the highest amount of alkaloids. In this collection, 5-MeO- 
DMT was the predominant alkaloid in all plant parts, except 
the seeds, where DMT was found in the highest amount. How- 
ever, it should be mentioned here that the seeds were not fully 
ripe at the time of collection (seeds *‘December 1972”’).
