Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound. It is a 7-O-glucoside of luteolin.
Natural occurrences It can be found in Ferula varia and F. foetida in Campanula persicifolia and C. rotundifolia, in the bamboo Phyllostachys nigra, and in Teucrium gnaphalodes.Flavonoid Aglycones and Glycosides from Teucrium gnaphalodes. F. A. T. Barberán, M. I. Gil, F. Tomás, F. Ferreres and A. Arques, J. Nat. Prod., 1985, 48 (5), pages 859–860,
In food It can be found in dandelion (the highest concentration in the flowers, but also in the roots) and in Cynara scolymus (artichoke).
Biosynthesis and metabolism Flavone 7-O-beta-glucosyltransferase, characterised from parsley, forms the glucoside of the flavone, luteolin.
The glucose unit is transferred from uridine diphosphate glucose, with uridine diphosphate (UDP) as byproduct.
A cynaroside 7-O-glucosidase has been identified in the artichoke.
