Figure 2.

Antiproliferative effect in MDA-MB-231 cell viability of the lipid extracts of Ulva rigida, Codium tomentosum, Gracilaria gracilis, Palmaria palmata, Porphyra dioica and Fucus vesiculosus at five distinct concentrations. Control values obtained for cell culture without lipid extract correspond to cell viability of 100% and are not represented in the bar graphs. Values are presented as the average of three assays (n = 3) ± standard deviation (Tukey’s HSD post hoc analysis, p < 0.05). Different letters in the same graph represent significant differences among concentrations.
