The effects of Buddleja scordioides (BsLI) leaf infusions on digestive enzymes and carbohydrate absorption were evaluated. The BsLI yield was 21.64 %. In addition, a chemical characterization was carried out identifying hydroxybenzoic acids, hydroxycinnamic acids, flavonols, flavanones and flavones. In vitro studies were performed to determine the inhibitory action of BsLI on lipase, α-amylase, and α-glucosidase. Then, in rats, oral starch tolerance tests (OSTT) were carried out using BsLI at a dose of 9.5 mg/kg body weight. Results showed moderate inhibition of lipase and α-glucosidase, but greater inhibition of α-amylase compared to positive controls. During the OSTT trial, the group receiving BsLI showed a significant reduction in glucose levels compared to the negative control group. Bioactive compounds, such as naringenin, luteolin, quercetin, and coumaric acid, were identified after BsLI administration. Furthermore, the consumption of BsLI was safe and showed antioxidant activity like Trolox. In conclusion, BsLI may have an enhanced effect on glucose metabolism by inhibiting carbohydrate absorption.
