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]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
