title: Studies on tissue cultures of the genus Cinchona L. alkaloid production in cell suspension cultures.
abstract: Initiation and culture of callus and cell suspensions of Cinchona ledgeriana and C. succirubra as well as the successful isolation and selection of a high-yielding alkaloid-forming strain derived from the leaf rachis of a C. succirubra plant are described. Results of feeding experiments with L-tryptophan using two different culture procedures are presented and discussed. Maximum alkaloid yields of up to 0.9% (based on dry weight) or 6.35 mg/l have been obtained.
