Reading the bitterness
Leaves of artichoke (Cynara cardunculus) are a different plant part from the edible receptacle and bracts. The EMA (European Medicines Agency) assessment states that dried leaves contain 0.4% bitter sesquiterpene lactones, of which cynaropicrin accounts for 47-83%. It also records earlier findings that this content is highest in young leaves.
Another review states "The bitter taste of artichoke plants is attributed to its high content of sesquiterpene lactones, especially of cynaropicrin" and continues "Cynaropicrin contributes to approximately 80% of the characteristic bitter taste of artichoke, which is associated with the activation of bitter sensory receptors". It positions cynaropicrin as a major contributor to artichoke bitterness.
Both sources are reviews or assessment documents integrating existing literature; the authors did not directly measure the contribution to bitterness through new sensory tests or receptor assays. The individual primary study underlying the approximately 80% figure is not given in the review text. The edible receptacle and leaves are different parts and should not be confused.
