Luteolin-7-O-rutinoside

Substantial quantities of luteolin-7-O-glucuronide, luteolin-7-O-glucoside, and luteolin-7-O-rutinoside occur in Red Oak Leaf and Lollo Rosso, two red-leaved varieties of lettuce (Lactuca sativa) [Llorach et al., 2008], Polymethoxylated flavones such as nobiletin, scutellarein, sinensetin, and tangeretin (Fig. 1.8) are found exclusively in citrus species [Crozier et al., 2006c], while diosmetin-7-O-glucuronide has been isolated from the fruits of a Chinese herb, Luffa cylindrical.

The artichoke head, an immature flower constitutes the edible part of this vegetable which is grown widely around the world with Italy and Spain being the leading producers. Artichoke heads contain antioxidants and the main phenolic compounds are 5-0-caffeoylquinic acid with smaller amounts of 1-O-calFeoylquinic acid, 1,4-0-dicafFeoylquinic acid, luteolin-7-O-glucoside, luteohn-7-O-rutinoside...
