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]
