathological changes in diabetic rat organs(pancreas,liver and kidney) were also observed after extract treatment Results:Daily oral administration DIME(250 and 500 mg/kg body weight) and glibenclamide(10 mg/kg) showed beneficial effects on blood glucose level (P【0.001) as well as improving kidney,liver functions and hyperlipidaemia due to diabetes. The extract treatment also showed to enhanced serum insulin level and body weight of diabetic rats as compared to diabetic control group.Furthermore,the extract has a favorable effect on the histopathological changes of the pancreas,liver and kidney in alloxan induced diabetes. Conclusions:D.indica possess antidiabetic property as well improve body weight,liver profile, renal profile and total lipid levels.DIME has also favorable effect to inhibit the histopathological changes of the pancreas and kidney in alloxan induced diabetes.

Microscopic evaluation and physiochemical analysis of Dillenia indica leaf

Objective:To study detail microscopic evaluation and physiochemical analysis of Dillenia indica(D.indica)leaf.Methods:Fresh leaf sample and dried power of the leaf were studied macroscopically and microscopically.Preliminary phytochemical investigation of plant material was done.Other WHO recommended parameters for standardizations were also performed.Results:The detail microscopy revealed the presence of anomocytic stomata,unicellular trichome,xylem fibres,calcium oxalate crystals,vascular bundles,etc.Leaf constants such as stomatal number,stomatal index,vein-islet number and veinlet termination numbers were also measured.Physiochemical parameters such as ash values,loss on drying,extractive values,percentage of foreign matters,swelling index,etc.were also determined.Preliminary phytochemical screening showed the presence of steroids,terpenoids,glycosides,fatty acids,flavonoids,phenolic compounds and carbohydrates.Conclusions:The microscopic and physiochemical analysis of the D.indica leaf is useful in standardization for quality,purity and sample identification.
