Biological Activities
Compounds
Digitalis grandiflora is a plant species known to contain a variety of important polyphenolic compounds. Among these chemical constituents, flavonoids play a significant role in the plant's composition. These substances are primarily found as flavone glycuronides distributed throughout all aerial organs, with the exception of the seeds. The flowers also harbor supplementary flavonoids, which are particularly concentrated within the stamens. Specifically, research highlights the presence of a kaempferol derivative in these floral structures.
