Obesity is an alarming sign and considered as a threat word wide. Since it not only hurt the human body but plays as a basis for other serious diseases like cardiovascular and many more. The 50% hydro-ethanolic extract of Dalbergia latifolia bark (D. latifolia) (DLBE; %yield = 16.34) and methanolic extract (4.32%) of D. latifolia were made. The DLBE was used for the acute oral toxicity and anti-obesity activity in the rodent. However, methanolic extract was used for characterization by high-performance thin layer chromatography (HPTLC) method. During acute toxicity study, it was shown that certainly there was no mortality or morbidity observed up to the maximum dose of 2000 mg/kg after administration of DLBE. The ultimate body weight, food intake, liver weight, total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), triglycerides (TG), aspartate aminotransferase (AST), alanine transaminase (ALT), serum creatinine and blood urea nitrogen (BUN) of rats treated with DLBE at a dose of 200 and 400 mg/kg respectively was considerably diminished to p < 0.01 and p < 0.05 as compared with high-fat diet (HFD) induced obese animals. However, DLBE treated with quite smaller dose revealed a non-significant (p > 0.05) effects on above parameters. The histopathological findings of the study from the cross section of liver and kidney show normal architecture in the cells treated with DLBE at a dose of 200 and 400 mg/kg respectively. Thus we can conclude that the bark extract of D. latifolia can be used for the treatment of obesity and a novel approach for further investigations of its pathology.
