Cytotoxicity assay of dandelion extracts. (A) MDCK cells were left untreated (negative control) or treated with the indicated amounts of dandelion extracts or oseltamivir (2-fold dilutions) for 48 h. (B) MDCK cells were left untreated (negative control) or treated with 0.1 mg/ml oseltamivir, 2.5 mg/ml dandelion extracts and 15 mg/ml dandelion extracts (positive control) for 72 h. The cells were treated with CCK-8 solution (10 μl/well) and incubated for 4 h at 37°C. The absorbance was measured using a microplate reader at 450 nm. The untreated control was set at 100%.
