Methods: The anti-lipase activity for ten plants was evaluated and compared with the reference compound Orlistat by using the porcine pancreatic lipase inhibitory test which was conducted by using a UV-visible spectrophotometer. Results: The aqueous extracts of Vitis vinifera and Rhus coriaria had the highest antilipase effects with IC50 values 14.13 and 19.95 mcg/mL, respectively. Meanwhile, the organic extract of Origanum dayi had an IC50 value 18.62 mcg/mL. V. vinifera showed the highest porcine pancreatic lipase inhibitory effects when compared with Orlistat, which has an IC50 value 12.38 mcg/mL. Conclusions: According to the obtained results, V. vinifera, R. coriaria, and O. dayi can be considered a natural inhibitors of the pancreatic lipase enzyme as well as new players in obesity treatment. In fact, these plants can be freely and safely consumed in a daily diet or can be prepared as nutraceutical formulations to treat or prevent of obesity. View Full-Text
