AHB | 14.3 | 177.0 | 12.4 | 134.5 |
Water fraction | 27.7 | 106.6 | 3.8 | 136.7 |
Sulforaphane (μM) | 1.17 | 14.96 | 12.8 |
The highest limit of test concentration was 200 μg/mL. If the extract had no cytotoxicity, 200 μg/mL was used to calculate the CI value.
CD, concentration required to double QR activity; IC50 concentration required to inhibit cell growth by 50%; CI (chemoprevention index)=IC50/CD; AHE, ethanolic extract of Adenocaulon himalaicum; AHB, butanolic fraction of AHE; QR, quinone reductase.
