bark is used in Mexican traditional medicine to treat chronic illnesses, including diabetes. For this reason, the purpose of this work was to evaluate the anti-hyperglycaemic effect of the aqueous extract from bark. Therefore, the aqueous extract at 40 mg/kg, administered orally and chronically, exhibited an anti-hyperglycaemic effect in a streptozotocin/nicotinamide model in Wistar rats. Because of our chemical study of this species demonstrated the presence of the coumarins xanthyletin (), luvangetin (), 8-hydroxyxanthyletin (), and methoxyrutaretin (), we also determined the presence of this bioactive compounds in the aqueous infusion and their quantification therein by developing a new, simple, fast, selective, sensitive, and precise HPLC-DAD method according to ICH validation guideline. Finally, the presence of coumarins can be associated with the anti-hyperglycaemic effect shown by the extract.

Dried blood spots (DBS) offer a practical and relatively non-invasive method for sample collection. Here, we evaluate the feasibility of applying H NMR spectroscopy to metabolomic analysis of DBS. Various solvent suppression techniques and extraction protocols were tested using aqueous and methanolic solvents.

These drugs inhibit the synthesis and release of prostaglandins (PGs) in the neurons of the anterior hypothalamus and exert therapeutic effects as a consequence. However, these drugs are relatively commonly misused and abused, often owing to a lack of proper medication guidance.
