Abstract:
The present study has been undertaken to evaluate the in-vitro, in-vivo and ex-vivo anti-diabetic activity of leaves of chloroform extract Clerodendrum paniculatum (CECP). The extract was prepared by soxhlet extraction. Phytochemical screening indicates the presence of flavonoids, phenols, carbohydrates etc. The anti-diabetic activity of extract was studied by in-vitro (alpha amylase inhibition and alpha glucosidase inhibition assay), in-vivo (streptozotocin induced diabetes) and ex-vivo (glucose uptake by rat hemi - diaphragm method). For in-vitro studies, the inhibitory action of CECP was compared with standard drug Acarbose. The IC50 values of CECP for alpha amylase and alpha glucosidase was found to be 158.396 µg/ml and 113.122 µg/ml respectively and the extract shows significant anti-diabetic activity. For in-vivo and ex-vivo studies Glibenclamide was used as a standard drug to compare the blood glucose level and uptake of glucose was calculated. The results obtained from the study indicate that both 200 mg/kg and 400 mg/kg of CECP showed significant anti-diabetic activity. The 400 mg/kg of CECP showed better activity when compared to 200 mg/kg of the extract. The glucose uptake study was performed by isolated rat hemidiaphragm method. The hemi diaphragm obtained from the rats treated with both the doses of CECP showed significant glucose uptake.
