Antiobesity Potential of Bioactive Constituents from Dichloromethane Extract of L. Seeds.

Purpose: Effectively controlling the accumulation of adipose tissue can be a therapeutic strategy for treating obesity, which is a global problem. The present study was designed for comparative assessment of antiobesity activities of the -dichloromethane seed extract (DCME) and the isolated phytochemicals, bakuchiol, isopsoralen, and psoralen, through antiadipogenesis and pancreatic lipase (PL) inhibition assays. pancreatic lipase activity was determined spectrophotometrically by measuring the hydrolysis of -nitrophenyl butyrate (-NPB) to -nitrophenol at 405 nm, and adipogenesis was assayed in 3 T3-L1 adipocytes (by using Oil Red O staining) using -dichloromethane seed extract (DCME) and individual compounds, isolated from the extract.

Result: Antilipase as well as antiadipogenesis activity was displayed by both the DCME and the compounds. Maximum antilipase property was recorded in DCME (26.02 ± .041%) at 100 g/ml, while, among the isolated compounds, bakuchiol exhibited a higher activity (24.2 ± 0.037%) at 100 g/ml concentration, compared to other isolates. DCME was found to exhibit antiadipogenesis property, 75 ± 0.003% lipid accumulation, compared to the control at 100 g/ml dose. Bakuchiol, isopsoralen, and psoralen inhibited the lipid accumulation in 3T3-L1 preadipocytes, 78.06 ± 0.002%, 80.91 ± 0.004%, and 80.91 ± 0.001%, respectively, lipid accumulation in comparison to control at 25 M dose.

Conclusion: The present study highlights the antiobesity potential of and its active constituents. Thus, it can be concluded that has the potential to treat obesity and related diseases; however, further research on dose standardization and clinical trials are required.
