Abstract:
Hyperlipidemia, characterized by aberrant lipid metabolism, constitutes a pivotal risk factor for cardiovascular diseases (CVDs) and contributes to various metabolic complications. Although conventional lipid-lowering agents are widely used, their long-term clinical application is frequently constrained by adverse side effects. Consequently, natural polysaccharides have attracted significant attention as promising therapeutic candidates due to their potent hypolipidemic effects and favorable safety profiles. This review systematically elucidates the underlying mechanisms by which natural polysaccharides ameliorate hyperlipidemia. Furthermore, the structure-activity relationships (SAR) are critically examined, with particular emphasis on how physicochemical properties such as molecular weight, monosaccharide composition, and chemical modifications modulate biological activity. Finally, current limitations and major bottlenecks in existing research are discussed, and future perspectives are proposed. Collectively, this review provides a reference for the development of novel polysaccharide-based therapeutics for the management of hyperlipidemia.
