Trifolin is a chemical compound. It is the kaempferol 3-galactoside. It can be found in Camptotheca acuminata,[1] in Euphorbia condylocarpa[2] or in Consolida oliveriana.[3]
Kaempferol 3-O-galactosyltransferase is an enzyme that catalyzes the chemical reaction:
UDP-galactose + kaempferol → UDP + kaempferol 3-O-beta-D-galactoside (trifolin).[4] It can also be found in seedlings of Vigna mungo.[5]
