The Clerodendranthus spicatus (Thunb.) C. Y. Wu extract (CSTCYWE) was administered to D-galactose-induced aging mice to investigate the effect and mechanism of CSTCYWE on exercise endurance in aging mice. The effect of CSTCYWE on the improvement of exercise capacity in aging mice was evaluated by detecting serum biochemical indicators, pathological changes in tissues, and expression by qPCR. The composition of CSTCYWE was analyzed by HPLC. The experiment showed that CSTCYWE increased the running time and the exhaustive swimming time of aging mice to improve their exercise endurance. CSTCYWE also reduced the levels of BUN, BLA, and MDA and increased the levels of HG, MG, SOD, and GSH-Px in the serum of aging mice. Pathological observation found that CSTCYWE alleviated the liver and kidney tissue lesions and damage caused by aging. Meanwhile, CSTCYWE could down-regulate the relative mRNA expressions of nNOS, iNOS, TNF-α, and syncytin-1 and up-regulate the relative mRNA expressions of Cu/Zn-SOD, Mn-SOD, and CAT in the mouse liver tissue and skeletal muscle tissue. The results of component analysis showed that CSTCYWE contained caffeic acid, hypericin, isoquercetin, dihydroquercetin, rosmarinic acid, baicalin, luteolin, and baicalein. These active ingredients enable CSTCYWE to act on aging mice and improve their exercise capacity.
