Eupatolitin is a chemical compound. It is an O-methylated flavonol, a type of flavonoid. Eupatolitin can be found in Brickellia veronicaefolia^[1] and in Ipomopsis aggregata.^[2]

Glycoside[edit]

Eupatolin is a eupatolitin glycoside containing a rhamnose attached at the 3 position. It can be found in Eupatorium ligustrinum.^[3]
