The discovery of isoflavonoid was in 1842, when Reinsch and Hlasiwetz obtained ononin from the roots of spiny restharrow (Ononis spinosa L.). Its structure was later determined by Baker et al. as Formononetin 7-O-glucoside (1933). Since then, most isoflavonoids have been found in Fabaceae (bean family).

First isoflavonoid found in non-bean family was iridin from the rhizomes of Iris florentina (Iridaceae) by de Laire and Tiemann (1893). The first structural identification was Prunetin from Prunus species in 1910 by Finnemore.
