Cynaroside (also known as luteoloside) is a flavone, a flavonoid-like chemical compound. It is a 7-O-glucoside of luteolin.δ 3.42 (1H, t, J = 9.0 Hz, H-4′), 3.49 (1H, t, J = 9.0 Hz, H-2″), 3.56 (1H, t, J = 9.0 Hz, H-3″), 3.60 (1H, m, H-5″), 3.68 (1H, dd, J = 12.2, 5.6 Hz, H-6a″), 3.85 (1H, dd, J = 12.2, 1.8 Hz, H-6b″), 5.10 (1H, d, J = 7.8 Hz, H-1″), 6.44 (1H, d, J = 1.8 Hz, H-6), 6.63 (1H, s, H-3), 6.83 (1H, d, J = 1.8 Hz, H-8), 6.95 (1H, d, J = 8.0 Hz, H-5′), 7.41 (1H, d, J = 8.0 Hz, H-6′), 7.43 (1H, bs, H-2′)δ 61.7 (C-6″), 70.3 (C-4″), 73.8 (C-2″), 76.8 (C-3″), 77.4 (C-5″), 95.8 (C-8), 100.5 (C-6), 100.7 (C-1″), 103.7 (C-3), 106.3 (C-10), 113.8 (C-2″), 116.5 (C-5′), 120.3 (C-6′), 122.6 (C-1′), 146.3(C-3′), 150.4 (C-4′), 158.0 (C-9), 161.8 (C-5), 163.9 (C-7), 165.8(C-2), 183.1 (C-4) 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 in Campanula persicifolia and C. rotundifolia, in the bamboo Phyllostachys nigra, and in Teucrium gnaphalodes. It can be found in dandelion (the highest concentration in the flowers, but also in the roots) and in Cynara scolymus (artichoke). Flavone 7-O-beta-glucosyltransferase adds a glucose to luteolin. A cynaroside 7-O-glucosidase has been identified in the artichoke.
