Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound. It is a 7-O- glucoside of luteolin.
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. [6]
