Abstract
The relative importance of breakdown on the accumulation of indole alkaloids has been determined in suspension cultures of Tabernaemontana divaricata and Catharanthus roseus by the feeding of stable isotope labelled alkaloids. In all cultures a considerable amount of the alkaloid biosynthesized was broken down. The breakdown was found to be dependent on the culture period and the half-life was in the order of several days. The breakdown could not explain the difference between producing and non-producing cultures. Further it was determined that in both cultures the breakdown was due to both biotic and abiotic factors.
