Objective To analyze the impact of Poria cocos polysaccharides(PCP)on antioxidant and anti-aging effects in Caenorhabditis elegans and elucidate its potential mechanisms.Methods L4 stage C.elegans were randomly divided to low-,medium-,high-dose(10,20,40 μg/mL)PCP groups,and control group for cultivation.Anti-oxidant experiments,lifespan assays,lipofuscin determination,stress tests(UV/heat),and physiological function experiments(swallowing frequency/number of swings/egg-laying amount)were conducted to investigate the anti-oxidant and anti-aging...
