The presence of diversity in the Stellera chamaejasme population was found via their chemical composition. The eight collected samples were grouped into two chemotypes on the basis of the amount of neochamaejasmin B and chamaejasmine. Diversity was also found in the amount of afzelechin. The stereochemistry of neochamaejasmin B was confirmed by NOE experiment.
