Cytotoxicity of the Tanaceti flos and Tanaceti folium aqueous extracts and Ag-NPs obtained in green synthesis.
| The Investigated Sample | Cell Line | SI | |
|---|---|---|---|
| Vero | HeLa | ||
| CC50 (µg mL−1) a | |||
| Tanaceti flos extract | 596.6 ± 6.0 | 681.0 ± 6.0 | 0.9 |
| Tanaceti folium extract | 861.3 ± 102.5 | 753.1 ± 46.3 | 1.1 |
| Tanaceti flos Ag-NPs | 22.1 ± 5.4 | 67.3 ± 0.2 | 0.3 |
| Tanaceti folium Ag-NPs | 14.1 ± 0.3 | 57.9 ± 3.3 | 0.2 |
Abbreviations: The CC50 is the cytotoxic concentration required to reduce the number of viable cells by 50%; SI = CC50 of the tested extract in normal Vero cell line/CC50 of the tested extract in a cancer cell line; a mean ± S.D. values come from two independent experiments.
