HepG2 cells stained with oil red O after the treatment with Na-palmitate, Na-palmitate and artichoke leaf extract (25 µg/mL or 0.125% (v/v); 6.63 µmol/L rutin equivalents for “Violetto di Romagna”, 10.78 µmol/L for “Strunjanska articoka”, and 2.54 µmol/L for “Romanesco”) or artichoke leaf extract compared to control (non-treated cells). a denotes statistically significant (p < 0.05) difference between non-treated control cells and cells treated with specific extract; b denotes statistically significant (p < 0.05) difference between cells treated with Na-palmitate and cells treated with Na-palmitate and specific extract.
