Effect of green coffee (GC), roasted coffee (RC), and coffee silverskin (S) extracts (1 mg/mL) on: (A) Caco-2 cell viability, determined by quantification of extracellular LDH activity, and (B) culture growth, determined with the SRB assay. Cells were cultured for 24 h in the presence of GC, RC, and S extracts (n = 4–10) or the respective solvent (control; n = 8–10). The results are shown as arithmetic means ± SEM. *, significantly different from control (p < 0.05; Student’s t-test).
