Cytotoxic activity of Ormenis eriolepis organic extracts and fractions in a panel of cancer and nontransformed cell lines. A. suspension cells panel Jurkat, Jeko-1, and TK-6 and B. adherent cells panel LN229, SW620, U2OS, PC-3 and NIH3T3; were incubated for 48 h with 50 μg/ml of each extract and fraction. Results represent the mean ±SD of at least 3 independent experiments indicating the percentage of viable cells relative to vehicle-treated (control) cells. Statistically significant differences are indicated by ***p < 0.005 compared with untreated.
