Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound.

It can be found in Ferula varia and F. foetida[1] in Campanula persicifolia and C. rotundifolia,[2] in the bamboo Phyllostachys nigra,[3] and in Teucrium gnaphalodes.

[4] It can be found in dandelion (the highest concentration in the flowers,[5] but also in the roots) and in Cynara scolymus (artichoke).

[6] Flavone 7-O-beta-glucosyltransferase adds a glucose to luteolin.

A cynaroside 7-O-glucosidase has been identified in the artichoke.
