Protective effect of Cassia glauca Linn. on the serum glucose and hepatic enzymes level in streptozotocin induced NIDDM in rats.
OBJECTIVE
The objective of the present study was to investigate the hypoglycemic and hepatoprotective effect of Cassia glauca leaf extracts on normal and non insulin dependent diabetes mellitus (NIDDM) in rats. The study was further carried out to investigate the effect of different fractions of the active extract of Cassia glauca, on normal and NIDDM rats, and the effect of active fraction on the blood glucose and hepatic enzymes level.


METHODS
Diabetes was induced by streptozotocin (STZ) at a dose of 90mg/kg, i.p. in neonates. Different extracts of cassia glauca (100mg/kg, p.o.) were administered to the diabetic rats. Acetone extract was found to lower the serum glucose level significantly in diabetic rats. Further, the acetone extract was subjected to column chromatography and four fractions were obtained on the basis of TLC. All the four fractions (100mg/kg, p.o.) were administered to the diabetic rats. Fraction 1 (F1) caused the maximum reduction in the blood glucose level. The results of the test were compared with the standard antidiabetic drug glibenclamide (5mg/kg, p.o.).


RESULTS
Fraction 1 of acetone extract caused a significant reduction in the levels of hepatic enzyme Aspartate transaminase (AST), alanine transaminase (ALT), creatine kinase (CK), and lactate dehydrogenase (LDH) in STZ-induced diabetic rats.


CONCLUSIONS
Improvement in the blood sugar level and normalization of liver functions by Cassia glauca indicates that the plant has hepatoprotective potential, along with antidiabetic activity, and it provides a scientific rationale for the use of Cassia glauca as an antidiabetic agent.
