Phytochemical Profile and α‐Amylase Inhibitory Activity of Pomegranate Peel Extract: An In Silico and In Vitro Investigation

Food Science &Nutrition, Volume 13, Issue 11, November 2025.
The graphical abstract illustrates a systematic workflow that begins with the extraction of bioactive compounds from pomegranate. LC–MS analysis identifies punicalagin, and molecular docking evaluates the binding of punicalagin to α‐amylase, followed by in vitro validation of its inhibitory activity.
