Reading the bitterness
Taraxinic acid β-D-glucopyranosyl ester is a type of sesquiterpene lactone found in the leaves of common dandelion (Taraxacum officinale), a glucoside formed by esterification of taraxinic acid with a β-D-glucopyranosyl group. A 2023 review organized this compound and its dihydro derivative as constituents derived from T. officinale, compiled HPLC/MS and isolation studies, and positioned it as a major sesquiterpene lactone in the leaves.
This organization is based on compilation by the review of multiple preceding studies; the primary paper that first isolated and identified this compound remains unread in the present survey. Therefore, quantitative values of specific content in the leaves and the contribution specific to this compound in the overall bitterness of dandelion are not shown within the scope of this review.
