Significant role of Bioactive compounds of Ganoderma lucidum in the aging process

Ganoderma lucidum, commonly known as Reishi or Lingzhi, is a medicinal mushroom widely recognized for its therapeutic potential in promoting health and longevity. Aging is a multifactorial process driven by oxidative stress, chronic inflammation, mitochondrial dysfunction, and immune decline. Bioactive compounds present in G. lucidum, such as polysaccharides (particularly β-D-glucans), triterpenoids (ganoderic acids), peptides, sterols, and phenolic compounds, exhibit potent anti-aging properties through diverse mechanisms. Polysaccharides enhance antioxidant defences, reduce free radical accumulation, and modulate immune responses, thereby delaying immunosenescence. Triterpenoids protect mitochondria, suppress pro-inflammatory signaling, and prevent apoptosis, contributing to neuroprotective and cardioprotective effects. Peptides and sterols further alleviate oxidative DNA damage, promote tissue repair, and maintain membrane stability, while phenolic compounds regulate cellular redox pathways and delay senescence. Experimental studies in animal and cell models have demonstrated that Ganoderma lucidum extracts improve lifespan, cognitive function, and stress resistance, supporting its role as a natural geroprotective agent. Moreover, its multi-targeted activity makes it a promising candidate in preventing age-related diseases, including neurodegeneration, cardiovascular disorders, and chronic kidney disease.
