Effects of (A) V. cornuta and (B) V. x wittrockiana extracts on lifespan of C. elegans SS104. Three replicates were used per treatment. The mean lifespan was 14 days in all groups, except in nematodes treated with 100 μg/mL was 12 days. Results of lifespan experiments were analysed using Kaplan–Meier survival model and for significance by means of a long rank pairwise comparison test between the control and treatment groups. Differences in survival curves between treatment and control groups were found in:(A) 25 *, 50 ***, and 250** μg/mL; (B): 250 (**) μg/mL. Differences compared to control group were considered significant at p ≤ 0.05 (*), p ≤ 0.01 (**) and p ≤ 0.001 (***).
