Effect of Thai Herbal Remedy NL Inhibits Lipid Accumulation on 3T3-L1 Adipocyte Cells.

Obesity is a global health concern, steadily rising and posing risks to various health conditions. Despite available antiobesity drugs, their withdrawal due to severe side effects highlights the need for safer alternatives. Natural products, particularly mixed herbal formulations, present a promising avenue in obesity research. This study aimed to investigate the potential antiobesity effects of the NL herbal formula, a traditional remedy in Nakhon Si Thammarat, Thailand, composed of nine herbs. The specific focus was on the inhibitory effects on -glucosidase and pancreatic lipase enzyme activities, adipogenesis inhibition and lipolysis promotion. NL extract was phytochemically analyzed and assessed for its inhibitory effects on -glucosidase and pancreatic lipase. Its impact on lipid accumulation and glycerol release was also evaluated. Phytochemical analysis using liquid chromatography-tandem mass spectrometry (LC/MS-MS) identified piperine as the major compound in the NL extract. NL extract exhibited significant inhibition of -glucosidase, moderate pancreatic lipase inhibition, and dose-dependent reduction in fat accumulation and triglyceride content. Glycerol release increased compared to the control, indicating potential benefits in weight management. This research underscores the potential of the NL formula in combating obesity through its effects on adipogenesis, lipolysis, and enzyme activities. Further investigations into the molecular mechanisms are warranted to fully elucidate its therapeutic potential.
