Effect of clove on improving running ability in aging mice.

In this study, a D‐galactose‐induced aging mouse model was established, and Syringa oblata Lindl. extract (SOLE) was administered orally to observe the effect and mechanism of SOLE on the running ability of aging mice. The role of SOLE was evaluated by H&E histopathological observation, detection of serum biochemical indices, and detection of mRNA expression levels by qPCR experiments. The experimental results showed that SOLE could increase the exhaustive running time of aging mice and reduce the oxidative aging of the liver and kidney. At the same time, the levels of BUN, lactic acid, GOT, GPT, MDA, iNOS, and TNF‐α in the serum of the mice were decreased, and the relative mRNA expression levels of nNOS, iNOS, TNF‐α and syncytin‐1 in the liver tissue and skeletal muscle tissue of the mice were downregulated. In addition, it increased the levels of CAT, GSH‐Px, and T‐SOD in mouse serum and upregulated the relative mRNA expression of Cu/Zn‐SOD, Mn‐SOD, and CAT in mouse liver tissue and muscle tissue. The analysis results showed that SOLE mainly contained rutin, isoquercitrin, ferulic acid, dihydroquercetin, and quercitrin. In summary, SOLE can enhance the running ability and exercise ability of aging mice and slow down aging. Practical applications: Clove is used as health tea or traditional Chinese medicine in China, but there is no relevant research and application on the improvement of human exercise ability. This study found this new function of clove, which accumulated a theoretical basis for further popularizing its application. [ABSTRACT FROM AUTHOR]
