Delicaflavone is primarily used in pharmaceutical and nutraceutical research due to its strong antioxidant and anti-inflammatory properties. It shows potential in supporting cardiovascular health by improving endothelial function and reducing oxidative stress in blood vessels. Studies suggest it may help regulate lipid metabolism, making it a candidate for managing metabolic disorders such as hyperlipidemia. Additionally, its neuroprotective effects are being explored in the context of neurodegenerative diseases like Alzheimer’s, where oxidative damage plays a key role. Delicaflavone is also investigated for its antiviral activity, particularly against certain enveloped viruses, owing to its ability to interfere with viral entry into host cells. In cosmetic formulations, it is valued for protecting skin from environmental oxidative damage, helping to reduce signs of aging and improve skin elasticity. Its natural origin and low toxicity profile make it suitable for use in functional foods and dietary supplements aimed at promoting long-term health and wellness.
