Arundinin is primarily used in traditional medicine and phytochemical research due to its natural occurrence in plants like Arundo donax. It exhibits antioxidant properties, making it valuable in formulations aimed at reducing oxidative stress. Its structural similarity to certain bioactive flavonoids allows it to be studied for potential anti-inflammatory and antimicrobial effects. Researchers also explore its role in plant defense mechanisms, which can inform agricultural strategies for developing pest-resistant crops. Additionally, arundinin serves as a reference compound in chromatographic analysis of plant extracts, aiding in the identification of related glycosides and phenolic derivatives.
