Alkaloid Production by Leaf Organ, Root Organ and Cell Suspension Cultures of Cinchona ledgeriana

Abstract

The alkaloids produced by leaf organ, root organ and root suspensions of two varieties of Cinchona ledgeriana have been determined quantitatively by HPLC. In contrast to previous findings, the root organs and root suspensions yielded quinine and quinidine. The root cells release alkaloids into the suspension medium.
