Effects of yeast elicitor on the growth and secondary metabolism of a hih-tanshinone-producing line of the Ti transformed Salvia miltiorrhiza cells in suspension culture

摘要

The effects of yeast elicitor on the cell growth and secondary metabolism of a high-tanshinone-producing line (cell line B) of the Agrobactrium tumefaciens C58 transformed Salvia miltiorrhiza cells were investigated in suspension culture. Application of yeast elicitor resulted in an overall increase (up to ca. 100/100) in cryptotanshinone production whereaes the constituent level of rosmarinic acid was reduced (from 2.6/100 of dry weight to zero at 1.0-ml elicitor dosage).
