Table 2 shows that the cell suspensions and root cultures also exhibited a higher level of α-glucosidase inhibition (IC50 = 0.11±0.01 mg DW/mL, 86±0.9 ng DW/mL and 0.34±0.02 mg DW/mL, respectively) and tyrosinase inhibition compared with intact root (IC50 = 0.70±0.05, 0.76±0.06 and 3.20±0.19 mg dry weight/mL, respectively).
