Mechanistic Insights into Polyphenol Oxidase Inhibition by Four Bioactive Constituents from Hydrangea macrophylla Serrata: Antioxidant Activity of Single Compounds Compared to the Whole-Leaf Extract

Hydrangea macrophylla serrata (tea-hortensia) leaves are traditionally used to produce a sweet herbal tea (“Amacha”) and contain hydroxycinnamates and dihydroflavonols with potential bioactivities (e.g., anti-inflammatory, anti-allergy). In this study, from an extract of tea-hortensia leaves, we isolated and structural...
