From: Anti-influenza virus effect of aqueous extracts from dandelion
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%.
