Description

Abstract The effects of the components of Murashige-Skoog (MS) medium on the production of the diterpenes cryptotanshinone and ferruginol in cell suspension cultures of Salvia miltiorrhiza were examined. Sucrose, a nitrogen source and thiamine were needed for the production of these compounds, and phosphate, MnSO 4 and kinetin showed slight beneficial effects. All the other components of MS medium were found to be either unnecessary or inhibitory for the production of these compounds, when tested separately. A revised medium for the production of cryptotanshinone, a clinically active principle in this plant, was designed.
