- Abstract
Clerodendranthus spicatus (Thunb.) (Kidney tea) is a very distinctive ethnic herbal medicine in China. Its leaves are widely used as a healthy tea. Many previous studies have demonstrated its various longevity-promoting effects; however, the safety and specific health-promoting effects of Clerodendranthus spicatus (C. spicatus) as a dietary supplement remain unclear. In order to understand the effect of C. spicatus on the longevity of Caenorhabditis elegans (C. elegans), we evaluated its role in C. elegans; C. spicatus water extracts (CSw) were analyzed for the major components and the effects on C. elegans were investigated from physiological and biochemical to molecular levels; CSw contain significant phenolic components (primarily rosmarinic acid and eugenolinic acid) and flavonoids (primarily quercetin and isorhamnetin) and can increase the lifespan of C. elegans. Further investigations showed that CSw modulate stress resistance and lipid metabolism through influencing DAF-16/FoxO (DAF-16), Heat shock factor 1 (HSF-1), and Nuclear Hormone Receptor-49 (NHR-49) signalling pathways; CSw can improve the antioxidant and hypolipidemic activity of C. elegans and prolong the lifespan of C. elegans (with the best effect at low concentrations). Therefore, the recommended daily use of C. spicatus should be considered when consuming it as a healthy tea on a daily basis.
