Fig. 11. The cumulative survival graph depicting the effect of EISO and its major active principles on the lifespan of 6-OHDA intoxicated N2 C. elegans. The 6-OHDA induced reduction in longevity was significantly attenuated with EISO, α- and β-santalol treatments (shown as turquoise blue, black and green survival curves, respectively). The data were processed using the Kaplan–Meir survival analysis and significance levels were estimated by long-rank test.
