Abstract

Cyclocodon lancifolius fruit is a promising commercial fruit with antioxidant activity and is rich in polyphenolic compounds. In this study, the anti-aging activity of C. lancifolius fruit extract (CF) on Caenorhabditis elegans (C. elegans) was evaluated by observing the longevity, stress response, reproduction, oscillation, lipofuscin, and antioxidant enzymes of worms. Moreover, the effects and potential mechanisms of CF on delaying C. elegans senescence at the mRNA and metabolite levels were investigated. The results showed that CF treatment significantly increased the lifespan and stress resistance, decreased the levels of lipofuscin and reactive oxygen species (ROS), and improved the antioxidant system of C. elegans. The extension of the lifespan of C. elegans was remarkably correlated with the upregulation of mtl-1 and Hsp-16.2, along with the downregulation of age-1, daf-2, and akt-1. Metabolomics analysis revealed that purine metabolism is a key regulatory pathway for CF to exert anti-aging effects. The present study suggests that C. lancifolius fruit has potential for use as a functional food to enhance antioxidant capacity and delay aging.
