Abstract: Cell cultures of Pueraria tuberosa were established in modified Murashige and Skoog medium and challenged with yeast extract (YE), methyl jasmonate (MeJA) and salicylic acid (SA). Maximum isoflavonoids production was recorded at 48 h of YA incorporation at the stationary phase. 20 μM of MeJA and SA was most effective in isoflavonoids induction. Higher concentrations of these elicitors were negatively correlated with the isoflavonoids production. YE at 150 mg L⁻¹ was optimal for isoflavonoids production, yielding 10 mg L⁻¹ isoflavonoids, which was ~20% higher over the yields at optimal concentrations of MeJA and SA. YA incorporation can be used as a trigger to induce high yield of isoflavonoids.
