Structural characterization, antioxidant activity and bioaccessibility of luteolin-gellan gum covalent complex via free radical-induced coupling.
Luteolin is a bioactive flavonoid with strong antioxidant activity, however, its applications are severely limited by poor water solubility, low chemical stability, and inadequate oral bioavailability. To address these challenges, this study aims to develop a covalent delivery system capable of simultaneously enhancing...
