Rhamnetin is primarily used in research settings for its biological activity, particularly its antioxidant and anti-inflammatory properties. It has been studied for potential applications in managing oxidative stress-related conditions, such as cardiovascular diseases and neurodegenerative disorders. Its ability to modulate cellular signaling pathways makes it of interest in cancer research, where it shows potential to inhibit the growth of certain tumor cells. Additionally, rhamnetin exhibits antimicrobial activity, suggesting possible use in developing natural preservatives or supportive agents in treating infections. Due to its natural occurrence in plants, it is also investigated for use in nutraceuticals and functional foods aimed at promoting overall health.
