Flaveria chlorifolia is a perennial herb up to 200 cm (80 inches or 6 2/3 feet) tall. One plant can sometimes produce 150 or more flower heads in a branching array, each head with 9-14 yellow disc flowers but no ray flowers.[4][5]

Chemical composition

Quercetin-3-sulfate 3'-sulfotransferase is an enzyme that uses 3'-phosphoadenylyl sulfate and quercetin 3-sulfate to produce adenosine 3',5'-bisphosphate and quercetin 3,3'-bissulfate. The enzyme can be found in F. chlorifolia.[6]

Ombuin 3-sulfate, the sulfate conjugate of ombuin, can be isolated from F. chlorifolia.[7]
