Investigation of the Therapeutic Value of Verbascum pyramidatum Bieb. for Obesity

Abstract

Nowadays, one of the therapeutic approaches for obesity is the use pancreatic lipase inhibitors which reduce the digestion and absorption of fats. Most research indicates that natural sources which have a lipase inhibitory effect, may be utilized to treat obesity. Verbascum pyramidatum is one of the potential natural sources for obesity, and it has been demonstrated to have anti-inflammatory, antidiabetic, and regulatory effects on lipid metabolism. With this study, V. pyramidatum's potential lipase inhibitor effect, it is aimed to reveal its value in the treatment of obesity. In vitro spectroscopic method was used to determine the lipase inhibitory effect of V. pyramidatum. The quantitative investigation of V. pyramidatum's phenolic metabolites with antiobesity activity was carried out utilizing the Reverse Phase-High Performance Liquid Chromatography method. In this reported study, it was proven that extract and all fractions had an impact that inhibited lipase, with the ethyl acetate extract showing the highest inhibitory effect. Additionally, it was revealed through HPLC analysis that the species included p-OH benzoic acid, coumaric acid, quercetin, sinapic acid, and syringaldehyde. It has been demonstrated that V. pyramidatum may be a promising candidate for obesity treatment, but further investigations are required to use it as a therapeutic agent.
