Flavonoids are powerful antioxidants in vitro, but their overall functions in vivo have yet to be clarified, whether antioxidant, anti-inflammatory, enzyme inhibitor or inducer, or some other role. The reducing properties of flavonoids might also contribute to redox regulation in cells independently of their antioxidant properties. However, in order to understand their bioactivity in vivo, it is necessary to understand the factors influencing the absorption of flavonoids by the gastrointestinal tract, the nature of the conjugates and metabolites in the circulation and how this influences their antioxidant activities.

However, due to its poor solubility, bitter taste and poor oral bioavailability, the oral administration of tangeretin is still limited, which seriously limits its application in industrial production. The establishment of encapsulation and delivery systems to improve bioavailability is an effective method.

Black rice (BR) is beneficial for the health of animals and humans. Herein, we investigated the pharmacokinetics of cyanidin-3-glucoside (C3G), a major anthocyanin constituent of BR, in male rats. After its intravenous administration, C3G was rapidly distributed throughout the body and disappeared from the plasma.

Puerarin (PU), a bioactive constituent reported to possess therapeutic effectiveness, but it suffers a drawback of poor bioavailability. In the present study, the PU nanoparticles (PU-NPs) were prepared using solvent-diffusion-evaporation method and optimized using Box-Behnken design (BBD), a response surface methodology for obtaining the optimal material ratio of PU-NPs. Further, PU and PU-NPs were evaluated to assess their cytotoxic effect and in vitro efficiency of inflammatory responses using lipopolysaccharide-sensitive macrophage cell line (RAW264.

Inflammation, driven by various stimuli such as pathogens, cellular damage, or vascular injury, plays a central role in numerous acute and chronic conditions. Current treatments are being re-evaluated, prompting interest in naturally occurring compounds like kaempferol, a flavonoid prevalent in fruits and vegetables, for their anti-inflammatory properties. This study explores the therapeutic potential of kaempferol, focusing on its ability to modulate pro-inflammatory cytokines and its broader effects on inflammatory signaling pathways.
