Isoflavonoid
Isoflavonoids are a class of flavonoid polyphenolic compounds. They are biologically active compounds, such as phytoestrogens, produced by pea family plants.Isoflavonoids are derived from the flavonoid biosynthesis pathway via liquiritigenin or naringenin....

Fabaceae
The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, is a large and economically important family of flowering plants. The group is the third largest land plant family, behind only the Orchidaceae and Asteraceae, with 730 genera and over 19,400 species...
