✦ Synopsis


IN a recent communication' we reported that the administration of sodium acetate-l-Cl4 to Bauuolfia serpentina plants led to the formation of radioactive ajmaline (III) which had one half of its total activity located at C3 and C19. This result is consistent with the biogenetic scheme illustrated in Fig. 1. The poly-&-keto ester (I) is formed from three molecules of acetylcoenayme A. A one carbon side chain derived from formaldehyde, or its biological equivalent, is introduced at C3. Feeding experiments with sodium formate-C 14 substantiate this idea2. At C4

Timecourse studies were performed which compared the influence of 5-methyltryptophan to tryptophan on alkaloid formation in ergot strain SD-58. Evidence was obtained that confirms the role of tryptophan as an inducer of alkaloid synthesis. Additional studies were conducted to determine the incorpora
