FIGURE 4.

Trans-resveratrol accumulation in the culture medium of PE-treated cells. Cell suspensions, adjusted to 0.1 g FWC mL⁻¹, were treated with PE (0.5 g L⁻¹), or equal volumes of cons. agents or water. The culture medium was collected by vacuum filtration. Quantification of trans-resveratrol was performed by HPLC analysis and results correspond to the mean ± confidence interval of three independent biological repetitions. Significant differences (p ≤ 0.05) were identified with Kruskal–Wallis coupled with Dunn’s multiple comparison test. Conditions with different letters are significantly different.
