Obesity is characterized by an excessive and abnormal accumulation of fat. According to the 2022 National Health and Nutrition Survey, in Mexico, the prevalence of overweight and obesity—diagnosed if one's body mass index (BMI) was ≥25 kg/m2—in adults was 75.2%. A strong association between the amount of visceral fat and diseases such as diabetes mellitus type II has been recognized. Species of the Bauhinia genus have lipid-lowering and antidiabetic properties. The aim of this work was to evaluate the lipolytic and antiadipogenic activity of Bauhinia divaricata L. in 3T3-L1 cells and to identify the major compounds in the bioactive treatments. The extraction of aerial parts allowed us to obtain hexanic (BdHex), ethyl acetate (BdEAc), and hydroalcoholic (BdHA) extracts. Lipid levels were measured in 3T3-L1 cells differentiated into adipocytes. Our evaluation of cell viability identified an IC50 > 1000 μg/mL in all the extracts, and our evaluation of the antiadipogenic activity indicated that there was a significant reduction (p < 0.001) in the accumulation of lipids with hydroalcoholic (60%) and ethyl acetate (75%) extracts of B. divaricate compared with metformin at 30 mM (65%). The major compounds identified in these extracts were as follows: triacetin (1), 2,3-dihydroxypropyl acetate (2), (3E)-2-methyl-4-(1,3,3-trimethyl-7-oxabicyclo[4.1.0]hept-2-yl)-3-buten-2-ol (3), 2,5-dihydroxyphenylacetic acid (4), (3R)-3-hydroxydodecanoic acid (5), kaempferol-3-O-rhamnoside (6), and quercetin 3-O-rhamnoside (7). Some of these naturally occurring compounds have been related to the anti-obesity effects of other medicinal plants; therefore, these compounds isolated from B. divaricata could be responsible for inhibiting the differentiation process from preadipocytes to mature adipocytes.
