Improvement of phenylethanoid glycosides production by a fungal elicitor in cell suspension culture of Cistanche deserticola

Abstract

When, on the 15th day of growth, an elicitor from Fusarium solani was added at 40 mg l⁻¹ to Cistanche deserticola cell suspension cultures, the contents of echinacoside, acteoside and total phenylethanoid glycosides (PeGs) in cultured cells all increased over the next 27 d by over 100% to 15 mg g⁻¹ dry wt, 9 mg g⁻¹ dry wt and 57 mg g⁻¹ dry wt, respectively. The final biomass (1.3 mg dry wt ml⁻¹) was not affected.
