Naringin (NG), a natural flavanone glycoside, possesses a multitude of pharmacological properties, encompassing anti-inflammatory, sedative, antioxidant, anticancer, anti-osteoporosis, and lipid-lowering functions, and serves as a facilitator for the absorption of other drugs. Despite these powerful qualities, NG’s limited solubility and bioavailability primarily undermine its therapeutic potential. Consequently, innovative solubilization methodologies have received considerable attention, propelling a surge of scholarly investigation in this arena. Among the most promising solutions is the enhancement of NG’s solubility and physiological activity without compromising its inherent active structure, therefore enabling the formulation of non-toxic and benign human body preparations. This article delivers a comprehensive overview of NG and its physiological activities, particularly emphasizing the impacts of structural modification, solid dispersions (SDs), inclusion compound, polymeric micelle, liposomes, and nanoparticles on NG solubilization. By synthesizing current research, this research elucidates the bioavailability of NG, broadens its clinical applicability, and paves the way for further exploration and expansion of its application spectrum.

Background: Amidst evolving modern lifestyles characterized by widespread circadian rhythm disturbances and high-fat dietary habits, the incidence of metabolic disorders continues to escalate. In recent years, plant-derived bioactive compounds have attracted considerable interest as therapeutic candidates, with quercetin and its derivatives demonstrating promising potential for the regulation of metabolism. Methods: This study employed a dual-induction model of metabolic dysregulation, elicited through both circadian rhythm disruption and a high-fat diet, to systematically evaluate the regulatory effects of quercetin and its derivatives on mice through dual stimulation by circadian rhythm disruption and a high-fat diet. Results and Conclusions: Non-targeted fecal metabolomics analysis indicates that quercetin and its derivatives significantly alter the intestinal metabolite profile in mice, alleviating metabolic abnormalities induced by circadian rhythm disruption and high-fat diet. These findings provide a theoretical basis for the future development of quercetin-based functional food products.
