Abstract (original English)

Adipose tissue serves as a critical metabolic and endocrine organ, essential for maintaining systemic energy homeostasis and inter-organ communication. During the aging process, it undergoes significant structural remodeling and functional decline, characterized by dysregulated lipid metabolism, chronic low-grade inflammation, reduced insulin sensitivity, and adipokine imbalance. These alterations not only compromise the physiological integrity of adipose tissue but also contribute to the progression of various age-associated metabolic disorders, including type 2 diabetes, atherosclerosis, and nonalcoholic fatty liver disease. In recent years, natural products have emerged as a focal point in anti-aging research, owing to their broad accessibility, high biological safety, and capacity for multi-target regulation. Polyphenolic and polysaccharide, in particular, have demonstrated robust antioxidant, anti-inflammatory, autophagy-modulating, and mitochondrial-protective effects in cellular and animal models, indicating their promise in attenuating adipose tissue aging. Although the anti-aging effects of these natural compounds are well documented in the neural, hepatic, and cardiovascular systems, their specific mechanisms in adipose depots-especially differential regulatory patterns between white and brown adipose tissues, which may inform depot-specific therapies-and the developm
