Resveratrol Production from Hairy Root Cultures of Scutellaria baicalensis

The levels of resveratrol produced by hairy root cultures of Scutellaria baicalensis were investigated using different media of varying strengths and in the presence of various concentrations of auxins. The levels of resveratrol were higher when the hairy root cultures were maintained in full-strength Murashige and Skoog (MS) medium when compared with other growth media. The cultures grown in full-strength MS medium produced 2.5-fold higher resveratrol than those grown in half-strength B5 medium the lowest resveratrol-producing medium. The levels of resveratrol varied significantly when cultures were grown in full-strength MS with varying concentrations of auxins. Supplementation of the media with the auxin indole acetic acid (IAA) at 0.1 mg/L produced the highest accumulation of resveratrol. Our findings reveal a valuable alternative approach for the production of resveratrol from S. baicalensis.
