The hypothesized transformation action of the determined polyphenolic composition and the putative compounds of pomegranate leaf infusion during one-day storage. The relevant compounds were classified into hydrolyzable tannins (HTs), condensed tannins (CTs), flavonoids, and complex or oligomeric tannins. Polyphenolic compounds enclosed in dashed (or solid) boxes indicated decreased (or increased) concentrations. Reactions enclosed in green rounded rectangles indicated the possible transformation mechanisms between the compounds.
