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

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