Glutathione sulfotransferase inhibition activity of a self-fermented beverage, Kanji

Figures & data

Figure 1. Glutathione sulfotransferase inhibition activity of control, tannic acid and different concentrations of Kanji, prepared from the roots of Daucus carota L. Each bar is a mean of three independent experiments ± SD. *(significant difference from positive control, p < 0.05).

Figure 2. Glutathione sulfotransferase inhibition activity of control, tannic acid and different concentrations of methanol extract of the roots of Daucus carota L. Each bar is a mean of three independent experiments ± SD. *(significant difference from positive control, p < 0.05).
