Background: The methanolic extract of Convolvulus pluricaulis had earlier shown lipid lowering activity in Triton induced reversible hyperlipidemia model, but, the hypolipidemic activity in irreversible models and hypoglycaemic activity are not investigated so far. Objective: This study was designed to validate the lipid and glucose-lowering actions of C. pluricaulis methanolic extract (CPME) by using ingredients from the Indian diet for induction of hyperlipidemia and diabetes on experimental rats. Materials and methods: Experimental animals were divided into four groups having six animals in each group (n = 6). Animals of Group I II, III and IV received - no treatment, 0.9% NaCl, Glipizide (GPZ) 5 mg/kg and CPME 400 mg/kg once daily for two weeks respectively. Animals of all groups except group I were fed a high fat-based Indian diet for 21 days followed by a single STZ (35 mg/kg) i.p. administration in model induction phase. Afterwards, animals were sacrificed, and the pancreas was dissected for histological changes, and blood was collected for measuring lipid parameters, FBS, insulin levels, and HOMA scores. Results: CPME significantly ameliorate the lipid abnormalities in HFD-STZ-treated experimental model (p 0.05) as compared to experimental group while, GPZ showed protective effect on both lipid abnormalities and hyperglycemia by modulating the levels of lipid parameters and insulin respectively. Conclusion: In conclusion, the study confirm that CPME possesses significant hypolipidemic activity but fails to reverse the hyperglycaemia developed in diabetic rats.
