 Title    Influence of Medium Composition on the Formation of Secondary Compounds in Cell Suspension Cultures of Catharanthus roseus (L.) G. Don  
 Abstract    Cell suspension cultures o f Catharanthus roseus have been subjected to various m edia condi­ tions in order to stim ulate the formation o f indole alkaloids. H igh ajmalicine contents (up to 0.5 m g/g cell fresh weight) were achieved by transferring 2-week-old cell suspensions to a 10-fold volum e o f a 8% sucrose solution. The alkaloid accum ulation started two days after the transfer and reached a plateau after ten days. Furthermore an enhanced level o f phenolic com pounds was found, whereas growth o f the culture was low. The accumulation o f both, alkaloids and poly­ phenols was stimulated by high concentrations o f sucrose and low concentrations o f nitrogen con­ taining salts and phosphate. W hen these m inerals were added to the sucrose solution in con­ centrations com m only used for cell culture m edia, the accum ulation o f alkaloids and phenolic compounds was largely suppressed.
