Percentage survival of untreated and extract-treated S. cerevisiae cells in presence of oxidative stressing agent (H₂O₂).

Treatment	% Survival^a
Untreated cells (control)	100±1.52
4 mM H2O2	26.80±0.58^b
H2O2 + 200 μg/mL extract	39.17±2.08^c
H2O2 + 400 μg/mL extract	65.98±1.15^c
H2O2 + 800 μg/mL extract	88.66±0.58^c

aAverage ± SD (𝑛=3). ^bSignificantly different from the untreated cells (control) by the analysis of variance (ANOVA) and Dunnett’s t-test (𝑃≤0.05). ^cSignificantly different from the stressing agents by the analysis of variance (ANOVA) and Dunnett’s t-test (𝑃≤0.05).
