Antioxidative Stress and Anti-aging Effects of Lithocarpus litseifolius folium Based on Caenorhabditis elegans Model

In this study, the main components of the extract of (Lithocarpus litseifolius folium extract, LLFE) were analyzed,and the anti-oxidative stress and anti-aging effects of LLFE on C.elegans were evaluated using Caenorhabditis elegans (C.elegans) as a model to explore the possible mechanisms of action.The results showed that LLFE contained 52.84±1.45 mg/g of total phenols, 380.74±15.12 mg/g of total flavonoids, 470.36±5.84 mg/g of total sugars and about 6.00% of dihydrochalcone compounds, with phloridzin 52.76±0.71 mg/g, phloretin 1.64±0.06 mg/g and trilobatin 4.88±0.01 mg/g. LLFE (0.25, 1.25 mg/mL) also significantly extended the mean lifespan of C.elegans under oxidative and heat stress conditions (P
