Phytochemicals

The raw flowers contain diverse phytochemicals, including polyphenols, such as flavonoids apigenin, isoquercitrin (a quercetin -like compound), and caffeic acid, as well as terpenoids, triterpenes, and sesquiterpenes. The roots contain a substantial amount of the prebiotic fiber inulin. Dandelion greens contain lutein.

Taraxalisin, a serine proteinase, is found in the latex of dandelion roots. Maximal activity of the proteinase in the roots is attained in April, at the beginning of plant development after the winter period. Each dandelion seed has a mass(weight) of 500 micrograms or 0.0005g (1/125 of a grain).
